We changed the engine in WC's ride yesterday (Sunday). He bought a runner from GR here and then put new rings with a hone job and head gaskets on it. We had it out on the floor with the trans in 2 hours, and then it went slooooooowwwwww. 7 hours to swap all the external engine parts over (embarrassed about that). Then more hours to rethread the trans back on because the new pilot bushing had a little tighter ID than it probably should have. It still drags a bit in gear now. Hopefully that will loosen. WC had the injection pump timing out by 180 degrees, so we had to re-pull the radiator to access the pump gear and rotate the pump shaft 360 degrees with its 3 adjustment bolts out of the gear. After that, then the red toothed gear became visible in the shutdown window and she took right off. Lesson here was just because both rocker arms are closed at TDC on the damper doesn't mean it is up on the compression stroke. You could still be 180 out. You have to rotate the engine in its normal direction, and watch for #1 intake valve to be closing, then next damper TDC mark is TDC for the power stroke. This was all WC's doing, not mine. Wish he would have read the manual! Anyway, it is done, he drove it home, and was a 17 hour continuous work day minus 30 minutes for dinner. He drove home @ 5am Monday morning, and I am pounding this out at work right now on 3 hours of sleep. There is no smoke out the exhaust pipe, and he said there is a little vapor out the draft tube so far. We'll see what that does once he puts some miles on it. The rear main seal he just redid as new on his previous engine was leaking like crazy, and the existing one on the engine he purchased looked relatively dry, so I advised not to touch it. Actually the entire engine looked good, I would have ran it as is, but he was hard up for new rings and head gaskets. Stay tuned, he'll probably post an update and maybe a pic or so.
