i was wondering if anyone has ever had the problem with a vacuum pump pressurizing the crankcase causing excessive blow by and what was done to determine this as the problem on a 24 valve mine is really bad but havent lost any performance out of the engine runs great no smoke etc im opened to ideas here

did you ever locate your problem im having a simular problem

 

I thought I had excessive blow by but it turn out to be the seal between the powersteering pump and the vacuum pump. I looked like it was blow by because they are so close together. Easy fix with a seal kit.
