I tryed pressure testing the hoses on my S3 today.
I made a 80mm plug, put a shrader valve in it, and put it on the inlet hose, where it connects to the MAF.
I then removed one of the hoses connecting to the inlet hose (the larger of the two) and plugged it off. From what i can see, this hose i removed is the breather hose for the engine, as it connects back to the top of the head ?? The smaller of the two i left attached ( goes too vent side of N75 valve).
When i apply pressure i can hear what sounds like oil bubbling in the sump, as if air is leaking back into the engine. Tho i can see no other route it could get there other than the hose i plugged off.
Any ideas ??
Any help would be much appreciated!!
I cant seem to find a good write up on how to do a pressure test, and i have no manual to refer too.
Cheers
