[QUOTE="wjurls, post: 6329684, member: 50731"] Even a healthy cylinder won't hold completely. A low compression cylinder will show a leakage of greater than 20%. How it works (the short version) is you thread the tester into the spark plug hole and set the cylinder to TDC of the compression stroke. Then you connect a compressed air source to the leakdown tester and that will show a leakage percentage on the the gauge. More than 20% on a cold engine is cause for alarm. Even less is a concern on a warm engine. While the cylinder is charged with air you can then listen for the leakage through the intake, the exhaust pipe, or the crancase to determine where it is originating from. Mine was bad valves and I actually heard the leakage into adjacent cylinders and not through the tailpipe or intake oddly enough. [/QUOTE]
