Engine/Transmission (1998.5 - 2002) compression test

[Wyomingcowboy]

Is there a way to test compression in our GlowPlug-less Cummins?

Yep you have to remove the injectors and get a compression testor that fits where the injector goes. best thing for you to do in your situation is to pull the head, your gonna find out what exactly went wrong easier than trying to do the compression test, by the way it takes about the same time to pull the head as it does to do the compression test.

Snap-On makes a really nice compression tester set. It costs a couple hundred dollars. But I found it to be worth it.
