Just got back from the dealer with news that my 2017 Malibu 90K has a PCV issue.
I have a leak from the crankcase caused by the high pressure. They ran a cylinder test and there are no issues with the pistons or rings. The dealer quote to replace the orifice is just under 2K.
How difficult is this job? Can my basic mechanic handle this?
The internet is a dangerous -- I found a Service Bulletin 20-NA-047 descrbing the issue and it seems straight forward?
The service advisor was stunned that I've been driving the car with this condition for about a year. Is it that bad?
I wonder if these PCV clogging issues are related to using regular oils and not using full synthetic oils. Semi synth. is no better than regular oil BTW.
