Crankcase (pcv) problems of the 2013 Chevrolet Equinox - part 2

Pcv valve freezes and blows engine main seal along with high pressure fuel regulator putting fuel in the oil, gm will repair some 2. 4 engines but not all but the issues is happening to all 2. 4 engines we the consumers need help in getting this issue resolved corporate America at its finest.

My vehicle displayed the issue covered under gm service bulletin - special coverage 14882 special coverage adjustment � plugged pcv orifice in intake manifold. My vehicle matches the criteria indicated on the bulletin but my specific VIN is not included in this service bulletin. My vehicle was inside the extended coverage of 10/120 indicated in the bulletin. Dealership indicated that the damage to my engine was caused by this defect but that the coverage did not apply to my specific VIN. Vehicle was started after work and was louder than normal so I proceeded to the closest dealership. The vehicle was luckily on a city street in motion when check engine light displayed. As I was insight of the dealership I pulled into the lot and the oil pressure and stop engine lights displayed the engine stopped running and power was lost to the vehicle at the service bay door. Car was brought into service immediately. Damage to vehicle in excess of $2600.

On 12/25/2017 my engine failed at 60 mph on the highway. I was almost re-ended by the vehicle behind me due to the rapid deceleration of my vehicle but managed to safely pull to the side of the highway where we waited for roadside assistance in -20 windchills. The engine failure was caused by a frozen pcv valve orifice which pressurized the crankcase and blew the main seal. After replacing the main seal it was discovered that the engine was damaged beyond repair and had to be replaced at my expense. My vehicle engine and year matches the group covered by special service adjustment 14882 but my VIN, like so many listed on this site, was not included in the special coverage despite the fact that my engine failure was due to the exact defect defined in bulletin 14882.

The contact owns a 2013 Chevrolet Equinox. While driving various speeds, a rattling noise could be heard coming from the engine. There were no warning indicators illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with a clog positive crank case ventilation and the oil seals, manifold, and pcv valve needed replacement. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 100,000.

2. 4l eco tech engines have a design flaw which is described in service bulletin no. : 14882 and apparently this bulletin was only sent to some owners but not all owners and the issue is the pcv orfice gets plugged with ice in the winter causing pressure to build in the engine which in turn causes the rear main seal to fail on the engine. Even though my Equinox had this 2. 4l ecotech engine and I did all the required maintenance as required gm failed to send me this notice (which they told me that did not send it to me since I did not have an eco tech which I did) but they also extended the warranty to fix it until 10 years or 120,000 miles and mine failed at 4 years and 125,000 so of course they have refused to fix or reimburse me for my out of pocket costs for something that could have been prevented if I would have been told about it. Also my truck just lost power as I was driving and this could have cause a huge safety issue if I had been on a busy freeway at the time. I was driving on a county road at the time just before entering a freeway when this failure happened. If I would have been sent the service bulletin I could have prevented a total engine failure by having the issue looked at and dealt with prior to this incident .

Oil consumption issue a quart of oil has to be added to the car once a week according to a Chevrolet service bulletin, the most common cause is stuck oil control rings. Generally the stuck oil control rings are the result of excessive oil on the cylinder walls and this excessive oil can come from the pcv system and/or the afm pressure relief valve in the oil pan.
