This needed mentioning at the beginning of the thread. There's no way any diagnosis can be done by anyone over a forum without all the information.warriorBX wrote:i have had a considerable loss of power.
Did you read what I wrote above? These turbos do not have bearings. The shaft floats in a film of oil.warriorBX wrote: I wouldn't be suprised if the bearings were damaged too,
As mentioned by Doc, the turbo on an XUD will almost never fail. In 99% of cases they outlast the engine. I'm also wondering just what you expect to be done to service a turbocharger?... short of changing the engine oil there's nothing else that can be done. Anything more than that would mean needing an exchange reconditioned turbo.warriorBX wrote: the old girl's done 181986 miles, and i doubt the turbo's ever been replaced, let alone serviced
