So I  inspect each individual hose from the igloo to the IC to the turbo to
the  throttle body and can't find a tear.  I built a pressure tester with  a
schraeder valve that I hook up to the Igloo to IC hose.  I  disconnect and
plug the hose to the ECU and the two hoses (one by fender  and the other
towards the IM off the igloo.  So why can't I hear any  leak(s) and can't
pressurize the system (using a portable tank that I've  already filled to 20
psi?

Suggestions?  I'm  stumped!

An adequate CFM flow must accompany the pressure, as there will always be a  
valve open that will let pressure through the engine. I have found sometimes  
when I have tested that it will pressurize easier than others, and I am 
clueless  as to which rotational position will yield the best pressurization. Anyone 
else  know which piston up gives best pressure test?
