bad cylinder

New.

Yup. I just got off the phone with pricing from Superior & Air Power.
Not only that, but a local EAA member wants the old core.

2) If buying a new one, which company? And is there a core refund?

Millennium, hand's down.

Yup. That's the pricing.

3) What is the difference in break-in procedure for overhaul v new?

No difference.

Make a cool lamp out of the old cylinder!

Tried to make a lamp out of the old fixed gear, no luck.

On my way to the airport to talk options with the shop. It may not
be the entire cylinder. It may just be the rings, and the cylinder is
still good.

If that cylinder went 2500 hours, gave you no trouble, then why not buy that
brand. You know what kind of service you got out of this one, seems to me
there is no reason to look elsewhere. Just my .02 worth.

Looks like cylinder #1 on an O-360 is dying. Shop says I could get
more time out of it -- good compressions, no metal, but the bottom
plug is covered in oil. Since it has 2500 hours on it, I figured that
it's time.

So -- the big questions

1) Overhaul or buy a new one?
2) If buying a new one, which company? And is there a core refund?
(No, I will NOT get the "Lycoming" brand)
3) What is the difference in break-in procedure for overhaul v new?

thanks

What was made 2500 hours ago is probably not what is being made now. One
only needs to review all the recent engine ADs. Cylinders have been
especially troublesome for both Lycoming and Continental. I would not buy a
cylinder from either.

And ECI currently forced to replace thousands of cylinders doesn't mean
a thing, eh... Interesting...

Lycoming had an AD on cylinders in 1976 and that AD has since been
canceled...In fact, the only current AD's regarding cylinders for
Lycomings that I can find on a quick search are against ECI and
Superior...
I don't have an axe to grind here... I'm interested in facts...

Not sure who you are talking to as you have not seen fit to include anything
other than your response. Lycoming has had numerous ADs on crank shafts
(the numbers are still growing). Continental cylinders have been junk for
decades. There was (and still is) an AD on some Continental cylinders that
requires retarding timing to reduce power to prevent cylinder cracking.
They kept promising the problems were fixed but each generation was as bad
as the last. The reason ECI and Superior came to be is in part due to what
Lycoming and Continental were producing. The ADs against ECI and Superior
are insignificant compared to some of the Lycoming ADs. ADs don't tell the
whole story, in fact as far as long term reliability is concerned they tell
you almost nothing. Only when a problem becomes a safety factor does it
have a chance to become an AD. Cylinders wearing out in a couple hundred
hours will most likely not generate an AD.
