My Ney Enterprises Re-Man Lasted 200 hours

Caution to those pondering a zero-choke re-man by this company.

My O-470J lasted 200 hours before four cylinders showed mid-fifties
compression with Blackstone labs reporting symptoms of excessive ring
wear.

Even after admitting, view phone, that the test-stand results were
abnormal, Ney himself refused to stand behind the engine, on the
grounds that the plane's former owner -- his customer -- made him use
reconditioned cylinders.

So I guess he's saying that he can't build an engine unless he has new
TCM or Millennium cylinders. Sure was able to sign the logs and take
the money, wasn't he? And what's wrong with reconditioned cylinders?
Ever notice the crap that comes out of the continental factory?

That's one of the problems with buying a plane with a recent overhaul.
There isn't much of a chance that the seller did a good job of
overhauling the engine if he's just hours away from selling it. You'd
probably be better off buying a run-out airplane and getting the
overhaul done yourself. Also, you'd know that the engine was properly
broken in.

For purposes of avoiding one when buying, what's a "recent overhaul"?
100 hours? 200? 300? Put another way, after how many hours on an engine
can you tell that it's properly overhauld and broken in?

It's not really hours so much as calendar time, IMO. If the engine was overhauled
within about the last six months and there are no extenuating circumstances (such as
lost medical or death of the owner) prior to that, I would be a little leery of the
quality of the work. On the other hand, a "name" shop like Mattituck doesn't cut
corners on request for anyone (though their engines *have* failed on occasion), so I
would tend to assume the work was good if it came from one of those shops. There are
other factors besides time.

AFAIK, there's no way to really be sure that the engine was properly broken in,
especially with chrome cylinders.
