Yes, a manifold vacuum check is one good way to determine the health of an engine. A high steady reading after the engine has warmed up is a sign of a healthy engine.

It won't tell you if the owner was negligent on changing the oil and the inside of the crankcase looks like Carlsbad caverns though.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
