New Cylinders....which ones?

[sstocker31]

About to pull the pin on 4 new cylinders for my narrow deck O-320.
I had my mind made up about a month ago on which ones to buy, and now I'm waffling.
I won't tell you now which ones I had decided on, but will tell when this thread peters out....

I don't fly it alot, 25hrs/year, but it is in a dry climate and hangared.

ECI
Superior
Lycoming

Which of these would you choose, and why?

[turbo]

had 2 engines with lyc cylinders. never had a problem in almost 5,000 hrs.

I chose Lycoming cylinders for my rebuild over 900 hrs ago. No regrets.

+1 for Lycoming

I have had all three brands in service among our fleet. Don't have enough hours on the Superior's to comment on them, but haven't had any issues (and this was a ten year old "new" engien that had been in desert storage). The ECI Cerminils I had for 1400 hours had a ring delamination problem, and frankly never had very good oil consumption - about 6 hours to the quart. Shortly before I replaced them, I broke in the all-Lycoming engine on our RV-3, equipped with stock Nitrided cylinders. They broke in at the two hour mark, and have run about 25 - 30 hours to the quart ever since (580 hours). So....when I needed new jugs for the Val (the one with the Cerminils), I ordered four standard Lycomings from A.E.R.O. And have been very happy with them.

Quite a turn-around for Lyclming since the late 90's when they had huge (bad) quality issues on their jugs. I thank the competition from ECI and Superior for brining Lyc back into the quality fold.

On my third full set of ECI recall cyls in 500 hours...... Never again!!

Even if they give them to me again. They did break in in just a few hours, and use less than a quart of Phillips in over 30 hours.

My Millenium cylinders by Superior have performed flawlessly from day 1. Oil consumption is absolutely consistent at 1qt per 31 hrs. I'd get them again in a heartbeat.

Just curious what generation of cylinders these are? Thanks, Larry

ECI had just lost all credibilty. Forever!
Got bought out cheap...

I have flown engines with new ECI, Superior and Lycoming with great results on all of them. Our RV-10 had ECI's with wonderful results for 1300+ hours.

Right now, I think I would go with Lycomings, but it's a hard choice.
