Need to find a vacuum leak

stangGT95 · 11-10-2003, 02:48 PM

I have a vacuum leak and have narrowed down its location but can't find it. Is there any way of finding it...say with spray, smoke or something else? Thanks for any help.

I like to use brake clean if I have some laying around, which I usually don't. So I use whatever on hand, even water.

I use a little propane hand held torch. Just turn on the torch and spray a little propane on the suspected area if the car revs up its cause it is sucking in the propane through a vacuum leak.

Starting fluid and break cleaner both work also.
