Why would oil be leaking from a blow off valve?
i own a 05′ gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out….. why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently….
what kind of turbo r u using? it its one that has pistons the oil is leaking past the compression rings – which would also mean you are loosing compression. the problem is not really serious
ask on VWvortex. theyll know much better than us.
And go diverter valve like its designed to. Your car will perform and run much better.
there is probably a problem with the oil lines that bring the oil from the block to the turbo. It seems like that could be a bad problem, so u should have it checked out.
