Is this the original engine?
Hi, is there any way to tell if the engine in my truck is original? The guy I bought it from says it was a "Navistar" replacement installed at 200,000 miles. Since everything this guy has said since then has lacked a certain amount credibility, I am now wondering if it ever was changed. Not that it really matters, but I would like to know what the real miles are on the engine.
Thanks

At this point, I'd check the condition the engine is in -- get yourself a diesel compression tester and test the cyl compression. That will tell you a lot about how much life you have left.
Also, I'd probably assume that the IP and injectors should be replaced at this point, unless you *know* they've been replaced within the last 50K or so -- beyond 100K or so, the pump and injectors start to get sloppy, providing reduced power, reduced fuel economy and poor timing control.

I have a good idea of the condition of the engine. 500 psig on all the cylinders, new glow plugs, R&D-IDI Pump and injectors. I am just curious if the guy was loading some bull with the "new engine at 200,000 miles".

It might have needed a new engine at 200k if not maintained right or for some other reason. To find out if its the original, I think would be very hard unless you could find paperwork that listed the serial number of the org. engine. Though I don't think that it was put on any paperwork from new. But I could be wrong.

The question is: What does it matter? with the engine in such good condition, either the truck has <100K or the truck has <2-300K and the engine <100K, and I'm guessing the latter. I'd assume that he's probably telling the truth, considering that it doesn't matter either way at this point.
