Finding A Vacuum Leak With Propane

[@GhostMerc86]

Excellent! Finally a video that shows a running engine with a vacuum leak and the change the propane makes.

Fantastic video from a great teacher. About to check for leaks on my 1991 Bronco and now looking forward to it!

i usually shove the hose in my nose to see how much propane is coming out

Thanks for sharing! I'm gonna try a home made smoke machine tomorrow. I suspect I need intake gaskets because I've seen some coolant on top of the block on my Ford Windstar 3.8L. Not to mention an occasional spudder in the engine.

Can I just use map gas?

Hello, can you use Bernzomatic insted of Propane ? Can Benrzomatic damage the engine / sparkplugs / injectors due to high temp?

I sprayed propane straight into the intake and it didn't react.

Same here but was testing a 2 stroke. Needs more propane?
