The smoking seemed to go away. We did one more track day-the second one- and there was little smoking. At the end of the session, the #4 rod spun a bearing. I took the engine apart to repair the crank and rod(s). The #4 piston was the one that had been replaced-it was visibly different from the others(different dome as well as lots of grinding on the back side of the piston). The piston oil squirter on the #4 was completely clogged-I would guess that is the reason the piston failed in the first place.

I replaced the crank and used another set of rebuilt rods. Since there had been a top end refresh, I assumed that the heads were OK. As I was getting ready to reinstall the heads, I decided to check the heads. The valve guides were worn very badly as were the valves. I do not know specifically what was involved in the top end refresh-but it did not involve replacing guides or grinding the valves (since you cannot do that correctly if the valve guides are worn badly). I had the heads rebuilt and and the valves replaced and the seats ground. I now have the engine back together.
I have to assume from this that the top end refresh consisted of stopping leaks-the engine was dry on the outside. What I got from Don was an engine with a clogged oil squirter, 5pistons of one CR and 1 with another CR, and completly worn out heads. The spun rod bearing was probably a function of the engine just being worn out.
I have attemped to be as factual as possible in this description without interjecting emotions into the description. Given the description of the engine and the work performed on it prior to my purchase-I felt I got ripped off big time.
