A buddy has a 2009 with the 2.4. He wants to tear it apart as something has caused a no compression on one cylinder. (Guess I will be helping him-he has nothing to lose now) So far he has not blown the rear main seal, not yet. But has had some issues with oil blowing out that PCV system. I think t is a different system without a actual PCV valve.
Yeah, there is just a little orifice hole on the backside of the intake for the PCV system, and when it stops up, it will blow out the rear main seal, I have seen the two for spit out the rocker arms before causing no compression
@@lakesautomotivediagnostics6509 Interesting! We will be looking at it soon. The vehicle has been sitting in a snow bank for the last couple months. We have had some -30F & -40F here. My little garage is not usually heated & floor is not heated to not the best conditions to work in. Good thing this is just a hobby!
So wouldn't the prudent thing to do is clear the pcv and run the engine to see if the seal is actually toast before replacing it? The seal is rubber and runs on a smooth surface as you know, the pressure pushes the seal and it loses contact with the surface. It actually doesn't mean that the seal is ruined. Test first so that the customer isn't saddled with a huge bill that may have been unnecessary.
They have a warranty, customer is not paying out-of-pocket. and this is the 2.4 L. It does not have a traditional PCV valve. It has a small orifice hole in the intake .
I believe the rear main seal replacement is 10.8 hours and I believe the intake replacement is 2.3 hours. regular oil changes will help but it seems like eventually this will happen to every 2.4 L due to carbon buildup if you pull the PCV hose off of the air cleaner duct and you have water or condensation buildup in there then you need to pull your intake, manifold off and clean out your PCV Oirfice hole and the holes that go to each port on the intake to prevent your rear main seal from blowing out. There are videos out there of people adding a external PCV. But I have never done it.
On the rear, main seal or the intake, you have to pull the engine or transmission out to do the rear main seal, I do have one coming up on the schedule next week. What exactly are you wanting the video on and I will do one.
@@AlvGto I get mine back today, my daughter works for a GM dealer so I get good discount but still I don't want to have to have it fixed every tie it gets cold. I'd sell it but IDK what I'd buy to replace it.
Make sure they took the intake off and cleaned out the PCV orifice hole and they sell a vented oil cap on Amazon part number FC219 that Vents at 2-3 pounds of crank case pressure to help from blowing out the rear main seal
Just had my rear seal blown out and pumped all the oil out last week on coldest day 2024. 2017 Equinox. Dealer won’t help. Extended warranty won’t help. Say they don’t cover “water intrusion”. Paid $2,999 for the extended warrantee. Thanks a lot GM. Will NEVER buy ANYTHING from them again! Not impressed.
I am doing a rear main seal tomorrow on a 17 equinox that blew out during the cold also they had a aftermarket warranty, and they are covering it, I would not call it water intrusion. I’m in the aftermarket world so I do not know how the extended dealership warranty works but if I was you, I would probably try a different dealership and see if they can get it pushed through.
@@lakesautomotivediagnostics6509 Ok. Thanks! I’m sorry if I miss worded my comment. The extended warranty is called Service Contract and is not part of GM it was sold to us through the GM dealership when we bought the car used. Car was a 2017 Equinox bought in 2021. I’m not sure how a different dealership could help? I do feel that our dealership did nothing to help but I could be wrong. Do you still think we should try another dealer? We feel very cheated.
@lembriggs1075 maybe try to find a independent shop that does warranty work for the warranty company that you have and see if they can get it pushed through or even call the company yourself and give them hell. I hope you can get someone to help you.
@@lakesautomotivediagnostics6509 Thank you! I’ve already called the warranty company and they reviewed it again, they are the ones calling it a water intrusion and telling me that it’s a known fact that this is caused by cold weather and they are being very stern that they will not cover a new engine, or the timing chain/rear seal replacement. They said we need to pay out of pocket and have it documented and sent to them to verify otherwise any future engine breakdown would also not by covered. They sent a rep to look at it and he somehow determined there was ice blocking the PCV that caused the real seal and motor oil to exit. I will check tomorrow to see if any other shops would go to bat for us. We are in North Central Indiana.
It is a known problem with the 2.4 L the way the PCV system is designed is faulty, and the condensation from inside of the engine will freeze in the PCV tube during cold weather and cause excessive crank case pressure, I just learned today because of the 2017 that I will be doing tomorrow That they make a aftermarket oil cap that has a PCV built into it to let the crank pressure out at 2 to 3 pounds
