ABSTRACT:
An apparatus for in situ testing of an internal combustion engine for vacuum leaks is provided. In accordance with the present invention, smoke is generated from a suitable smoke-generating fluid in chamber means, and then sealably communicated through conduit means to the intake manifold of a vacuum system in an internal combustion engine. By visibly observing smoke exiting from any of the hoses, flanges and gaskets contained within a vacuum system, leaks therein may be readily located.
