Restoring an Old A-65-8F

[Dan1940Chief]

I need to replace my Lycoming O-145 and found an old A-65-8F on ebay.

It looks like it sat for a long time and has no logs.

Question: can this engine be overhauled and restored to service?

Dan,
Don't see why not but you won't know until you take it apart, I guess. New parts are hard to come by but there are lots of 'serviceable' parts around. Cylinders are getting scarce so you'll most likely wind up with chrome but they seems to work pretty well on A65's although I prefer steel if I can find them. Be sure you have the cam bores checked for being oversize. They tend to wear after all the years and hours and a prime spot to lose oil pressure.

I have some A65 parts that I've collected over the years thinking I might need them at some point.

Thanks, Mike -- great insights...

Dan,
If it has logs and a data plate, go for it. If the logs are missing you'll need to bring all of the items up to serviceable standards and make new logs. This would be an overhauled engine.
If you have the logs all of the parts can be inspected, if they are beyond service limits but under the max limits you can put it back together and this would be a serviceable engine.
If it is missing the data plate I would steer clear or it would have to be real cheap.
