For those of you running higher boost (single), do you have positive crankcase ventilation problems?? The reason I'm asking is because while I was dyno tuning, I noticed the oil dipstick would be jumping around under full boost (18 psi in my case) due to the pressure build up.

Does anyone have a solution to this?

vent your oil filler to a catch can and you should be fine.

i noticed the same thing after installing my single...First time I noticed it was on the dyno when I had huge amounts of blow-by...I mean like James Bond smoke screen type blow-by...I installed the catch can and all is good.

I went with the Gotham Racing Catch Can.
