Title: Oil leak.
Post by: imprezzaworks on April 03, 2022, 09:57:33 am

When the guys were doing the tracking they showed me on the drivers side of the car the undetray with oil on. Going to investigate it more this week but any common areas above there?. I'm guessing a weak pipe, hopefully.

Assuming you have a short undertray, I would think boost pipe seal.

if it's just the seal its easy, but could be the bayonet fitting working loose from wear, either new same type of hose or upgrade

Lower boost hose was the issue. A hole in the metal coupling
