Old Engine = Runout Engine ?

[hewilson]

I have a similar question on this topic for you guys.

I am taking a look at a 336 with low TTAF, only 1670 hrs. The engines are original with a "top overhaul" 330 hrs ago. I have not yet seen the logs for myself but the seller claims it has always been flown on a light but fairly regular schedule. He claims the compressions are good and there is no metal in the oil.

My question is, should I consider these as run out engines? Given the TOH, the compressions and the lack of oil, how much additional time could one expect to safely use those engines?

Given that the engines are origianl, I would need to replace both cranks at O/H or reman so I imagine doing both engines would be in the $60K range. Is that a reasonable rough estimate?

Thanks in advance for any input.

I am planning to be in OKC but probably not with my own Skymaster yet at that point. I'll probably come in commercial. But it will be a great chance to see some Skymasters up close.
