John,
I went with ECI Titan's two years ago on my IO-520. These are the
nickel ceramic cylinder bores (lots of cold damp winters here in Michigan).

I've got over 150 hours on them and so far so good. Broke in well.
Compressions are good. Used about 1.8 qts in 50 hours.

I've heard that Continental has 'supposed' to have solved their cylinder
problems, but, to me, its a little like: "You just got out of the State
Penitentiary but you say you've reformed, and now you want to date MY
daughter?" I'll wait until a whole lot of people jump into the water first.

One vote for ECI.

The IO-520 out of our Cessna 210 is being overhauled by Custom
Airmotive in Tulsa. We had wanted to go with new Millenium cylinders,
but Superior has a halt on shipping them. A Superior rep said there
were some minor design changes that the FAA is requiring them to run-
test to assure life to TBO. They have not been shipping any of these
cylinders for 60 days or so, and said that the testing would likely
require another 45 days, resulting in shipments resuming in late
January.

I have seen that Millenium vs. ECI vs. Factory (Continental in my
case) has been a perennial topic here but not lately. My current
decision basically boils down to "wait for the Milleniums" vs. go with
ECI. Does anyone have recent experience or recent information about
quality, reliability, etc, between those options, or other options or
thoughts?

Thanks,

ECI isn't perfect, either. Some of their jugs on certain Lycomings
have been AD'd. See
