Bad PCV? 2020 STI
Been trying to diagnose slight smoke and burning oil smell coming from underneath the top mounted intercooler on my 2020 STI. Pulled the intercooler and it does indeed have some oil in it from both the turbo hose and the throttle body. Pulled the PCV Valve aswell and it does have some oil residue in the hoses connecting to the turbo. I did the shake test for the PCV and does rattle which kind of throws me off. Is it safe to say the pcv is failing or can it be another issue? Possibly turbo seals?
