SUMMARY:
CHEVROLET: OIL WILL BE FORCED OUT OF PCV INTO INDUCTION SYSTEM IF NOT PROPERLY CHECKED FOR OVERFILLED AND ALSO AGGRESSIVE DRIVING, WITH LOW MILES, CAN PUSH OIL THROUGH PCV SYSTEM. MODEL 2014-15 CORVETTE. *PE

This is the first indication I have seen that GM recognizes that this is a problem. It will be interesting to see what is suggested as a possible fix in regard to the aggressive driving component of the issue.

This is not a new service bulletin. It was published internally on NOVEMBER 01, 2014 according to Chevrolet Problems, Complaints, Recalls and Investigations. In fact several of our members early on in the discussion of this issue posted that they were told specifically the wording of the bulletin when they took their C7s in.

That is because a PIP is GM speak for preliminary information which is an unpublished bulletin, only available to GM service personnel. In this case since the internal publication back in November of 2014 apparently the final decision was not to follow up with a Service Bulletin.

This preliminary GM notice was to alert service personnel about overfilling with oil. GM has reduced the amount of oil recommended for re-filling after an oil and filter change.

Additionally, GM redesigned part of the air intake system to reduce chances of oil entering into the motor from the air intake side. This was acknowledged by one of the most constructively-critical members of the forum, Tracy from RX; he noted there was huge improvement in this area and that GM consequently reduced the amount and likelihood of reduced oil getting back into the air filter, MAF and related.
