Manufacturer TBO is 2000 hours OR 12 years - its a runout engine, and
the price should reflect it. The cam is the most vulnerable as far as
disuse, yes - all splash lubrication up there. Pull a jug or two and
look, beyond that, if it isn't making metal, burns reasonable amount of
oil, and has decent compressions, I wouldn't sweat it much, either.

Hey Guys,

I'm looking at at 172 that has 1100 hours since overhaul, holding 73/90
++ on all cylinders...the only thing holding me back, last overhaul was
1976...

I've talked to several seasoned pilots / aircraft owners that say as
long as it's holding good compressions, don't sweat it....

Any opinions?

Thanks,
