blowing oil out the stack....

hey J....nice to see you...sorry bout your truck probs....

 

Possible it's turbo, have to pull it and manifold. If only one hole oily in head it's a cylinder problem. If all holes are wet it's a turbo problem. Could have dropped a valve and busted a piston but that knock is unquestionable.

 

I'm thinking it is a turbo problem, you can tell by pulling the exhaust pipe off the turbo to see. If it is, then your cold side of the turbo is really something you need to worry about because if those seals go, then you have a run-a-way engine and kiss your overhaul goodbye.

 

I'm betting the seal failed on the exhaust side of the turbo! Hope Im right, I think thats about as cheap as it can get. Good luck to you.

 

I'd give it some time. A Detroit Williams master tech once told me it can actually take up to 60k miles for rings to properly set in the cyls.

You mentioned you just had an overhaul done. Give it some time.

 

So I got a real bazaar one for ya. Buddy has a 12.7 DD. It did exactly the same thing. New turbo, next day same thing. Turns out, the internal pressure was so high the easiest way to get out was the ex turbo seal. The cause was, when it was rebuilt they never cleaned the breather at the top of the valve cover. Was completely plugged. He cleaned it out so the crank case pressure could exit, and no more problem. You never know?

 

I guess you missed the part about it being 5 gallons low on oil.

 

Very good chance it's a turbo. I'd say put one on anyway if you didn't when it was rebuilt. I see you had to have it rebuilt hope it all works out for you bud!
