Oil in exhaust

[ctd12valve95]

Over the past few weeks I've been fixing all my leaks, finally got them all stopped. After putting about 200 miles on it I noticed the inside of my tailpipe was damp. I just had the turbo off to replace the pedistal o rings, it was tight no side to side or in and out play. The only smoke i have is on a cold start, seems normal to me. Truck has 160k on it. No fuel in oil or coolant. Only thing I can think of is my injector o rings are going. Just want some opinions before I tear it down, if it is the o rings I'm going to go ahead and replace the injectors

You need to start the truck and let it idle for a few minutes then shut it off and pull the downpipe off the turbo and take a look in it for oil. If it was injector o-rings you would most likely have running and driving issues. You would also likely have oil getting in your fuel filter canister. I would suspect the turbo putting oil in the exhaust more than anything else.

Idles and runs fine, no misses or power loss, if it was the turbo I would have smoke all the time I believe

Not necessarily, I've seen several turbo seals leak oil into the exhaust and no real smoke issues. Since the exhaust runs so cool except when you run it hard for a extended period of time it my not burn it out.

I wiped my exhaust out as far as I could get my hand up in be for I went to work tonight, (30 miles), and it was not damp when I got to work, so maybe it had just happened over time and I've never noticed it, an it's not as bad as I thought
