bleeds off . You need to fill your compressor tank up then cut it off and all other noise in the area . Regulate the air entering the system to 5psi , turn it on and leave it on . Leave the regulated air on and listen for leaks , youll hear air moving through the system the whole time but youre listening for more of a hissing sound . Move around the intake system , under the front of the car and anywhwere the piping runs and listen for leaks . Until youre comfortable with this proceedure and how well you can regulate your air to 5 psi id leave the dipstick out and the oil cap off to releive any built up pressure but this will create more noise from the air exiting and make leaks a little harder to detect . Ill see if I can find my writeup . good luck
