I have had my procharger on for about 1000 miles at 10-11 psi, some hard, most easy. Anyway, I put an open breather on it to keep the oil out of the intake tract and I have been finding oil on the intake near where I mounted it. I put a check valve on the pcv to see if that would help and it didnt seem to make a difference. It seems to do it more at startup than any other time, and when I pull the hose it does puff a little, and intermitantly. You guys think it is blow-by? I may try my catch can on that side to see what it gets. Any input?

 

Had the same problem on my truck (oil in the intake tract) so I made a catch tank to seperate the oil in the blowby. Now the intake is clean and dry when inspected. No check valve either.

The problem actually went away. The check valve was stuck. I took it apart and cleaned it, no more problem.

 

did you just hook up a little breather on the line coming from the passenger side valve cover?

 

Yep.
