finally did boost leak test

[baxsom]

ok i finally got around to creating one of the boost leak test thingys
i get air coming out of the valve cover filter and out of the check valve on the cartech fpr
when i plug these i get a hissing from somewhere that i just cant find anywhere
i have checked every vacuum line, every IC piping connection, the tb gasket, the BOV.
the line to the boost controller and i just cant find it

any suggestions on a hidden area that i didnt think of looking
the sound is coming from the back of the motor

If you plug the valve cover breather and still hear hissing check your dipstick. If its coming from there than your PCV valve isn't closing correctly under pressure.
