Thread: boost leak test help

well i try to pressure my system to check for boost leaks and i can get only to 10psi before the dip stick flys out. am i doing something wrong? im testing it thru the intake pipe on the turbo

That is a little weird, I take mine up to 20 or so and that has never happened to me. You could just grab some vice grips or something and clap the PCV hose and the hose from the intake to the catch can with another, and pressurize

That means you are pressurizing the crankcase.
You either have a bad PCV valve or have the other valve cover vents set up wrong.

Some how your getting air into the crankcase, careful you dont start pushing out seals

all my vents should be good never touched them.. one of the hoses goes to the intake pipe which should be correct? ill check the pcv valve
