destey Posted January 25, 2012 Share Posted January 25, 2012 1997 Subaru Legacy GT 2.5. I'm seeing oil residue at the bottom of my motor, trace it back to the hose that goes up to the IAC valve. Any idea why there would be oil here? Did I overfill it when I changed the oil? Thanks! Link to comment Share on other sites More sharing options...
destey Posted January 26, 2012 Author Share Posted January 26, 2012 Not overfilled with oil, I checked the dipstick after sitting on flat ground overnight. Head gasket was done about 50k miles ago, so I don't think its that. Any ideas? Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 27, 2012 Share Posted January 27, 2012 PCV valve is clogged and oil vapor is pushing up through the breather hoses into the air intake tube. That would be my guess. Link to comment Share on other sites More sharing options...
destey Posted January 27, 2012 Author Share Posted January 27, 2012 Thanks! That sounds like about as easy of fix as there can be Link to comment Share on other sites More sharing options...
