Default Lyc. O-360 cylinder question

I recently bought an O-360-A1D from a parted out Geronimo Apache to
use in my RV-8 project and have a question (or two) regarding its
background.

The engine was installed on the Apache in late '95 and has a new
Lycoming logbook, no previous logs included. Makes me think it's a
Lyc. factory reman engine, zero timed and all that... but, on the
first page of the new log it shows the TT on the core at 2022 hrs.
The work was done by Lycoming at Williamsport, PA; would this be
considered a factory reman or factory overhaul? I can't quite tell...
don't guess it really matters though.

My big question is this; whether reman or O/H'd, would the cylinders
installed by Lycoming be new or overhauled ones from the jug bin? I'm
planning on a field overhaul on it, and assuming jugs were new in '95
(1660 hrs now) I'm tempted to have them overhauled and re-used. If
they were used, O/H'd jugs to start, with no idea of TT or history,
I'd trash 'em.

I'm pretty sure that Lyc installs new jugs on O/H's or remans, but
what say ye, engine gurus?

I'd suspect the engine is a reman and they installed new cylinders at the
factory. Teledyne keeps records on its reman engines and I bet Lycoming
does too.

Even if the jugs were new in '95, check the difference in price between new and
overhauled before you decide. You might find the cost difference isn't enough to
justify the overhaul, just go with new.

Jack is right. It's a factory Overhauled engine. It's just as good as a
reman, if you ask me.

Overhauling cylinders is a crap shoot, even more than new ones. Think
about this, if even ONE goes bad, your economics are shot. The delta
between new and overhauled cylinders is not big enough.

I overhauled first run cylinders on my Cherokee 140. 750 hours later, I
have already pulled TWO and ANOTHER ONE is now going bad. This engine
was overhauled to new limits at a "big" shop (G&N). And, 0-320 engines
are not known for their high failure rate.

Never again.
Good Luck,
Mike

A Lycoming factory reman will have a -R (dash R) suffix on the serial
number. The logbook entry of 2K to start seems to indicate it was a
factory O/H, not a reman. A reman gets a zero-time logbook to start.



Well there's my answer... no -R on the serial, it's a factory o/h
then. I'm still thinking about what to do with the jugs; I know the
prices of new ones have come down quite a bit, with jugs from ECI and
Superior going for around $900-1100 or so, but still... if these are
first run cylinders with 1660 hrs, and the engine was running great
when removed; there's probably lotsa life left in 'em after an
overhaul, and I'd get to save several hundred bucks per jug. It's not
that I'm a cheapskate, but I'm not rich either... it's nice to save a
few bucks.

Thanks for the responses!
John

I don't know what your prices are but here an overhauled chromed
O-470/520/550 cylinder is $350 vs a new cost of approx $1100.
