Compression Test Procedure

Compression Test Procedure
So I'm talking to someone about a car and he says "I had all the plugs disconnected and was cranking with the compression tester going from each leading and each trailing home" which doesn't sound right to me. If he had all plugs out, it would read abnormally high, right? Pretty sure this is a no go car. It's got some issues with stalling as well. I think I'm just looking to have someone smack some sense into me. Lol.

Thanks, I thought that's how it was supposed to be run. His numbers he gave me were in PSI and he didn't know what RPM. 105, 98, 92, 101, 100, 98. Looking at the chart in the Newbie area, those are kind of borderline.

You need to make sure the engine was at normal operating temperature when the compression test was performed. Doing a compression test on a cold engine will give you higher numbers that will not correlate to the numbers st normal operating temperature.
