that is some mighty expensive guessing there thats sole purpose is to make them money. How about instead ...

Pressure test the turbo oil circuit for leakage by capping the oil lines and pressurizing them to about 60 psi. I know Mr. Hag has done this a few times and it seems to be an effective method for determining turbo leakage in the exhaust and/or intake side.

Also,.. the Cm2250's and 2350's are known for valve guide seals to leak oil into the exhaust. nothing like mis-diagnosing oil leak issues into the exhaust system by throwing the most expensive parts they can think of at the truck without any kind of actual justification eh?

I would have told cummins to shove that blind guess-work at the expense of some truck owners hard earned money right up their poop-shoot sideways and come up with a better testing method that involves actual troubleshooting and diagnosis!.
