Sounds like a misfire please help!

That is probably unburned diesel mixed with carbon because that injector may not be spraying correctly. That could be your miss!

God I hope so!

You know, now that I’m thinking about it…..I did 2 compression trsts, the first one was a fail b/c I didn’t disconnect the pink wire and the truck was spraying fuel and almost firing, which clogged up my gauge check valve so I had to fix and do a second one…..
Anyway point is it was spraying fuel on first test. So that back left injector is just pissing out, not atomizing the fuel. That’s the puddle I got on floor. So HOPEFULLY that injector is bad and that’s my miss. I will know once all my parts come in at the end of the week. Stay tuned…

Combustion chambers wet with diesel will give abnormally high pressures on compression testing. Some diesel will burn due to pre chamber turbulence.

Diesels typically have little manifold vacuum but worn valve guides can get oil seeping into the valves overnight.

UPDATE! After another reman injection pump, reman injectors, new glows, and an exhaust leak repair, she’s running great! Adjusted my vaccu for shift points which keeps it in lower gear longer so not falling on its face all the time. For a 6.2 she’s pretty peppy now! Thank you for all the help everyone

See that? It was that damn exhaust leak all this time!

Well it was that coupled with a few other things, just sucked they both happened at once, but my IP did have a lot of air in the return, so that was on its way out, and the injectors looked like trash
