2:00 - THE BEST description of oil burning issue with these engines. THANK YOU!!!
2:52 - So that's where the oil comes from!
WOW! I nominate you for BEST instrustional and informational video of all time! So very well done sir!!!
Thank you guys for making such informational videos! I have to figure out how to fix my Prius and this is helping me wrap my head around it
Excellent - thank you for explaining the problem with that engine and now I know what to look for with purchasing a second hand CT200 .
Great job! Cleanliness next to Godliness. Very professionally done. U can do it blindfolded. 👍
Good to see you guys are now serving Tampa. That’s were I’m at.
The best guidance.... Awesome job done... I think what more details one can cover.... 👍
Looking to watch the next and continue video 👍🏻
Great video. Now I understand what goes on with that there engine.
Excellent attention to detail and service, on CZcams alone as well, you provide. Very much appreciated you keep these blocks and more from being scrap. I'm in SW Michigan and if wasn't on a pension, I'd be all about a nice thorough rebuild on my ~260K 2013 1.8L. For now, learning about what can be performed when the next 40-50% sale is at the salvage yard and I'm bringing home an engine to rebuild on my own. Then again... will have to look into the pricing and plan for worse situation scenarios budget projection. Looks like you come out to the Chicagoland area and SW Mi is only about an hour away.
I don't like this. Once you go as deep as he does, you almost might as well overhaul the engine, which costs almost as much as a new engine, so this is well beyond a maintenance procedure. So the first thing that is a maintenance procedure is checking the EGR system and cleaning it if it is clogged, and doing this in the car. This video does not go over that. The second maintenance item is unsticking oil rings without removing pistons. This is at least sometimes possible with detergent soaks or oil flushes on other engines, but I am unclear on the procedure for either on a Prius.
It seems to me like use of detergent fuels and oils should be able to prevent this, however he also showed us head gasket issues that to prevent, might require us to devise a head bolt retorquing spec; since modern head bolt torquing specs do not work for retorquing.
I actually don't buy his PCV sucking oil explanation either. PCV valves are designed to reduce flow when under high vacuum and so not suck oil under any vacuum that would allow the engine to not stall. The oil ring sticking is caused by inadequate oil and fuel detergency, not even by a clogged PVC system, though inadequate fuel detergency might cause that as well.
I just switched my friends Prius to high mileage motor oil at 120k miles, and we have always used Top Tier detergent gasoline, but maybe we should add even more detergent than that. to prevent both EGR soot buildup and oil ring sticking; as this engine may be more vulnerable than most. The problem is that too much detergent in motor oil can mean less lubricant.
@@alan6832 My understanding is when the PCV Valve is stuck, open. I know in my situation, the PCV Valve was stuck. I didn't check to see if open or closed at the time. Definitely didn't have an internal valve moving freely.
I recently switched to Mobile 1 0W-20 full synthetic thinking I'd try that for topping the oil to see if helps unstick the oil seal rings. Seemed to reduce the oil consumption significantly.
However, most recently, I ran two full tanks each having a bottle of Techron through. That coupled with the PCV Valve stuck open and an engine oil overfill situation that I didn't drain, I'm guessing caused my first misfire situations enough to trigger the check engine light. I made some bad videos documenting my situation. I swapped in a clean intake manifold, new PCV Valve, cleaned PCV Valve hose and cleaned EGR Pipe. I also cleaned the inside of the EGR Valve housing and valve from the bottom. I didn't yet get into the top side to check for the ski rutt in the plastic and thoroughly clean the rest.
I do need to clean the rest of the EGR Valve and EGR Cooler next as I'm getting a situation where when the AC is on and the HV battery is low, my temp goes from approx 194 to approx 204 and when at low speed and slow acceleration I get a rattling like noise that isn't the exact same as the starting high condensation cold engine type situation or what sounds like a really brief death rattle.
In regards to the oil, I was thinking running Amsoil for a few oil changes. However, the Mobile 1 seemed to do the job and I'll see if the Techron aided as well possibly.
B12 Chemtool soaking reads like about the only other methods I've come across as a potential solution beside disassembly and either cleaning or replacing parts.
@@alan6832 Sure, make sense. I've not used any oil additives yet. Always 0W20 Toyota full synthetic or Mobile 1 0W20 full synthetic 10,000 or more recently to top off the 20,000 mile. I also use only Top Tier 87 octane almost entirely and only a few exceptions.
I also had the overfill situation and was parked on inclines which I think might have caused a little more oil to get into the intake more than usual to cause the misfires. Hopefully, didn't cause any connecting rod damage. I'm at approx 283K miles, so scary.
@@jafinch78 My understanding is that high mileage oil has more detergents than oil formulated for new cars, while keeping the API certification that is lost with additives; and there are multiple brands of both types. Then if willing to lose API certification, Marvel Mystery Oil and Sea Foam both say they can be mixed with oil, but it is probably safer to mix them with gasoline.
Well done. I learned a lot.
Not related to this particular video, but you guys are the gasket masters. I have a timing chain cover that is ready to go back on, but the access to the engine is so small that I don't know how I'm going to get it back in there without smearing the RTV on other parts. I'm trying to jack up the engine to get a little more space. Is it ever a good idea to apply RTV on the engine side instead of the cover side?
You are awesome! Great video!
Guy you are good at what you do.
Amazing explanation 👏
Walter you are the best ,,, I totally recommend Walter and Jack to take care of you prius
Faraj
Excellent job I love it❤
Thank you !, torque of upper oil pan bolts is 15ft/lbs - 21NM, not 22ft/lbs according to the service manual I have though
Hi! Thanks so much for your videos!! Do you have a recommendation for a shop in the Washington DC area? Had the dealer replace EGR valve, but then the check engine light went back on and the same engine noise started again. Dealer says it’s the head gasket… looking for another opinion/ recommendation for a local shop
I’m near Raleigh NC and would love for you guys to come fix our 2013 Toyota Prius, we are having this issue now and the car has 187,500 miles.
Would you replace crankshaft bearings that have polished spots? Like not through the aluminum, just polished through the machined lines on the bearings.
Thank you. I wanted to how exactly EGR works.
My car was also burning oil. I found on internet to replace PCV Valve so I replaced, seems to be working fine. Recently I got the EGR Code. I’ll have to clean that now.
Does your car vibrate while driving when you receive an EGR valve code?
@@HuyTran-no8nd : no not at all. The light comes on. Stays for few days or week then. Turns back on. I think. EGR. Kicks in at a certain temperature to cool off emission gases….
@@bizforall My Toyota Prius burned oil, causing the car to make noise and little feeling of vibration when driving. Try checking the egr valve and intake manifold.btw thanks for sharing this information
I can't find the follow up video and how did you break in the engine rings
What brand rings, bearings, and gaskets do you recommend?
This is not me asking for a quote from you, but In general, how much would this job cost, and if the egr is clogged and I clear it, is it possible this just goes away without needing a full rebuild like this?
Hello just wondering in a situation like this no machine shop work will be required?
Do I must do head resurfaced? What if not?
Where do I get that done. As individual DYI that’s only thing bugging me.
Did they replace those main bearings or did they reuse the old ones
Wow this was pretty cool...how much do I need to save up for an overhaul like this?
It should be possible to free stuck oil rings in place by soaking them in soot cutting detergent in place, without engine disassembly, though beware of hydro lock when doing so. it should also be possible to clean the EGR or PVC passages without much disassembly. Head gasket issues are usually an argument for periodic retorquing of head bolts. This takes some disassembly and retorquing specs, which for modern engines, have to be devised as the factory torque specs don't work for retorquing with modern head bolts.
Awesome video bud!! I bet you can disassemble and reassemble these engines with your eyes closed closed and one hand tied behind your back lol 😂
Is this problem still goes on even with the 2019 corolla 1.8 hybrid?
Hello guys
I tried toi rebuilt this engine but i failed.
When i was putting cranshaft from the other engine , it was bloqued.
Can we put a old cranshaft from an other engine ? And how do we chose the caps?
Thanks for yours reply
Thank you for this!
Would this be part of routine maintenance at a Toyota or Lexus dealership?
I have a new used 1 previous owner 2011 CT200h with 103k miles and plan to keep her to 250k.
Would you recommend all this for 100k precautionary service?
I need a mechanic like you in Austin!
No, the dealer won't do it, but you shouldn't need to worry until it reaches 150k. I'm in Austin too and I have one with 165k on it. I'm also looking for a hybrid mechanic who can do this kind of work. Let me know if you have someone from your research! Thank you.
I have never seen honing done like that before! You need to get the home angle correct or you will affect oil consumption
So what about my 2008 why does it consume oil? It does not have an egr
Does the gen 4 Prius suffer from oil issues
Thanks for teardown. No surprise, today's open deck aluminum blocks don't support head gasket very well. There is a reason that truck engine blocks still use a close deck iron block. Hybrid saved a lot of fuel, but long term cost may be the same because of aluminum engine replacement.
Sweet and here I thought it was strictly due to piston rings .
After start all rings will spin freely different directions...
Do you think putting the pedal to the metal to merge onto the freeway and driving mostly on the freeway will help combat this problem? Because it seems oil starvation and that vaccum problem only happens at low throttle. Anyone care to chime in?
This is false information
"This one will no longer consume oil" ....yeah until it hits 100k again with infrequent oil changes and hard driving. Putting the original part rings back in is just a bandaid for future oil burning unfortunately. Upgrade to revised rings from 2015+ Prius'..
Where are you located ?
I have a 2014 CT-200H with 85K miles. No motor issues yet but is there any preemptive maintenance i can do to avoid all this? I love the car and plan on keeping it forever or until i total it.
Yes- Keep the EGR cooler and lines clean, and clean the intake manifold as well- every 60k-90k should do, as these parts all foul up with carbon quickly.
Check out priuschat Gen3 section for many helpful forum links that talk about EGR and other maintenance.
Just perform your scheduled maintenance on time or early. For example, Lexus says to replace your spark plugs around 120k but I changed them at 110k and looked really worn. Also at 100k change your coolant of the radiator and hybrid system and your cvt fluid. I'm at 145k miles on my 2015 CT and haven't cleaned the egr system yet but will soon
@@aminort2 this is the correct answer, along with schedule handbook maintenance
Exactly
AMSOil 10W30 Signature Series Oil,With more Frequently Change Intervals Will Prevent these Problems. And Keep those Valves Cleaned With CRC Valve Cleaner Frequently. Good To Go.
Do you beplace the old crunchcraft bearings or used old ?
New. They are cheap so might as well use new.
@@gasketmasters how do they typically do on specs? Do you typically run standard size or have to adjust ring or bearing sizes?
@@ryanfinch81 just standard size when honing
@@gasketmasters is there a brand you like more than otheres?
What's a job like this cost?
That's a full engine rebuild, probably 7k-12k with parts and labor.
7-12k is a whole new vehicle. An engine rebuild cost around 2500-4000 just depending on what you're rebuilding
a working egr and an oil catch can
I have an 05 Prius that is burning oil. Could I just monitor and make sure i have oil to put in the engine? Also, at what point does your oil pressure signal you on your dash?
I have a 2010 Prius burning oil. I’ve been monitoring the oil for a while and not once have I seen the oil light come on and I’ve had the oil get pretty low. I use my car for Uber and I can’t afford the time to take the engine out for a rebuild. so I got a engine at the pull-a-part for 260$ and plan to rebuild it with just new head gasket, head bolts, piston rings and rod bearings under 200$. Better than a 1600$ engine off the shelf from s&w with 160k miles on it
@@christophertatem8790damn why did the junkyard sell you an engine so cheap?
I’m in Atlanta Georgia and my local junkyard called pull a part sells a four cylinder engine for that price.
@christophertatem8790 you have to take it out yourself? Do you have to bring an engine hoist?
@@Hallahanify yes you have to inspect it so you know what you are getting and then remove it yourself and they provide engine hoists
my old Prius has 223k... this looks extensive, I think ill just keep adding oil to it for a few bucks.
Awesome video as always! Had a quick question for you
Do you guys know why the prius has a tendency to do that short rattling sound on acceleration from a stop (Most common when driving and you come to a stop at a sign or a light)? Is it related to this EGR system by any chance?
Thanks!
Clogged up intake manifold
@@repairvehicle Have had the intake manifold off / cleaned it quite thoroughly. Still does it
@@SidewaysGts , did you clean it yourself?
Use higher octane gas 89 or 91 don’t use 87 and it will go away
@@santosf1107 don’t do this, use the fuel the car is built for
Do you guys work on Toyota Hybrid Transmissions?
Did you forgot to change atf?
@@repairvehicle No. My car won't start. The electric motor or however it starts went bad all of a sudden.
@@davidgriffin14 did you ever replace your atf?
@@repairvehicle I did about a year ago.
@@davidgriffin14 first time in how many miles? Previous car was in accident?
Hello sir i have a 2012 prius with 206.000 kilometers on it. I ask my local toyota dealer in the Netherlands if they also check the EGR. They said yes. But someone told me that the toyota dealer only check fault codes from the EGR. And that i need to clean it myself. But i’m not that handy! And i don’t dear to take things apart from my car. What’s the best way to krep the problems away?
Unplug the egr now you won't have to worry about it but will get a warning light on the dash
I PUT ON A OIL CATCH . I moved the PCV, I screwed it into the out of the catch can, I drilled a hole in the bottom of the catch can and put a drain tube so when I change the oil I can drain it
👍🏻⭐️
Can you do an EGR delete on the 2nd gen prius?
Want to come back to Ohio and do mine? I am still working on the Cylinder Head and lapping my valves. I was hoping changing the location of the PCV valve to a more vertical position on its way to an oil catch can would solve my oil burning issue. What let’s one know they need to go this far? Is there an oil burning threshold or something?
Brand of oil and frequency of oil change
@@repairvehicle I would say sadly I listened to the marketing hype... I would buy the most expensive synthetic oil I could find and only change it 1 time a year... About 15,000 mile intervals. This past year I am doing 6 month/ 5,000 mile intervals with the cheapest oil I can find which happens to be Costco Kirkland brand full synthetic oil.
@@nathanhood8578 , every brand of motor oil has different evaporation rate at which oil evaporates and causes oil consumption.
@@repairvehicle that's great and all, but that evaporation rate isn't stated on the bottle. What is stated is what the oil is supposed to be rated for.... Like annual oil changes and mileage it's supposed to last. Mobile1 oil listed as annual oil stated it would last for 20,000 miles which I never hit.
@@nathanhood8578 , there is a lot information not stated on the bottle, majority of oil companies don’t want you to know the facts. You have look for this information at companies website. If you read small text on Mobil 1 bottle, oil cannot last 20k miles and should not be used for 20k miles. It’s just marketing words to trick people to believe in false information. Also, Mobil 1 will never tell you that their full synthetic oil is not even synthetic. It’s labeled as full synthetic but it’s not synthetic at all. Late 90s there was lawsuit between Mobil and castrol oil about using none synthetic base stock in oil but keeping the label. Mobil lost lawsuit and since then every full synthetic oil on the market is no longer true synthetic.
If I am allowed to give you a million thumbs up on this video, I will doit. Well said. 👍 X1,000,000 lol😅😅😊
first
I have a 2011 CT that needs this work done, how much?
It’s cheaper to buy low mileage jdm engine
Nobody going to measure clearance of the cylinder, if the shape is ellipse. Red nek repair.
The PCV is a bigger culprit than exhaust gas choking up the small openings in the intake manifold. Just replace the PCV every 50,000 miles or so. Don’t even need to waste money on a catch can. PCV cost less than $10
