well i tryed to do a boost leak check as described in one of the recent posts i came across. I fitted a 2" pvc cap with a tire valve into the turbo outletand tryed to presurize it to about 20psi to see if it would hold. Supposedly it should for 10-20 minutes no problem right!! wrong... my car wouldnt hold the pressure for more then a minute. I assume my stock piping is crap and must be leaking. ANyone else have this problem and what do i need to do to fix it? Should I order hardpiping or just buy the stock and reinstall it all? I recently dynoed with the mods listed in my sig and came up with a 376 rwhp and 395 ft/lb torque which seems low for BPU supra. Also there is a little little coating of oil inside the piping and coming out of my BOV...is this normal? Its only a very small amount.
