I had an idea.. maybe someone else already has done this or maybe this test wouldnt even work..

any thoughts would be appreciated..

My idle on my 88 turbo is a little rough. I think its a vac leak.
I have tested vac leaks before, using propane or a vac hose to my ear. These seem to work, yet there is engine noise, safety things I hjave to watch for and a less complete method. Plus many gasket areas are hard to reach, hard to test, when the engine runing,etc.

--Couldnt a guy connect a reducing air hose fitt { made up at like home depot} going to the intake or TID ? then connect an air gauge to it, leaving the engine OFF, so its quiet, and then pressuring the system with an air hose, { how much pressure?}

So say you had 5 lbs air. sealed in the entire intake system, then you could sit back, and watch the gauge.
You could hear the leak if there was one.
You would be testing every gasket, every hose,etc.
It would be easier to find any leak, you could pump up air again, then, retest etc.

If the gauge held air like 10 minutes,etc, wouldnt that eliminate any intake leak so you could turn your attention to air or spark?

What do you think? wouldnt the rotor seals be holding the air? so it would be a sealed system test?

would there be any pitfalls or components that might not go along with the test,etc?

any thoughts would be great to hear..

plug the intake somehow, and put a little pressure into the intake. soapy water will help if you can't pinpoint the leak
