Say Wil, -I assume this motor is going to be totoally disassembled?
If so, I am really curious about the oil control rings. I had an engine one time that I unknowingly had "stuck" the oil rings, due to excessively high combustion chamber temperatures, which caused the upper half of the pistons (just down past the oil rings) to run too hot. -What happened was I was messing around with air/fuel ratios, and had run the car in an over-lean condition at highway speeds for probably a day. From that moment on, the sucker used oil at the rate of one quart every 200 miles.
Now here is the interesting part of that story: That engine performed perfectly, compression tested perfect, no leaks, no smoke, no smell. It was burning the oil so cleanly that it was not visible. And I think part of the reason for no smoke, was this: the only time that the "oil control" was totally lost, was with the engine running at highway speeds. Under town-driving conditions, lower speeds, lower temps, etc, the cylinder walls were not being "oil flooded." -but were under highway conditions.
-and by the way, the rest of that engine was in perfect condition. -no damage, wear, etc. -just oil rings stuck in their grooves, which made it impossible for them to scrape the oil off the cylinders.
I am WAY CURIOUS to know what you find on this one
