and the hits just keep coming for the 2.4 ecotec
I've been driving a 2012 Terrain for 9 years now and I'm just learning about this. Thanks for the info!
just finished this job on a 12 its doing great!
I have a 2012 Verano with 70k miles. It’s my daily so far there is zero issues the last 3 years. Hopefully it will hold up.
I have 2013 Equinox 2.4L. 230km on it. Runs beautiful, but uses oil. Was -21C on Monday Jan 21, 2019 when my wife drove 20km at 80km/hr then slowing down to a light the engine stalled. No warning. No lights. Pulled off to side of road and would not start for her. Checked the oil and it was low. Went to top it up and was surprised to see it took 3 liters and was not on the dip stick yet. Looked under and could not see any leaks. Left if for the night and went surfing on the net when I found your post. Next day found it was leaking oil from the rear main seal when running. Took off the air breather and found a ton of water in the pcv. Was frozen and blocked for sure. Called the dealer regarding the service bulletin. They told me my VIN was not included in the service bulletin. So I took off the intake and found the pcv hole completely plugged and I cleaned it out. Called GM Canada and they said same. Can not help me. Had I been notified when the bulletin came out It would have saved my engine. I replaced the rear main seal and now the engine is making a deep knocking noise. Next to take the oil pan off and have a look at the crank shaft for spun bearings. Bad GM. Shame on them. Such a simple fix not shared with all. My car had been in at a GM for recall for a rear wiper motor joint and rust along the bottom doors, but nothing about this. Ahhhhhh
See what came out of my air intake....

Unbelievable. Samething just happened to me yesterday 😒☹ My vehicle is sitting at a dealership right now because of the EXACT samething!! My stomach is sick! I just got my car back, they already had it for a month due to a accident I had and now this😔
I got one here at my shop, dropped the whole trans and the engine together. Sure enough rear main seal is folded over and PCV had a lot of water inside. Thanks for the post!
Thanks for sharing your the story! Sucks these fail so often like this.
Just traded off my 2015 equinox 77000 miles burning oil done with gm happy subaru owner now
When I went to begin the oil consumption test per the Executive Resolution Liaison the dealer notified me that I have water in my PCV system and I need to get it cleaned for $700 before Tuesday when it’s going below freezing. I found the Bulletin No.: 14882 which explains that GM is extending the warranty for my 2014 Equinox to 10 years or 120k miles (mine is 73k). I called the Executive Resolution Liaison back and she pretty much said SOL your VIN isn’t listed. I told her that it’s having the exact same problem that is talked about in the bulletin 14882. She just repeated Sorry your VIN isn’t listed so it’s not covered. She wouldn’t accept the logic and just said sorry. And people wonder why we all go to Toyota and Honda. Bullying us with Patriotic duty won’t work when the company won’t even take care of you. This is enabling bad behavior on the part of corporations. We need to show them that we’re not going to take this by not buying their products. And my tax dollars helped to bail them out!
Former Gm guy for 50 yrs. I’m gone to Toyota and never come back. Gm is a dumpster fire and they make vehicles to last 75 thou mi
Same
My 2013 was not covered per the vin number. GM said they corrected the issue late in my model year. Wonder how they explain the rear main being blown out on my son's 2014? His blew out with 30 days left on the warranty. It also caused the timing chain and valve repairs to be needed. Still burned oil, quart every 1500 miles.
Perfect job, explaned everything and your ser bolition # for the GM repair was spot on. THANK YOU SO MUCH
Gm you did it again
Wow, engine is very similar to my 2.2 ecotec, luckily the pcv is going downward towards the intake tube in my car.
I have done 2 of these already because of the frozen pcv issue. Getting faster and faster at this job thanks to this common problem.
Where you located
Thanks for the video. This helped me diagnose this nightmare of an issue. The extreme cold around Christmas this year caused the seal to blowout on my '17 Terrain, 67k miles. $3200 fix at the dealership. I should have done my research better. I feel for others that are having this same problem. I doubt I'll ever by another GM vehicle. Thanks again!
@avshockey, did you have a warranty, the same issue is happening with mines and the same car
@@BlkPhoenix38 No warranty. GM did cover some of the cost. It was around $800 out the door for me. Check with a few different dealerships and mention GM Service bulletin 14882. The first dealership that I took it to (same place that I bought it from) tried to charge me $3000+ just to replace the rear main seal and they claimed to not know about the service bulletin (which was bullshit, they were a Chevy dealership.) Called around and found another Chevy dealership that contacted GM and then quoted me $800. I took it there. Thankfully it's been good since. I'm sorry that this is happening to you. I wish you the best of luck.
@@AvsHockey77 thanks man, this is very helpful
My 2012 Terrain blew the seal 2 weeks ago (113K miles). GM was like a broken record, your VIN is NOT covered under the bulletin. The car was at the dealer where purchased and said same thing. They wanted $2300 to fix it. Timing chain was fixed at 90K. It's bad again now. After speaking with the owner...service manager said they would give 20% off to fix it! Had it towed to a friend for 1/3 price. It will be gone in a week (hopefully). Can't wait for the class action suit.
Sorry to hear about your bad experience. It's cases like yours that are going to cause GM to eventually go bankrupt
I have watched the evolution of the crankcase ventilation systems starting with the road draft tube. Even that was more reliable than this system. I have a 17 Terrain in the shop right now, guy just had the rear engine seal replaced at another shop, but they failed to fix the problem-pressure in the crankcase. I am tempted to supply an old fashioned PCV valve, tee into the big vacuum line at the intake, route it directly to the valve cover (where all the fumes are) and create a functional crankcase vent. Just like the old days,70"s
Great video! I came looking for a good real world example of this fault to use as a teaching aid and this is perfect! Thanks!
Thanks man, glad you found it useful!
@@NoNonsenseKnowHow just happened to my sons 2012 Captiva after a few days of sub zero temps. Dealer wants $1800 to fix it. 150k miles.

2010 GMC Terrian . RIP 3/4/19 130,000
Excellent video Again!
Thank You NNKH!
The 2.4L is a very good engine (good power, good mileage, and decent to work on as well), but has this pisser of a design issue.
This engine also has a tiny oil filter and needs to be changed more often than the "idiot-light" indicates.
Through a few forums, and this video, I have found a good and efficient fix for the water build-up problem... Adding a $40 oil & water separator system to the PVC line before the intake.
This creates a low point for water to accumulate and is easily drained.
I empty mine every 2500 miles when I change my filter and get an amazing amount of water & sludge every time.
This eliminates the water accumulating and freezing in colder climates and also purges out excess vapors in the system.
Add the pressure vent oil cap as described and these should prevent seal blow-out...which is a major pain.
No issues after 15K.
Cheers
Dean
I know I am kinda off topic but do anyone know of a good place to stream newly released tv shows online?
@Arian Finnegan Flixportal :D
@Aldo Melvin thank you, I signed up and it seems like a nice service :) Appreciate it!!
@Arian Finnegan No problem =)
Good idea! Can you post some pictures. I have a 2012 Terrain 2.4 with a blown rear main seal. I am working in addressing this issue. Thanks!
I'm going to go look at a couple of the car forums for more information. I believe that the pipe running from the air box to the valve cover is the "Fresh Air Intake" portion of the PCV system. If this pipe has excessive blow-by in it, the PCV passageways are plugged inside the engine. An Oil Catch can on this pipe would be a Band-aid on a failed system. The intake manifold needs to come off, and the PCV passageways need to be cleaned out.
You are correct, it is the "clean side" PCV or as you say "the fresh air intake" PCV.
Yes a catch can could help, but it must be mounted lower them where that PCV goes into the crankcase.
An alternate "band aid" is a vented cap with nylon ball from CFM performance in FLorida.
Thumbs up 👍 seeing you doing this is awesome 😊
Great video same thing happened to my equinox
I just took to shop. I will never buy another one
I forgot to also note that driving short trips or a stuck open thermostat usually cause the excessive moisture buildup in these PCV systems. If you drive longer distances regularly you are much less likely to see this type of failure(Since the engine warms up fully and has sufficient time to "burn off" the moisture) Also, I said in this video that this was a recall when indeed I believe it is only a service bulletin.
I have and others on the Equinox forums have found just the opposite. Extended highway driving in cold weather, high moisture, low to moderate loads is when the moisture, and emulsified oil builds up. The fixed orifice in the intake does not draw enough air flow due to low vacuum and small orifice. Under load, cruising on the highway in overdrive, there is positive pressure in the crankcase and not enough vacuum on the fresh air side of the throttle body to remove excessive moisture. I have taken extensive vacuum and pressure measurements in the crankcase and intake. You are absolutely correct about the downward sloping tube to the reservoir. This is a bad design. I have been telling people for years now to replace the tube with a flexible hose so it drains back to the intake and to use air/oil seperator on the fresh air side. People dont even check their oil most of the time, so checking and draining the separator will overfill too. At the least GM should have put out a TSB and notified customers to regularly check the tube and reservoir at each gas up, but that would create liability for them. I haves used a separator and it works great but there is maintenance. I also installed a drain on the stock reservoir as an alternative to the separator.
i caught that i said recall huh
Ugh. Exactly the scenario on my sons 2012 Captiva. He drives it back and forth to school and to the gym. All short trips. Only had the car a few months before the seal blew.
@@tssci6774 are there any specific air to oil separators you don't mind listing? Not sure which one would work on my 2014 Chevy Captiva
@@johnramon5010 I dont know the layout of your PCV system or intake on the Captiva. The catch can/seperator are mostly the same. Get one that has multiple chambers and baffles. Identify the hose routing for the PCV system. Then locate a mounting location for it. Lots of videos for the Equinox/Terrains. At a minimum, get an AC Delco FC-219 vented oil cap to protect from overpressure if the system freezes.
I own a 2016 Equinox with a 2.4L with just over 100,000 miles. I bought it new in 2016. Last deep freeze in December 2021 my PCV system plugged up and blew out the rear main seal dumping 5 quarts of oil instantly on the highway at 70 miles per hour. Of course the motor was destroyed in a matter of seconds. It bent valves, wrecked the timing chain, etc. I called my Chevy dealer and they said "Sorry your out of luck." , but yes there is a technical service bulletin out on this but you are out of warranty. My only choice was to dish out about $4000 on a junk yard motor and installation. This is a very common problem. I wish they would of at least had the decency to send me a letter letting me know about this issue so I could have easily prevented it. Since this happened to me a few weeks ago I found this car is on the list for many other issues including paper thin frame underneath which rots out in about 8 years, timing chain issues and a few more. I am afraid to drive it now so I traded it in on a Dodge Caravan. No more GM / Chevy for me.
Thank u, very helpful
Scary leak. You'd need a oil tanker following you
Oh my Lord. Transverse mounted engine too.
Back in the late 1970's my engine builder handed over my fresh 402 BBC with a leak like that. Took me and a buddy 3 hours to R&R the eng/trans to replace crummy seal with a top of the line McCord seal.
Great example of why transverse engines installed from underneath and in a cradle from the factory Suk Balz.
Yeah the old school chassis had plenty of room. Now you need a 2 post lift. $$$$
I see ridiculous prices of any rear wheel longitudinal drive cars. "To the moon Alice!
This happened to my 2012 terrain, luckily it was barely under 100k so it was covered. I had found the bulletin but the dealer said it wasn't covered under it even tho I had it listed my engine code on the bulletin. There is a temporary fix in the bulletin to drill out part of the pcv system I had the dealer do it. Basically this all stems from these engines poor design and excessive oil consumption.
Was the part needing to be drilled that small hole in the intake manifold?
there is a class action but only for certain states. find the attny's doing the case and they will send you a doc file to fill out. this is to try to extend the action to cover everyone.
what state are ding this
Great video, and I am another victim, just got it back from the shop yesterday. The intake manifold clear out books at 3.4 hrs, the rear main at 9.5 hrs. I am "lucky" to have a shop with a discounted shop rate, but even then (Canada) after taxes and fluids (including a trans flush which was due) $1829.00The $38 seal change requires a complete disassembly of the entire car below the body work. Subframe, steering, transfer case, suspension.....
Hahaha I'm fuuuuuuccckkkeeddd
Where are you located, I have a 2010 2.4lt4cy equinox. I bought it in august privatly. I have been driving it all winter so far with no problems. I park in the underground, which I guess helps.
So irritating that I just finally came across this video right after I fix my vehicle. For me I didn’t blow a rear main seal luckily, but I was getting reduced engine power and stability track message making my 2011 GMC Terrain 2.4 run really rough. Not sure what to do, I changed out the throttlebody, but I kept noticing the same brownish watery oily crap coming out of that tube as well contaminating my air intake system. That little hose is a special order part and took a few days to get in. I cleaned out that little tube as best I could and put the new hose on (BTW that little hose is a bitch to get on, I had to cut the old one and I’m pretty sure I slightly broke the new one a little bit trying to slide it on).
Got the vehicle working again but I’m not sure how long it’ll last. This vehicle is riddled with problems. It eats oil like crazy and of course I’m past the recalls and warrantees on many of the issues because I have so many miles on it. I was thinking about bypassing this hose but wasn’t sure how that would affect fuel mileage or anything. It seems like it would make sense to bypass it, and I think that’s why there so much carbon buildup on the throttle body, because these crappy fumes are being recycled in the air. Wouldn’t it be better for just fresh air to be running through the system?
Anon yes bypassing this and just putting a pod filter on it is a sure way to eliminate future problems. but I would also look into cleaning the passages under the valve cover and the PCV ports in the intake manifold as well
Will do. I appreciate the swift response and suggestion. It’s much appreciated and great video by the way.
NoNonsenseKnowHow Also to note, I think I caused my own problem because my vehicle burns oil, I have to continuously add oil to the system. I must have missed read my dipstick and added way too much oil. This would explain why junk was getting sucked up into that PCV tube. Once I drained the oil and replaced the tube, my problem went away. You may note that in your future issues with this problem, ask if they’ve just had an oil change or have added oil to their system…
@@FromDream2RealityNow did gm redesign this tube that was back order?
Only some have the Special Coverage for this issue. for the couple years i have worked in a Chevrolet Service Center, i think i have only had about three of these vehicles come in with a Special Coverage for this. If you don't have a special coverage you are almost guaranteed to pay at least $1500 or more. This is because you have to remove the transmission and clean up the intake/pcv to avoid it happening as soon as you accelerate out of the shop. Extended warranty's hear 2010-2015 Equinox and rear main leaking and send a inspector out instantly. No coverage if caused by the PCV system freezing. We see about two or three of these come in each week in the winter. It's a misconception to think that you will get this issue resolved for free unless you are a person with a lucky VIN.
Getting this fixed now and yep my warranty didn't cover, is there anyway for the company to produce a better engine cause I got a 2015 and I see the recall was for past years the mechanic told me once they do the modifications it won't happen again
If you let them idle to much to warm up in cold areas, the engine dont get hot enuff , that creates moisture. I did a autopsy on my wifes car. They dont build alot of heat idleing.
This happened to me a month ago. Pcv froze, blew out my rear main and by the time i even got an oil light on my dash the damage was already done. Spent 4k on repairs including rear main, intake manifold gasket and exhaust cam solenoids. Pretty sure the dealer screwed me on this one as now i have an immense amount of positive pressure blowing out my oil cap had enough to blow my hat off my head. Brought it back to the dealer and they said this is considered normal blow by. Wouldn't even compression test it to see if i have a compression leak. I'm no mechanic but everything I've read about this indicates i have bad piston rings. So i paid all this money to fix an engine that's probably about to die anyway.
I live in Denver, CO and this happened to my 2012 Chevy Equinox. The exact same engine that is in the video. Much like Ron Deshane, I was told that my care did not have the proper VIN # to warrant a repair. The difference with mine is that I had no clue that anything was wrong until I was going 50 mph down the interstate when all of the oil blew out of the back of the engine, destroying it in the process. $8700 to repair/replace engine or buy another vehicle? I went with another vehicle.
GM sold out.
That's why I bought a Subaru Outback when decided to drive out to Colorado from Ohio
Same here. Still looking for the class action law suit to join. If anyone has the link, please share!
I just read an article that named the gm 2.4 engine as being in a top 5 list of worst engines ever made..i believe it!!
Yeah I would have to agree there are some definite design flaws
And u can add in the Gm 3.6 which is even worse.
@@mikecastellon4545 and 3.0
Top 5 worst. No. It’s not that great if an engine, but many other engines 100 times worse
The GM bulletin 14882 is VIN specific. If your VIN is not listed it will not be covered, unless you have a powertrain warranty or if your vehicle is still covered by the manufacturer warranty. I spoke to GM personally to confirm.
Why is it vin specific? Did they redesign the system so this wouldnt happen?
@@ryanchristensen1799 They told me only certain suppliers produced bad parts and those cars are the ones they are covering. Funny though how many are affected that are not part of the so called affected vin cars. GM is just trying to look like they are addressing the problem and actually doing nothing. Wonder if any vins are actually included? Their advice to me, was to drive a different car in cold weather. Didn't know I bought a 3 season car.
@@edknn3515 Same story from GM - when I asked for measurements on the 'changed' PCV port they said they aren't mechanics and can't tell me that. Nothing was changed - same clogged issues from improperly designed too small PCV port in the manifold. CFM makes a breather to help if over pressurized and oil catch can will help, but still need to keep cleaning the small manifold port routine as the design itself is prone to keep clogging.
I am having build up (oil and water) in that little box within the outlet duct. What did you mean by putting a valve where the pcv tube is? Do you have a specific example of what to use or any other possible solutions? I would appreciate any help. This car runs great and I have taken great care of it and this issue worries me. Thanks ahead of time.
Drill a 1/4" hole in the oil cap and stuff a little cotton in there to filter the hole. Excess crankcase pressures will be relieved and not blow the seal. Not really a fix but much cheaper than replacing a seal.
There is a 'ventilated' oil fill cap available. It has such an orifice that will open above 1psi. Just saw it's referenced further down.
My rear main seal blew out a year ago! Due to that pcv water freezing! That drilling a whole to where the water goes def help my vehicle haven’t had a problem with it since! Oh and make sure you take to your dealer at least once a year to have them clean the whole pcv that will help in the long run!
I had a 2012 Terrain with the same problem. I sent the service manager the bulletin that I found referring to the 2.4. He done some research and said mine was covered under the warranty. The warranty was extended to 10 years or 120,000 miles. I’m at 72,000 and it’s a 2012 model, so he says we’re good. He got the repair done and found exhaust and intake actuators are bad and throttle body needed cleaned. That’s gonna be 400 bucks. He gets that done and calls me and said he is sticking to his word, but General Motors says my vin wasn’t covered. Thankfully he got them to cover the rear main seal replacement. He is gonna show me what they done when I go get it. Now I’m thinking, is it gonna be a warm weather car now? The main blew when my daughter was on her way to work and the ambient temperature was 15 degrees Fahrenheit. Very frustrating to say the least. At least my service manager didn’t back up on me. I’m so thankful for that.
He just cheated Gm and charged it out on another vin..Seen it happen a million times.They are crooks at the stealership.
My wife's 2016 Terrain just had this same issue. We have to park it outside, in Alberta canada. Any updates on what we can do to prevent?
Seems be a problem on exonox no issse on 06 colbolt ss
We have a 2012 Equinox 2.4 with the same problem.Sent my customer with a copy of the 14882 special coverage bulletin from 2015 and warned him how GM is better at selling the cars than standing behind them.Guess what they will not cover it.The local GM dealer had two vehicles with the same problem there.That said with this bitter cold winter nation wide this must be a catastrophic problem.We also had one show up this week 2013 Captiva with the same 2.4 frozen pcv problem rear main blown out.
Patrick Chamberlain yeah I was thinking the same thing as you! With these crazy temperatures we've had this year so far. Thanks for sharing some information! And hopefully film the video helpful.
I got the same response. They will not stand behind their product despite identifying that their poor design in the right conditions will cause the failure. Overall I’m highly disappointed in the GM customer service and failure to stand behind their product. Out of necessity I am taking the small assistance they have given to me on this and moving on. GM will be hard pressed to get any new business out of me after this poor customer experience.
I have a 2012 GMC Terrain in the shop today and lucky for him he did not have this problem.Thinking about this a cut about a inch and a half off his PVC tube to change the angle to slope down.I think this is what GM should do for people that own these vehicles.
My 2013 Captiva has the same problem. Started at 100,000. GM said my car was a no go for the fix due to the VIN. It had to start with a different number
would a vented oil cap reduce pressures?
Would you be willing to show CZcams a basic example of how to bypass and or reroute this hose properly? With so many people having this issue, I think that would be a great video, and it would be good to post on Chevy and GMC forums as I see many people on there with the same issues, it would help draw more viewership to your CZcams channel.
Sorry for some reason I just saw this comment now. I'm guessing somebody else has already made a video on how to bypass it?
@@NoNonsenseKnowHow nobody has yet to make a very good one, there's a video that shows a pretty decent idea of how to bypass it, although not sure if I trust it
@@NoNonsenseKnowHow czcams.com/video/dPIJDe3JT-s/video.html
Just some info I learned. Gm makes a oem vented oil cap, is like $9 on Amazon. If your engine internal pressure builds up the cap releases the pressure saving your rear main seal. If does release pressure you may see oil around your oil cap. I have a 14 Terrain, supposed to not have the oil use issue but I am still taking proactive precautions. Bought it with rebuilt title already repaired for $7k with 52k miles on it, I need a cheap awd vehicle for winter. All I have read is watch oil on these, change oil around every 4k miles. Clean out or check pcv line.
Awesome, thanks for the updated info. Do you have a link for that part on Amazon?

This just happened to my 2014 gmc terrain and is covered under the manufacturer warranty. It's not a recall I just got lucky with the 5yr 100k mile warranty
What was your mileage when it occurred?
@@ryanchristensen1799 98k
Just happened to us today. 64k miles on 2014 2.4
@@steveecker2364 if you call a GMC dealer you might still be under manufacturer warranty. I hope it works out for you.
Regarding that pressure build up and effect of that (blowing out the rear main seal) what do you think of a vented oil cap? I'd appreciate any insight or advice.
Replace the stock oil filler cap with a AC DELCO vented oil filler cap FC-219. This will bleed of the excess pressure and save your engine. I did this to all my family's equinox, 6 of them. We love our equinoxs.
This just happened to me on a brand new GM installed engine with 100 miles on it.
They may have not found that the intake manifold might have a carbon build up.
Can this be fixed without pulling the engine? I pulled the intake manifold, cleaned the ports, still have positive pressure at the oil cap. The rear main is blown on my equinox. I can’t afford to fix it. I can’t afford a payment. Everything I see says you need a lift. Is there another way?
the angle dosent matter it has such a high suction the water goes in no matter what the only cure for canada is a catch can on the vent line and drain every two days or it will over flow back to the intake box
Grant Mallery
correct... angle does not matter.
Another solution is a vented oil filler cap with nylon ball for $80 from cfm performance in Florida
I own a 2011 equinox with 114k miles an you can take that air hose off everyday an it pours out water an gunk winter or summer in Michigan
I know this isn't supposed to be done, but I'm considering plugging the air box hole and venting into the atmosphere during the coldest days. It won't take any longer to do this than to empty water out of the air box.
+deere3321 yeah that's personally what I would probably do as well. I mentioned that in the video. Maybe just put a crankcase breather filter on top of the valve cover. But it would be a good idea to also pull your valve cover and clean out the ports inside of their as well as they tend to get clogged up
Thanks. GM said they would do the TSB at my cost. My VIN isn't covered.
Do you think a filter is necessary for temporary use?

Any words of wisdom will be much appreciated
Would it be better to to an engine flush treatment when you do oil changes?
I honestly don't think that would help the problem. I don't recommend engine flush is because if you do have sludge build-up you don't want to loosen that stuff up and send it through your oil system

I appreciate the video. It helped me tremendously because I had no idea why my rear main blew out and I ran across your video
P.s it's 14° outside so I'm pretty positive this pcv crap is my problem
Hey ive got a 16 equinox 2.4 auto awd. Its showing 3 codes i think, p219a, p0420, p0014, p0013 which is mostly timing stuff, fuel air mix, exhaust. it runs great one trip next time splutters everywere with lose of power until get plugs burning hot or something. Ive definatly gotta get a new hose that goes to use to be a pcv on Valve cover. But can you tell me what i need to do the timing completeley. lifetime warranty parts i dont like when their cheap because it means ill still have to do it again. If you have time id like to know what to buy and a fair brand something to actually last. Also my engine had the tube stopped offf on engine so lots seals and gaskets leak. What seals and gaskets that wont come in a kit can i replace while tearing into that part of the engine and any other things you would suggest changing instead of what i said? Any seals i can get to def needs done. it has abt 200000. people complains abt the 2.4 but ive not had to do anything until now with a lil over 200. ours has been great and we live in the WV mountians so its been used well. I hope you can find the time, Thanks !!!
This just happened to my wife's 2017 Equinox. Destroyed the motor. Worst part is the extended warranty won't cover the replacement.
just happened to my 2017 equinox, what is the best thing to do ?
i have same problem 2012 equinox can you tell me how much pressure it takes to blow the oil seal i am going to put a small pressure release valve in the oil filler cap but it will not release pressure until it reaches 25 psi is that too high or not low enough what do you think thanks
Im not sure. I will say I think 25psi is wayyyyy too much
I see a BUNCH of stuff on the internet lamenting the small size of the orifice in the intake manifold.... that is just a insignificant problem compared to this vent icing shut. JMO
Intake manifold ports are clogged.
Is the 2017 chevy equinox lt awd 2.4l affected by this too? Or did they do something different to fix this issue? Please reply!
Looking for this answer aswell
Im having this issue on our 2010 equinox 4 cyl, need to monitor the pcv line daily and take in to thaw over night and reinstall pcv line and air intake, pain in the butt but it keeps from freezing up and pushing oil out of rear seal which seems to happen too much on these vehicles, We love the vehicle other then this issue.
That's great to hear you're taking preventative steps to prevent a failure! Thanks for sharing and let me know if you happen to come up with a more permanent fix.
NoNonsenseKnowHow . I was lucky, my oil did come out of rear seal but if I keep this up by taking the air box in my oil level stays full and the seal stays sealed
My father have 2016 chevrolet equinox here in ontario canada he drives his car to work during cold afternoon the car starts leaking oil undercoating the entire car ,got it towed to dealership told us its a rear seal leaks told us its not under warranty and not on the bulletin ,$1600 just labour itself to fix it we are not rich barely have money for it , car its not built and engineered for cold weather conditions its very sad he just had it a year it’s frustrating depressing
Rear main seal just blew out of my '13 equinox . Went to Chevrolet dealer and was told that GM SERvice Bulletin #14882. was "vin specific". Even though I own a 2013 Equinox that my specific vin number was not included in the coverage as stated on the bulletin. I said the bulletin says 2013 Equinox and that is the vehicle I own and the one which just blew out the rear main seal. This is the third person at GM I talked with and pretty much was told tuff shit. So if you have this problem don't waste your time talking with GM because they are going to weasel their way out and not be able to give you a definate answer as to why they wont fix your car even though according to the bulletin they should. I have owned nothing but chevys my whole life, including the five I now own: impala, blazer. equinox, and 2 corvettes. I will probably being looking elsewhere this spring when we get ready to trade off the impala for a new car. I have my doubts the GM will honor any problems that may occur out of warranty on a recall or service bulletin!!
Damn, sorry to hear. Ridiculous that they won't fix every last one of these that blow a rear main seal. It's obviously a design flaw
Just happened to my car!! Bulletin 14882 extends a certain warrenty..but only to certain vin numbers???
Amy Snyder oh damn! im sorry to hear! :( honestly, I'm not sure if it by VIN number. I would call the dealer or look it up on google.
We got the same reply from the dealer. " Yours is not one of the affected VIN numbers" But it still broke.
Class action lawsuit anyone? I want a new, redesigned engine.
I just checked with GM yesterday. Mine is a 2011 Equinox and is not included. When I asked why, I couldn't get a response. I have owned GM products for 50 years. Not any more. GM knows there is a huge problem and won't back it up.
Total bullshit.... lets all band together for a class action lawsuit!! Im getting mine out of the shop today and dumping it. Looking for a new ride... never again buying a Chevy
I'm with you... 2013 and both front and rear seals ..warranty expired 2-22 and i just found out last week
It's been a month since I ordered the gasket kit to fix the PCV problem. Amazon just asked me if I still want it because they still don't have any idea when it will be available. Is this indicative of the scope of this problem? Am I better off just replacing the the entire manifold since it's only $101?
I would just put a vented cap on it for now maybe
That might be the way to go.
These engines sound like they're coming apart when you turn them over. Most people I know who had these traded them in.
Without VVT the 2.2 L61 were pretty good.
@@ayebee1207 Not even those were good. Have one in my 05 vue. Despite using synthetic oil and the valvetrain being spotless, it burns a ton of oil, sounds like shit, timing chain tensioner went bad and is going bad again, loud, slow, don't even get good gas mileage considering
Does anyone know if I find a low mileage equinox and fix the pcv, is it a good engine otherwise? I had an older equinox and liked it. I'd like to get a newer one but I'm not sure about the engine.
They are not a great engine.
@@NoNonsenseKnowHow The V6 isn’t much better either.
I have a small leak in my 2013 Chevy Captiva. Could it be the same or something different?
Do you have the same engine? If it's leaking this bad then it's probably the rear main seal.
No, it's a very small leak. But could be the beginning....How much is an estimate repair on something like this
I had my rear main seal replaced in January of 2018... Now January 2019 I am leaking oil again. I do maintain my 2013 Equniox on a regular but I was just wondering if this is normal. Its not leaking like the seal is blown but its leaked enough that there is less than 1Qt. of oil in my car and its a little chunky on my dip stick. Note that I have not driven my car in 2 weeks when I noticed the leak. The last oil change was done in November and as I don't drive but normal day to day I change my oil at 3,000. Honestly any feedback would be greatly appreciated as money is tight right now and I don't have another $1700 to have this issue fixed.
I would bring it back to whoever originally did the repair
I have a 2013 with 2.4 ecotec engine also.
I have studied a blown rear main seal from when my mechanic did a rear main seal replace and in my opinion the design has to sharp of a corner, then when PCV's are plugged, piston blowby increases crank case pressure and causes rear main seal to fail.
A vented oil cap with nylon ball from cfm performance would prevent rear main seal failure in my opinion.
A separate problem, which you might have, since it is not your main seal that is leaking oil
Is you are burning oil. The oil from your crankcase is going up into your cylinders, getting past the oil control rings on your pistons, and then burning off as the cylinder fires. There is a class action law suit for this issue. I think in 2014 gM needed up cylinder walls and piston to counter this problem.
I can explain more about toot cause of this issue, if you want. In my opinion....
The 6 cylinder, which has similar piston and cylinder walll design does not have this oil burn issue.
The same 4 cylinder ecotec engine in lighter smaller cars does not have this issue our equinox is 4000 lbs and heavy compared to other GM cars.
When engine bogs down, lots of stress is put on cylinders resulting in blow by and resulting in oil getting into cylinders
Do not use ECO mode , it facilitates engine bogging down.
That's an insane price for a back seal
Some 4cyl engines will leak Very slowly from RMS but wow!
Do they have a vented oil filler cap for 2015 Chevy Captiva LS 2.4L flex? I'm having trouble finding one. ACDelco fc219 doesn't fit so does anybody know why, too small or too big?
I've heard they do. But I'm not sure who makes one or what the part number is
Just got rid of this piece of shit of an engine!! My advice is to get rid of these cars with this garbage ecotec engine in them!!!!
This may be a stupid question, but could a guy get a vented oil cap to possibly prevent this from occurring again? I know a little about vehicles and am a long way from being a mechanic 😊
+Randy Chandler yes. That would certainly help prevent a failure. Although it's not good for the environment and the EPA would definitely not approve. I have a pod filter style oil cap on my 1986 Mustang because I bypass the PCV system. I and not sure if they make one that would fit your style oil cap though. Probably not. But you could always put a pod filter on the Breather nipple on the valve cover.
NoNonsenseKnowHow. I will do some checking to see what’s available. Thank you so much for your help!!!
Randy Chandler no problem! Thanks very much for sharing your experience, and keep me updated if you find any good options
NoNonsenseKnowHow. Autozone shows to have a non vented and vented one. It’s gotta be worth trying. I wish I’d known this 3 months ago. I haven’t receive any recalls, other than something to do with a fuel line being exposed to road debris and can get hit and spring a leak.
Randy Chandler yeah actually I made a mistake in this video when I said it was a recall. It's only a service bulletin. and that's great, if they actually have a vented cap I would definitely go that route if I owned one of these.
Couldn't you also just loosen or remove your oil cap in cold weather before this happens?
i suppose
I am not a Chevy person and knew nothing about this damn thing. When my son bought his used at 77k The transmission broke 3 days later and the dealer was obliged to put a new one since my son was hurriedly put into this car without it being inspected. Now after adding just 10k miles to the car and two oil changes, the engine seized. 87,000 miles, oil blown out or burned somehow and the engine seized. We’re not rich by any means so what is the best option? Pull-a-part? A tested used engine? Or go to my Chevy dealer and ask them about it?
Sorry to hear, sounds like a really bad experience for sure. If it were me, yeah I would probably get a used engine from a reputable junkyard. I've done that many times in the past with great luck
If the dealer did the oil changes, I'd definitely take it back and make them fix it. That's ridiculous. Not even 100k on the clock and the engine seized up. That's just plain nuts.
I have a 2012 Gmc Terrain that I had to tow in to the dealership service department day before yesterday and was informed today that my car had this same exact issue. Frozen PCV caused moisture in the oil and pressure to build up in the engine and blow out the rear main seal. I was told it would NOT be covered under my extended warranty because it was done by "natural causes" (what?!!!) and I would have to shell out $3200 for repairs. Are there absolutely no other solutions to temporarily fix the issue if its a just a leak? Or will it HAVE to be replaced once its "blown-out"?
Yhashele Acevedo I'm sorry to hear about your scenario. Unfortunately, this is a must fix item. As you saw in my video the oil is literally pouring out. You won't make it very far and there are no temporary fixes. However if you call around to a few shops you may find somebody to replace just the rear main seal for around $800 to 1000. That would be on the cheap end though. But whoever does the repair, make sure that they remove the intake and properly clean out the PCV system. I hope this helps and I greatly appreciate a thumbs up on the video.
Thanks for helping me out it took FOREVER for me to find any information regarding this problem. So I have a just have one more question! Regarding my extended warranty which covers ALL INTERNAL PARTS within the engine, transmission, transfer case, etc. why would I be told by the dealership that the rear main seal repair would NOT be covered? Isn't that part of the engine?
Yhashele Acevedo it certainly is part of the engine, but I guess since it was caused by the cold they are trying to get out of covering it. Honestly I don't know very much about warranties or how they work. I've never had one or used one in my life. But I would be very curious how you end up making out and would appreciate it if you keep me updated! Thanks again
Figured I would ask just to have another opinion on that. So thanks again for your help! I will definitely fill you in on what happens next!
I just had the same thing happen to me. After calling GM directly, I have a preliminary response that they will cover some of the repair but not all. I plan to continue to call and request that they cover the repair totally. Not sure how it is going to go but I hope to end up with GM paying for the entire repair. Their is a special bulletin # 14882 that details this problem and what GMs response is. I was told when I mentioned this that my vehicle does not have a VIN that is covered under this bulletin. I plan to continue to fight for GM to do what is right here. Good Luck to you with your case.
it's refreshing to see what happens when the suppliers start dicking around the bean counters who laid off in-house engineers
I added an oil catch can, spliced into that PCV hose. Both ends have an arch where they drain when the engine is not running. Every 2 week in an Ontario, Canada winter , I am emptying about 300ml of watery coffee looking sludge. Summer, it may fill up 100ml-200ml in about a month or so. Very moist engines, not sure why? I am a commuter, 500km a week of highway driving. drive.google.com/open?id=1oTYy2DJmAjM1HDxn_bMSCmfLcM5h9Z5_
Awesome to hear that you took some preventive action on this issue! Thanks for sharing your experience and fix.
Can you post a picture of your catch can setup. I just started reading about this today. Replaced throttle body last night but could reach O2 sensor. Same thing happened once I popped off the PCV tubing. Ordered new hose and did some research and it seams the catch can is the ticket to save your engine.
Here is a Google folder for my setup drive.google.com/open?id=1oTYy2DJmAjM1HDxn_bMSCmfLcM5h9Z5_
@@EditNorthern where was the catch can mounted? It was hard to see from the photos. Thanks!
I put a picture of where it's mounted and what the fluid looks like after approx 800km of highway driving, -6 to -16 deg Celsius outside temps. It was about half full. I just empty it into a waste oil jug and take to the recycle depot.
Lookin at a Headache ? This is a friggin living nightmare! Pulling transmission to change a small seal, and pull the intake manifold to clean, and there is no real fix to absolutely prevent this from happening again? Damb!
There is a "fix" so to say, or a work around, and it is to buy an $80 vented cap with nylon ball from cFM performance, see my comment on the u tube thread.
Oil catch can
We have a 2015 Equinox that had the same problem! The rear main seal blew out and the oil light never came on, thus causing the engine to seize. Over $6000 to replace with a rebuilt engine! Since the 2015s aren't covered by the bulletin, we have no recourse.
That sucks, sorry to hear
@@NoNonsenseKnowHow Thanks,
What's your plan with the car at this point?
@@NoNonsenseKnowHow We had a Jasper rebuilt engine installed and just got it back today.Jasper Engines sent a bulletin that recommended cleaning PCV ports in the intake manifold, installing an updated valve cover and changing the oil filler cap to a vented 1.
@@ernestcousineau8997 got you. Okay, thanks for the update and good luck with it!
Install a vented oil cap.
Yes
Do you have a part number?
Just had this happen, I was told I need a new valve cover and they're on NATIONAL BACKORDER WITH NONE TO BE HAD ANYWHERE!!! WTF! GM !!! :-(
That sucks! Is it an updated cover?
Yeah let us know please!? Thanks!
@@ryanchristensen1799 2 days ago I got the car back! finally they scored one from the GM warehouse in Pontiac Michigan!
This happened to me and it was fixed but now I have the check engine light on with a P0016 code. Anyone else had this problem???
Is it possible to put an catch can on one of these? 🤔
Yes for sure, it would be a great idea to! I actually put a link to the catch cans on Amazon in my description since I've heard a few guys I've done it. I haven't done one personally myself though. Certainly a good idea to be proactive if you own one of these
Yes and No
Catch cans are typically put on the" dirty side" PCV orifice , but on this 2.4 ecotec that orifice is internal to the engine.
I have an elite x2 catch can with drain on my V6 equinox on the "dirty side", but that is to prevent carbon deposits on my intake valve.
This video shows the clean side PCV hose full of water gunk that is frozen.
On the equinoxforums.... someone posted putting a clear catch can on this clean side. If you do put one on, the catch can should be mounted lower then lowest point of the clean side hose where it leaves the crankcase.
An easier fix is the nylon ball vented cap, that I describe in another comment.
@@NoNonsenseKnowHow I have a 2013 gmc terrain 2.4 ecotec i want to put the catch can for the pvc tube, do i take the end off from the intake manifold to put in catch can or the other end that has the actual pvc part and if i take the end off the intake n put in catch can do i plug the intake with a rubber cap so there is no vacum leak?
@@pietsee1000 I am the owner that installed the clear catch can. Your fix is a bad idea. The manufacturer of the vented cap, CFM Performance, has stated it should not be used unless both the engine and cap are at full operating temps as they are in Florida and have never tested it in freezing conditions. Furthermore they have never tested it on this engine an it was designed for off-street, high performance, boosted applications, it is illegal in CA to sell, and it will fail an emissions inspection. All one has to do is install a flexible tube and replace the hard plastic tube, and I recommend a drain tube on the resevoir or a catch can.
@@alhavana9426 Put the catch can in between the camshaft cover fitting and the port on the fresh air side of the intake plenum. Basically replace the hard tube. The catch can can mounted on the left side near the radiator hose. The input side should drain downward to the cover and the output going to the intake plenum should slope downward to the catch can. On cold, high humidity driving on the highway is where you will most of the build-up due to the low vacuuum in the engine under load. Need to check it at each fuel up, so I opted for a clear catch can.
I plugged the air box and ran a hose from the valve cover to the atmosphere after the extended warranty ran out. I will never by a GM vehicle again.
Good to hear you took some preventive measures
@@NoNonsenseKnowHow I didn't really want to do this but GM now recommends an oil cap that is basically a pop off valve that vents in case the pressure gets too high in the crank case. So much for EPA specs. Good video.
@@deere3321 What is the part number for oil cap that GM recommends for the 2.4L Ecotec engine. Plugging the air box is a bad idea as you are defeating half the PCV system, and venting to atmosphere will cause an air leak and make the car run lean and cause even more problems.
These are just junk engines.
Yep. GM has never made a good 4 cyl. Now they're putting one in the new trucks.
Seem like Chevy is junk! So done!!!
@@deere3321 The Cavalier 2.2 OHV was a good engine.
So are the 15' and newer equinox's good?
Im not sure honestly. I would think that they have corrected the issue
Nope, this exact issue just happened to my mom's 2017 Equinox with 60k on it. Blew the rear seal out. In MN
@@Pastroodle sorry to hear that! Thanks for adding the info.
chad Spidle are u kidding? I guess some people want to get burned
@@mikecastellon4545
I don't want to get burned. I'm just curious if they fixed the issues because there are quite a few for sale.
I own a 2014 equinox. Biggest piece of junk ever created. Nothing but a money pit. Fix one thing another breaks. Fix that one and wouldnt you know it, another. Take my advice and get rid of it!!!
I like Chevy but yes that model is a piece of shit...for a SUV model style go with a Subaru or even a Toyota. For a full size truck , Chevy all the way.
@@lowlifeangleranything with an ecotech is garbage lol
Just happened to my Captiva 2012.. Totally screwed up my engine.. Full of sludge..
Sorry to hear! Let me know what you end up doing and how you make out
@@NoNonsenseKnowHow well..I just noticed a slight leak.. Took it to a local mechanic.. A good one.. The agency wud have raped me.. Rigged out the engine to check.. Found crankcase gasket leaking.. Opened the valve cover.. And surprise.. Full of sludge thick.. Now recommended to strip down the full engine... Clean.. And box up.. Will update u if I find any more surprises.. Not yet stripped down.. And ya.. The piston rings not available in Qatar here.. Fingers crossed
Can I clean the pcv myself with Wd40??
@@vinayakchipkar9249 well it sounds like you've got it at the right shop! I'm not sure how well WD40 would work for cleaning that. But it should help cut the grease yeah. Over here where I live you can find these engines at salvage yards for as little as $500 with a 6 month warranty out of wrecked vehicles. That would be the way I would go if the engine was toast. I guess that's not really an option in your country...
@@NoNonsenseKnowHow . Tat wud be an expensive option.. Coz American engines are not so popular here.. Well.. If it was a Nissan.. Honda or a Toyota.. U can get anything.. Let's see.. Hoping for the best
How to delete the pcv?
el gran de redesign the whole system. Not something that can be done on this vehicle. The redesign will have to be at factory on the next generation units. Do you still have yours? 3/20/19. I see your post is a year ago
Watch "2013 Chevy Equinox 2.4L PCV Modiification" on CZcams
czcams.com/video/ev_YJE72yw4/video.html
Dang. I have 2.2 L Ecotech. Supposed to be not as reliable. Darn.
Job security.
I've got a high horse power ecotec and let me tell you the PCV system is a fucking giant failure from GM . Some models come with a vacuum pump (LDK) that operated off the exhaust cam shaft. That's for emissions but the reality is they know turbo cars have massive blow by and it protects the engine from blowing seals.. That's my 2 cents.
