Black Owl Posted August 1, 2008 Share #2 Posted August 1, 2008 What is a good way to check engine cyl compression? I realize it sounds dumb but there has to be more than one way Well, I uzta do it by sticking my finger in the spark plug hole. If it blew my finger out, there was compression...

oldandcrotchety Posted August 2, 2008 Share #3 Posted August 2, 2008 Onliest way I know is to use a compression tester. They don't cost much. They're just a pressure gauge on one end of a hose and a threaded end that screws down into the head instead of the spark plug on the other end. Mine has different thread patterns for different applications and it will hold it's reading until you let off the pressure with a little valve button. I'm pretty sure mine was less than $30.00 and it works real well. Should have one a NAPA or other parts house. Link to comment Share on other sites More sharing options...
