Post Mortem on a 360
So I finally got the 360 out and on a stand to finish teardown. Beyond the obvious corrosion from water intrusion, the excess coolant in the oilpan was the result of a crack in the wall of cylinder 1, my guess is it was created by too much nitrous. All main and rod bearings were trashed, with number 3 connecting rod bearing being reduced to the size of a nickel, and the corresponding wasting of the crankshaft throw. I also found that the oil pump pick up tube was loose enough that it appeared to have rotated slightly, potentially leading to oil starvation and maybe the catalyst that lead to the eventual death of the motor. Inside the timing cover is spotless, as are the bottom sides of the pistons, so I don't think this motor had a very long life. Also had a Comp 274h cam. All scrap metal now.
