Actually, propane is the 'official' approved (EPA, & B.A.R.)gas to use for finding vacuum leaks. At the shop, we have a special adaptor (get from one of the tool trucks)on a bottle of 'camping' propane, with a hose to spray the gas(in short, small bursts) along intake manifold gaskets, and fittings, etc.

A leak will show up quickly.

I don't recommend this for home use or beginners.
