maint. man,
The head I don't think is hurt. We had to remove the rocker arms and push rods just to get at all the head bolts. The valve stems "looked" alright. We were planning on reusing the head ourselves but time will tell.
1tuffram,
We thought about the turbo and also the vacuum pump. Both have oil lines going to them but if they don't replace those right now, at least they are not that difficult to replace latter if need be.
A couple of other things we found when we tore in down was that the piston oiler for the #1 piston was broken off. We looked for it in the pan, on the shop floor, everywhere and never found it. We are wondering if it got broken off at the factory when the engine was being put together. Its just a little piece of hard plastic sticking out of the main bearing journal. Don't know if that would have started this whole mess or not. Also the oil return tube from the turbo has a short piece of rubber hose connecting it to the block that had been replaced sometime. The hose and clamps weren't like the rest on the engine.
Now, more about the phone calls:
My cousin who lives in Illinois had called my parents over the weekend for a family member's address. Dad got to telling him about the truck and my cousin said that he knew someone who works for Chrysler and used to be pretty high up in the warranty department and he would give him a call on Monday. (Dad said he never mentioned anything to my cousin or anyone else about the TDR. )
Tuesday Morning, the Zone Rep calls dad to tell him that they are going to fix the truck. He also tells him that he had talked to Cummins and that they were going to pay for it since it was their filter.

I don't know I believe that one.
Tuesday afternoon, dad gets the call from the guy from California. (the area code on the caller ID is from California, no name though). This is the guy that said he had read what was on the TDR website. Dad said the guy from Calif. also said to have the dealer check the oil pressure regulator valve spring. He said some engines had springs in them that wouldn't allow the valve to open like it was supposed to. I did take the valve to Cummins and the valve wasn't stuck, but I didn't think about the spring. It sounds like there may have been some other engines that this has happened to.
We are trying to figure out if all these calls are related or if it was just a coincidence. We can't figure out how they could be connected.
