I told the foreman that the engine was shot and doing a top end would just make an oil burning, smoker even worse. He said to just get on with it which I did, buttoned it up early in the morning hours took it for a test drive. It left a thick cloud of oil smoke for several miles. I took it back and wrote up a report sheet that basically said rebuilding the top end only made its smoking habit worse. Next day it was gone. Day after that it was back in my stall with instructions to pull it apart and rebuild the bottom end. Did that with an overbore, new pistons and rings, new bearings, etc. Put the heads back on fired it up no smoke no oil consumption beyond what you'd expect for breaking in the rings.

i wouldn't really consider that proof would you?
to me it sounded like the lower end was already bad. i think the op was referring to the top end rebuild causing the lower end to have problems.
or maybe i just misunderstood your post.
