A clogged PCV nipple caused problems on my '94 850 (mainly a rear main seal leak, leak around oil fill cap causing oil under plug cover, etc.) I wanted to make sure that it did not happen to my '98 s70 turbo but after a brief inspection of the same area I could not locate it. I've read about the PCV on the S70 but can't locate it. Is it in a different location? Is it not on the Turbo? I must also add that I have no experience with a Turbo and just recently took over maintenance duties on this one as it is past the point where dealer service is an advantage.
On a seperate Turbo topic, when changing the O2 sensor I noticed quite a bit of oil gathered around the turbo. Is there a common source for this type of leak? Just trying to get some information before I investigate.
PCV on S70 turbo?
On your 850 and S70 there is an oil seperator no PVC but the '94 does have a flame trap which do get clogged along with the hose. Turbos do not have flame traps! The oil seperator is located under/behind the intake manifold.
