I had my mechanic diagnose my 05 6.0L with a dead cylinder, #5 to be specific. After messing with it he said it was probably in the head and I was unwilling to pay the 15 hrs to R&R the single head so I took it home to make a mess by myself. I haven't made it to the head yet but in the process I was tearing into it and the turbo piping has an excessive amount of pooled oil in it. Could this be related to the dead cylinder, I do assume it must be part of the reason the exhaust is burning blue. Any ideas?

 

Moved to the 6.0L Powerstroke Diesel forum.

 

Sounds like a bad injector, what made him jump straight to R&R'ing the head? Oil in the CAC tubes is normal, it comes from the CCV. Search for CCV reroute and you can get rid of the oil.

 

he ran compressed air into the cylinder at rotated the crank through the 4 strokes to hear where it was escaping. He said it sounded like it was leaking back into the intake so he surmised it must in the head. I was surprised it was not as simple as an injector, the pickup only has 61,000 miles.

 

Odd test, I would understand a standard compression test, but applying compressed air and listening kinda baffles me. I would do a compression test to rule out burnt valves, and if that checks out then I would look at the injector.
