Has anyone on here performed a boost leak test before? I did one the other day on my 3rd gen 3sgte and I think I f'd up. I hooked my tester to the intake side of the turbo with the oil cap off I wasn't able to build any pressure in the system so I stuck oil cap on and it worked...but around 7psi I noticed air leaking from around the valve cover gasket. I read everywhere that you aren't suppose to leave the cap on during the test so I'm kind of worried. Please advise!
