So 17k on a reman long block, initial 1000 miles were broke in with synthetic oil (against manufacture requirements) as soon as I learned I flushed and refilled with DINO oil. That being said, I'm now at 17k and loosing about a quart every 200 miles. I REALLY believe it is my turbo (original to the truck, currently 451k miles. Not blowing smoke but the tailpipe is sooty... no oil "leaks" under the truck.

If the turbo was leaking oil, how would it be indicated?

at $600 to get a reman from Thoroughbred Diesel and I just better replacing the turbo than paying a shop $300 just to find the oil leak?

Is there a better/cheaper place to get a reman turbo?

WHAT is the possibility that 1000 miles on synthetic could have caused issues with the OIL ring on any or all of the pistons during break in?

Thanks guys.

That's good thing. Strange not seeing it wet like ive seen in the past with bad turbos that are either side wet with oil. Get some more miles on that. Go work that Cummins it will thank you.

Sadly I have nothing to "work" it with... it is back to daily driver status... I may hook onto the trailer and go pickup some firewood but even that isn't "working" it like I KNOW the truck likes. :) and the NOT WET status inside and down stream from the turbo is what most perplexed me... I was expecting "wet" as well.
