I think the only parts I have left are a couple of lifters, and I didn't keep track of where they came from. What little I saw of the lifter from the bad lobe it didn't (to my untrained eye) look bad.

My mechanic did say that the engine had at a minimum had the head gasket replaced before.

And as to Sid's comments, I agree on both fronts - the DT466 is an awesome engine, but the emission control systems ruined them. Over 50 sensors, two water coolers for the egr, the particulate trap and the regeneration system. They conspire to make the thing very unreliable.

And all that on a diesel that can run and run without so much as an ignition system...
