Repeated Turbo Failures

[Tmaj12k]

I bought a new turbo and actuator from a place named Turbo Solutions in South Jersey. (Pennsauken to be exact) back in July. They put a 1year warranty on it and already I have gone back 2 times. The turbo started pushing oil at the end of August due to a worn seal. A vague answer was given as to why it happened. Something along the lines of internal parts can have unexplained failures even when they’re new. There also could have been debris in my oil. They replaced both the turbo and actuator for me. The actuator also had an internal failure. On the 9th of this month the turbo started pushing oil again. I took it back, they rebuilt the turbo and gave it back. Apon taking it apart they saw that the seal had worn out again. This time they said it could’ve happened due to excessive back pressure or maybe crank case pressure. I have a Cummins ISX with 758k Miles. When I first bought the turbo back in July I also had my dpf filter baked. I do my pm’s every 10k miles. I’m keeping up with my maintenance. The engine is probably due for an overhaul soon but are they telling me the truth about back pressure or crank case pressure making the seals wear out? To me, that’s general language used to put the fault of the failures on me and the Truck and not their turbo.

Oh. Wanna hear a kicker to the story? I just got the rebuilt turbo installed last Thursday 1/18. I worked for a week. On 1/25 I see a little oil leaking from the turbo again.
