Boost leak Test Question....(Air inside Crankcase)....
So I followed the youtube video showing a boostleak test on an A4 B5 1.8t.
http://www.youtube.com/watch?v=s29Q77hK-i4
So Got my homemade pvc end cap with glued in air valve stem ..I clamped it on the Intake hose just passed the MAF, removed the pressure regulator valve and replace hole with rubber cork, and leave the Oil filler cap off.just like the video.
When I started pumping air thru to check any leak...I didn't detect any...
All I can hear is a distinct "Glugging" sound inside the crankcase meaning air
bubbling thru the oil inside...Is that normal???
