One of the easiest and best ways to check an engine for serious issues is to use a vacuum gauge. In just 3-5 minutes you can know if an engine is healthy or not. The engine vacuum is just air pressure lower than atmospheric pressure. Test the seal on cylinder heads. The suction device creates a vacuum effect to test the correct coupling between valve and valve seat in the cylinder heads.
