So, I've got her all torn down now and I'm going back through the pictures and I found these. What caused these weird patterns on the cylinder wall that appear to be something to do with the oil rings, but they aren't all at the same height, and are rotated as well? I just don't get the "ghosting" at all the other levels.
This engine had a oil pressure loss due to the crank bolt being loose, and the #5 rod bearing s*** the bed. The piston was just starting to hit the head, barely. I think I got to it in time. It wasn't my truck until the engine was known gone, so I know no history.
On teardown, I found that the compression ring gaps were nearly lined up on most of the cylinders. What could cause this? Do the rings walk around that much? Was there some disgruntled employee at the Mr T factory that day? I'm 99% certain that this engine has never been torn down, at least to the level I have it now.
Back to the frosted pattern on the walls, do you think water sat in the cylinders for a while and ever so slightly corroded the pattern into the walls?
I don't know. It won't be a problem in a week or so, but I thought it was interesting at least.
Thanks,
Jim
