Ms Piggy. Black and Blue!

You might be able to tell from the one pic above, but if not, the alum timing housing was cracked right where the infamous 'killer dowel pin' resides. I am going to have it welded up. Between that and the loose valve cover on cylinder #1, those were the culprits to the layers of extinct dinosaur ramains coating the outside of the engine.

I threw in a pic of the push rods stuck through some cardboard. That is a handy trick I learned years back to keep them organized. Works great and the price is right!

Here are some more pics of the teardown. Everything else looked good. The rod bearings had some wear on the upper bearing. Talked to a buddy I ride bikes with who works for Cummins and he said that is normal and that some guys cheat and just rotate the bearings 180 degrees and reuse them. No thanks.

Getting the pistons/rods out was made easier by my high dollar 2x4. Fit perfectly in there. Removing the crank turned out to be about the hardest part. That friggin thing weighs as much as I do!

Overall, the engine was super easy to take apart. Almost reminded me of a Briggs motor, with the flat tappets down in the block like that. At least this engine uses an oil pump instead of a slinger for lubrication.. My thought as I finished the tear down was that this engine doesn't really appear to have been designed for performance, just function. Nothing is super fancy or involved. Just big and heavy, kind of like the rest of the truck.
