I need a favour from anybody with a 1996 T5 20V Turbo. Next time anybody is checking for vacuum leaks or even if somebody can check this for me I would be v grateful.

Recently when checking for a leak to cure v lumpy running, I rigged up a DIY smoker using an air compressor as the blower. This wasn't v effective as I could not get fuel to smoke v much or for long. But I did get a sound like escaping air near the fuel rail or under the inlet manifold. I have replaced all of the injector seals, but the noise persists. I know there is a hose that goes along under the manifold to the PCV, but before I take the manifold off, I want to know if anybody else gets the same sound when they blow air thru the system, in case it is the noise of air escaping thru the open inlet or exhaust valves.
Hears hoping.
