[s-cars] Stumbling saga......quick pressure test question.....

[djdawson2 at aol.com]

 Weird... I've done this testing dozens of times and never had that problem.  I routinely test at 10 psi... and I never block the crankcase.  My compressor has a 60 gallon tank, however.

Even if you block off the crankcase breather, you will not be able to
obtain 15psi because the MAF to turbo hose will start to expand.
I'm guessing it will eventually burst as it is not meant to hold
pressure.
I recently attempted to pressure test my 20V urq this way and the MAF to
turbo hose expanded to about 6" before I cut the air.

> Yeah... disconnect the MAF to turbo hose at the MAF.  Put your pressure tester 
in the end of the hose and clamp it tight.  You will need a regulated supply of 
air that is large (compressor tank with regulator), because the system holds a 
large volume and air pressure will be constantly lost through the crankcase.  
Regulate the air pressure down to 10-15psi and hook your airline to your tester.
