Isuzu NPR 5.2 diesel 4HK1TC compression test

[@gavinsadler1132]

Did your compression test results turn out to be accurate? Thank you.

[@JasonGut]

Hi, thanks for watching. Yes they were. It ending up being a warped head which caused compression leaks.

have you ever seen a 5.2 pressurize the cooling system with no misfire, no oil water mix, no combustion gas in coolant, and i blocked off egr lines? cold start up goes from 0psi to 5 psi in 1 minute,, any suggestions? maybe injector tube?

First is to pull all the glow plugs son that will crank @ 250 rpm and the testing cylinder will give you correct results

hhhmmmnn ... did you remember the head gasket ..?? ooohhh... a few minutes in, and this is bad.. very very low not even gas motor comp

[@JasonGut]

Yes, there was a head gasket. It turned out to be a combination of a warped head, bad gasket, and leaking valves. Replacing the head and head gasket fixed thed issue.
