I bought a 172 and it had only 4 hours in the last 3 years when I bought
it. I got a very good deal and the only problem was one bad exhaust
valve. That was found in the prebuy and the owner had it fixed. I flew
that engine for 400 hours when I finally installed a factory OH engine.
The engine ended it life at 2000 hours due to the uncertainity of the
oil pump AD and what I was going to have to spend just to find out.

I'm looking at at 172 that has 1100 hours since overhaul, holding 73/90

1976...


1100 hours in 29 years? That's 38 hours a year. The insides of that
engine are full of rust and everything is going to go to hell all at once.
