[halerazor]

were going to do it on my buddy's 04 so i've read that you can stick the airline either in the icp port or in one of the oil rails. what kind of air pressure do we need and i also read somewhere about changing the duty cycle. does the duty cycle need changed to do the pressure test

You need a scan tool with active command capability. Put the IPR duty cycle to 85%. You shouldn't put it there for more than 30 seconds. Feed air to the port and listen in the valve covers for leaks.
