has anyone had problems after tuning with internal crankcase pressure, i did on my 07.5 and just bought an 09 and modded the pcv system to the ground,just wondering if anyone else has this problem or am i alone thanks Loren:

I Did! I used too small of tubing causing high crank case pressure, which in turn started to force oil by my seal's in the turbo.

I changed out all my vent lines for the PCV re-route to 3/4" I/D at the T-Fitting going to the valve covers, and then 1" I/D going from T-Fitting to bottom side of truck.

Problem is now gone!
