Pesky vacuum leak

[rob76turbo]

Well I can hear it! A loud pssssst sound on the passenger side of the engine. When I move the hoses, the sound gets louder and then gets less loud. I tried some carb cleaner and a butane torch, but could not detect the location of the leak. And when the motor shuts off, there is an extra loud PSSST. Oh well, my leak detection skills are lacking. Time to take it to my mechanic. They have a smoke machine.

My question is this - the leak sound is very distinct. Should there be any leaking sound out of that side of the motor, is that a common sound? Like I said, my leak detection skills are somewhat lacking. OK, they are non-existant.

Likely best to use a smoke machine to find the leak source.

I find using a rubber hose like a stethoscope pretty good too. Put one end of the hose in your ear and fish around until the sound gets really loud.. Lol, sounds primitive but it keeps money in the pocket.

You make no mention of an irregular idle or CEL, it would be therefore just as well a loss of pressure of the air suspension compressor.

Time is money, save yourself loads of it and let the garage smoke test the intake. Leak will be found in seconds as there are many places it could be coming from.
