dajogejr Posted December 20, 2009 Report Share Posted December 20, 2009 Notwithstanding the questionable tool..where did the idea come from to do a compression test on a cold engine? You always test a cold motor...then a warm motor. If there's not much difference between the two...that actually usually states a motor in decent health. if There's a large number in difference, that signals problems. Lastly, if you pour a cap full of oil through the spark plug hole(s) and crank it over by hand a couple times, then test again...if the compression jumps up considerably that signifies a worn motor as well. To answer your question, a compression tester will not show a leak. It has a check valve in it. Once it has pressure, it will stay on the gauge until you release it via the push button on the valve. To check for a leak, you need a leak down tester. Do a search. You can make your own...or buy one already done. I got one off a guy in MI that works flat out awesome. His name is Bob, and he ports out of his house/garage (like most builders) 517-388-3662 Quote Link to comment Share on other sites More sharing options...
