Just wanted to comment. I was using 2qts in about 7-800 miles after buying this thing used. Found your video. Performed the sea foam trick. It has used about 1/2 qt in about 1500miles. Much better. However, fuel is still mixing with oil. I only have 100k on a 2011. Selling this thing as soon as possible. I will never buy another GM product. Thanks for the help
I have a 2001 Malibu with 3100 engine. At 6,000 miles on engine oil, it has used 1.5 quart. I am please with oil consumption. Car has now 120,000 on engine. 😊
Sounds like the P0 171 is a oxygen sensor or map sensor, from what I understand the high pressure fuel pump has O-rings on the shaft, and when they leak, it will inject gas into the engine, that little piece or a little cylinder you pulled out is called a followerand it supposedly rubs on the camshaft, I have been told those followers can go bad too, it is recommended when you replace the high-pressure fuel pump to not only replace the high-pressure hard pipe but the follower also, not sure if this helps, hopefully I had answered your questions properly. Thanks.
Nicely done!! We have a 2013 Chevy Equinox with the one quart per fill up consumption. I confess, when you said you were going to put pistons and rings in it if it didn't work I was rooting for it not to work! Reason is, I thought if you did a video of it, it would be great to watch before I did mine. However, the sea foam looks like it solved the problem. I didn't do the fill the cylinder thing, instead added 5 ounces of the high mileage seafoam to the oil as described on their website. DIY Dave seems to have had some success with it. After 300 miles I'll let you know how it did.
I have a 2008 Ford Escape that was using 1 qt of oil in 100 miles. I pulled off the PCV hose and sprayed brake cleaner in it. Started the engine held my finger over the intake port that the PVC hose went on run it some shut it off and sprayed more in let it set about 5 minutes each time. Hooked back up the PVC hose and run it. Doesn't use any oil now. After 200 miles it is still on the full mark.
I like that idea! Still working? I should have added brake cleaner to the cylinders with the seafoam! I'm down 1 quart @4800 miles and changing the oil today.
After 4 month it started going down a little so I did the brake cleaner again. Will see what happens. If it stops going down I will change out the PCV valve. @@ryanl6722
Majority of our issues stemmed from fuel in the oil from a high pressure fuel pump and camshaft follower issue. It was still running and not throwing any codes but had a slight stumble on startup and fuel in the oil. I replaced the HPFP and follower and for good measure added seafoam and the oil usage has dropped considerably. The fuel in the oil seemed to be a contributing factor.
I've got the same issue with a customers equinox just eating oil. But he brought it to me because of the check engine light was on. Catalyst insufficient code PO420. Found out that it had a random misfire. Plugs have been burning oil. Blow by is terrible. He wants to unload the car, I told him to give a couple of days with it, and I believe that he will like the results. Only has 127K miles on it. No need to check the cylinder leak down. I know it's bad. Hopefully we can get the cat cleaned out too
@@ryanl6722 so far it has decreased the oil consumption quite a bit. We're going to do a second Sea Foam soaking of the rings. Also I'll pull the intake to give the PCV port a proper cleaning and I can see that it is actually clear.
@@itsnitz0575 They decided to trade the car in. Not sure how big of a hit they took. I had planned to do a cylinder cleansing and pull the intake to clean the PVC passages. GM has another engine issue and customers have to live with it.
Take a look at your front crank shaft timing/harmonic wheel. Oil could be leaking slowly from the seal and you would not know it. If you see oil coming from the crank shaft then you should replace the seal.
short socket on the crank bolt with a long braker bar. it's not easy. looking back on it, it might be easier to remove the passenger front wheel and lift up the plastic finder well. I did crank it to blow out the left-over Seafoam. just remember to cover the engine with rags or something to keep the hood clean!
Nope. the PCV was not plugged. An easy test for the PCV hole being blocked or not is at this link: czcams.com/video/knnQWAtp0ik/video.html . Much less oil. 1 quart down between oil changes. basically, I'm changing the oil when it needs a quart (at 4800 miles this time). I am also adding a 1/2 can if seafoam to the oil and driving 200 miles or so before the oil change to do more cleaning.
After it sat overnight, 90% of the seafoam went past the rings to the oil pan. The cylinders were basically empty, but I cranked the engine over to make sure I blew all the rest of it out the spark plug holes. I changed the oil to remove the seafoam from the oil pan.
@@ryanl6722 I’m trying to understand the process. I think I got it. PROCESS: → Fill spark plug holes with Seafoam → Create some movements to get Seafoam to creep in → Let it sit in there overnight to let Seafoam work its way down to the oil pan → Install spark plugs & all removed items → Change oil/oil filter → Start the engine & test drive it. It’s a great video BTW. I learn alot from it. Thank you for making this video. I bought a 2014 Chevy Equinox over a month ago, and now my wife starts to experience some problems such as stalling, lack of power, etc. I need to learn and tackle this thing when time comes.
@@salyleak1764 one thing, before re-installing the spark plugs, crank the engine to blow out the leftover seafoam. Cover the engine area with something so you don't have to clean off the bottom side of the hood and firewall. The fuel injectors are still pumping fuel in the cylinders.
@@ryanl6722GM has a flood clear mode, key on-floor it and hold-crank. Injectors will not activate and you have not only full flow from plug holes, but also intake to blow clear the holes.
I tried to place them all 1/2 way down because the issue is with the rings, and I figured the cylinder is shaped a bit like an egg by now and more seafoam would get to the rings there (and they needed to hold 1/2 of can)
I don’t think sea foam does anything to fix the consumption of oil. I have a Chevy captiva I changed every 3000 miles Winter is when I see more consumption than summer
Yep, and transmission!! GM should have come up with an engine cleaning process to do every 50K. We are doing oil changes every 4000 miles now and are at 130K miles BUT, I just replace the transmission with a used one because it died too! I don't think GM likes cars that go over 100K to be still on the road! Good thing I do my own work!
I just did a leak down test today on a 2010 Equinox and I played hell to get the sweet spot for maximum pressure to build up. It's tricky to get the piston in the correct position but it's a limited window. I had my tech watch the gauges while I moved the crank with a long ratchet to where it had max pressure build up. My point is that it's a limited crank position where it's sealed all the way. How I determined the correct angle was to put 20 psi into a cylinder and just after the crank stopped pushing the ratchet down and it loosens up and then go approximately 30`-40` more and I found this to be the best crank angle for max pressure. My 2 cents. This engine is burning about a quart every 300-400 miles, but leak down with 100 psi was only at 94-95 psi., which is strange to me. I just had the head machined due to the timing chain breaking. It broke 3 rockers and bent 4 valves. So I know my top end is good. I put a product called Engine Restorer in the oil and I'm going to run it for about 200 miles and see if it lessens consumption. Even if it lessens, I'll do the Seafoam thing.
Ya, I did not do the after-treatment leak down test because it was such a pain. I figure, if it's the oil ring that's gummed up, the leak down won't show it if the 2 top rings are good. I'm now at 3500 miles from the Seafoam treatment and I'm down 1/3 of a quart. I change the oil every 5000 miles so at this rate I'll be down about 1/2 quart between oil changes and I'm very happy with that!
@@ryanl6722 Apparently it's not that the oil rings get gummed up. They lose tension because of a terrible design. What's strange is that the exhaust isn't puffing blue. I remember seeing many Dodge Caravan's from the 80s and finding out that the ones with the Mitsubishi 2.6 were the ones that would smoke.

2011 Chevy Equinox 2.4l….forgot to add
I understand. Unfortunately, these engines need regular oil changes and if they overheat or ever run low in oil things go bad fast.

please with oil consumption. Car has now 120,000 on engine. 😊
If gasoline is mixing with the oil, one suspect is the high pressure fuel pump. Changing that worked for our 2.4LUK.
High pressure fuel pump will allow gas into the oil, shaft seal leaks, replace high pressure line if you do the pump, it connects to the pump
Sounds like the P0 171 is a oxygen sensor or map sensor, from what I understand the high pressure fuel pump has O-rings on the shaft, and when they leak, it will inject gas into the engine, that little piece or a little cylinder you pulled out is called a followerand it supposedly rubs on the camshaft, I have been told those followers can go bad too, it is recommended when you replace the high-pressure fuel pump to not only replace the high-pressure hard pipe but the follower also, not sure if this helps, hopefully I had answered your questions properly.

wow... you fixed it... good job!!!
Use 0w40 5w40 api sp c3 to reduce oil consumption. Fuel from pump makes 5w30. Api SP for gdi engines. Dexos bad for this engine. C3 for low soot
Take a look at your front crank shaft timing/harmonic wheel. Oil could be leaking slowly from the seal and you would not know it. If you see oil coming from the crank shaft then you should replace the seal.
no leaks on this one, was just blowby. Still running good with only 1 qt per oil change (~5000 miles)
how do you crank by hand on equinox? the second time you cranked it, did you do it by turning the keys ignition?

When soaking the cylinders does it matter what position the pistons are in

You put brake cleaner first to start the process?
no, but that is a good idea. that's cheaper than seafoam. Maybe mixing the two??
Sounds like my wife's car, it seem like I have to add oil ones a week.
give this a try. we are still only adding 1 qt between oil changes.
Any more recent updates?
I'll check the oil and milage tonight and post it for you.
