Here is a follow-up to my original post. I went back to visit the engine
and pour over the log books. The engine is an O-320-E2D. It has 2750 hours
total time. It has had one major overhaul. All AD's have been complied
with and the crankshaft has been machined .003" with no pitting found
inside. The records were meticulous as the engine came out of a Part 141
flight school. The engine was never stored. In fact the owner swapped a
fresh rebuild right after flying the plane from Florida. In 9.5 hours oil
consumption was 1 qt and the gauges were in the green all the way up from
Fla. The starter is less than a year old and the carb is less than 1000
hours old. Compressions at the last 100 hour were mid 70's. Never had any
oil contamination. The only thing bad I can find about the engine is it is
past TBO. Anything else I should consider before plunking down the cash?
