Re: Questions about crankcase venting

Ok, I've gathered some more info. I tried a custom drain tube and now it does not smoke on cold starts anymore, only WOT shifts. Well, after putting a low pressure gauge in the dip stick tube I found out why. Damn thing made 3psi of pressure... in the crankcase, under full boost. pretty sure the limit for holset/garrett turbos is a fraction of 1psi... I made a custom catch can out of PVC, ran 3/8" line from both valve cover breathers and a 1/2" line to the intake. I'm for sure pushing coolant now too, so now I'm thinking not only pushing coolant but pushing air to the crank case? Did a sniff test on the coolant doesn't have Hydro carbons at idle.
