Summary

14882 – Special Coverage. Certain vehicles equipped with a 2.4L engine (LAF, LEA or LUK) that have experienced high oil consumption may also experience a frozen and/or plugged PCV (positive crankcase ventilation) system during cold weather operation. This condition may increase crankcase pressure leading to a rear crankshaft seal oil leak. If the oil leak is ignored or not noticed, an engine clatter noise may be noticeable and/or the engine pressure warning light may illuminate. If this condition is not corrected, continued driving with engine noise and/or the engine oil pressure light illuminated may damage the engine. Dealers are to perform a crankcase pressure check, and if required, remove the intake manifold and clear the PCV orifice.

SERVICE PROCEDURE

Crankshaft Rear Oil Seal Replacement

Determine if the crankshaft rear oil seal requires replacement.

If the crankshaft rear oil seal does NOT require replacement, no further action is required. This bulletin provides coverage for replacing the crankshaft rear oil seal, performing a positive crankcase ventilation (PCV) pressure test and, if necessary, unplugging the PCV system.

If the crankshaft rear oil seal requires replacement, Refer to Crankshaft Rear Oil Seal Replacement in SI. Proceed to Positive Crankcase Ventilation (PCV) Pressure Test in this bulletin AFTER replacing the crankshaft rear oil seal replacement.
Positive Crankcase Ventilation (PCV) Pressure Test

Special Tools

EN 23951 Valve Manometer

2.4L Ecotec Engine — LAF, LEA, LUK

1. Disconnect positive crankcase ventilation (PCV) hose at the air box (1).

2. Install EN 23951 valve manometer into fresh air line.

3. Start the vehicle and let the vehicle idle. Observe if there is positive or negative pressure on the manometer gauge.

Note: With a properly operating PCV system and the manometer installed, there may be a whistle noise coming from the front or rear of the engine when the engine RPM is raised. This is normal when the vacuum in the engine is increased. The front /rear seal will open up and let air pass, which produces the whistle noise.

4. Increase engine RPM to 1500 RPM for 2-3 seconds. Determine if there is positive or negative pressure on the manometer gauge.

If the manometer gauge indicates zero or positive pressure when the engine RPM is raised, the PCV port in the intake manifold needs to be unplugged. Proceed to step 5.

If the manometer gauge indicates negative pressure, the PCV system is NOT clogged. Reinstall the positive crankcase ventilation (PCV) hose at the air box (1). No further action is required.

5. Remove the intake manifold. Refer to Intake Manifold Replacement in SI.

6. Clean ice, sludge, water, and carbon out of the PCV pipes, hoses, the PCV nipple on the cam cover, the PCV orifice between the number 2 and number 3 intake runners, PCV orifice (1) in the cylinder head (use a 1/16 in drill bit as shown in photograph) and the throttle body. Refer to photographs. Also inspect the related PCV hoses and connections for potential damage.

7. Install the intake manifold. Refer to Intake Manifold Replacement in SI.

  1. 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!

  2. I’ve had a similar situation to everyone else. I recently bought a used 2012 GMC Terrain, 97000 miles. This bulletin is not attached to the VIN, so I had no idea this could be a problem. Within 10 days of ownership, my engine fails due to the rear crankshaft seal blowing out and oil leaking. Take this to a repair shop, and they tell me that it was due to an iced up and plugged PVC orifice. Now I’m looking at a $2100 repair, which GMC and the dealership refuse to help with, even though my vehicle falls perfectly in line with this bulletin. I’m never buying a GM vehicle again.

  3. Is there a permanent fix for this. I had my rear seal blow out about a month ago and now everyday it’s cold out I’m afraid to drive my vehicle. It cost me $600 to replace the seal and there’s no way I can afford to pay that again.

  4. HMM, interesting. I had the same situation with my 2014 Chevy Equinox and my VIN isn’t covered either. We actually contacted GM and have someone named ‘Todd” working on our case.. He said that if enough people contact GM about the issue, that they may send out a new bulletin. Just by looking on the internet I can see that there are many people dealing with the same problem. SO FRUSTERATED!!!

  5. Same issue here. 2013 GMC Terrain. Rear main seal failed due to PVC system clogging/frozen. Called GM customer service, told “I can’t find the service bulletin 14882.” Miraculously the bulletin was found after I told the person I found it through Google. I was told “Your VIN isn’t attached to this service bulletin.” I asked “Why isn’t it?” He replied with “Only certain manufacturing cites are covered. But keep your receipts, because in the future your VIN might be attached to this bulletin, and you might be reimbursed” This is a design problem. The PCV system is poorly designed. A 1/16th inch hole is NOT sufficient to release the pressure of a running engine. It’s a manufacturers defect that GM expects it’s customers to cover. Why is it our responsibility when we didn’t design this engine? Regardless of how many miles, or how old the vehicle is, this should be covered by GM. These vehicles need to be recalled and replaced with other vehicles. I’ve already filed forms with the NHTSA, and the Better Business Bureau.

  6. A customer of mine nearly lost his engine when the rear main seal blew out. 107k. The PCV system on this 2.4 is a horrible design. Chevy is doing the repairs for free, minus diagnostic time.

  7. My 2013 Equinox had a complete engine failure caused by the exact issue defined in bulletin 14882. Despite the fact that my model year and engine type SHOULD be covered, my VIN was not part of the special service adjustment. My vehicle only had 81,000 miles on it and I ended up having to replace the engine.

    I noticed there are a MANY complaints on NHTSA regarding this EXACT problem yet GM refuses to correct the vehicle group included in coverage for this defect. I filed a complaint regarding my situation. Hopefully if enough people do the same maybe GM will be held accountable for this defect.

    I have been a GM customer for 35 years. This is the end of the line. My next vehicle will be from a different manufacturer.

    • I have a 2012 Equinox with the same issue and Chevy has denied any responsibility for this defect for our vehicle as well. I have also filed complaints. My family will not be purchasing form this manufacturer in the future.

  8. As the owner of a 2014 Equinox with this PCV/Main Rear Seal issue. I could not be more unhappy with the response that I have received from my local dealer. Ironically enough, I got my oil changed on 12/28/2017 and my car was fine. On my way home from work on 12/29/2017, the engine started making a weird noise and no sooner the oil pressure and turn off engine light came on. I immediately pulled into the gas station and turned off my vehicle. I had it towed to the Chevy dealership and they gave me a loaner and told me about the Special Coverage Adjustment and Service Alert. However, now they are saying that my engine won’t start and I have to pay them $375.00 just to run a compression test! They also said that they definitely see that the seal is broken but that there has to be another issue because the engine won’t start so it’s more than likely not covered! I call BS on this! My attorney will be in contact…rest assure.

    • Jaime Rogers, I just had a similar problem. Had my oil changed at a GMC Dealership for my 2012 GMC Terrain back in November of 2017. As of December 29, 2017 my vehicle purged all contents of oil all over my garage over the course of 1 night. Had my car towed to the dealership and was told the PCV froze over, causing my rear main seal to blow out due to high pressure. I was NOT allowed to see how/why this had happened and was NOT informed about the Special Coverage from Bulletin 14822 which is supposed to cover the repair. I had to ask about the coverage myself after much searching, after I was told I would have to pay $3200 for repairs.

  9. I have one of the 2011 Equinox’s that the PCV valve froze and in turn shoved a lot of the oil right out of the rear main seal. I am sick. This happened to me on the 6th of January and guess what mine has 125,000 miles so now GM won’t take care of it. The chevrolet dealer wants $10,750 to fix it. Really…the vehicle isn’t worth that much. Go figure so now I am without a vehicle.
