Default New ECI cylinders, need advice

Have a set of brand new ECI cylinders coming today. The factory is telling me that the rings come all gapped and set and the piston is already installed in cylinders, so all we have to do is drop in the pins and mount them up.

My mechanic says we would still like to pull them out and check everything with the rings before mounting them. I will speak to the ECI factory today, but wanted to see if others with engine experience have some input on this.

As far as I can tell, ECI is the only cylinder mfgr who does it this way.

It won't hurt to check them.

My ECi rings, bearings, etc. were spot on.

20-years ago, I took a new out of the box Superior cylinders and did exactly what your mechanic said. Everything came apart and was measured. 5-years ago, I took a set of ECI Titan STEEL barrel cylinders out of the box and bolted them right on to an engine.

An OLD FAA inspector once told me "Trust but verify."

IMHO, both methods are correct. IF something is wrong and you do not check, it will be a short time and you will know that it is wrong.

Default FAA 8130 tag

I bought 4 new cylinders from ECI which came pre-assembled (rings gapped and installed into the cylinders) for my IO-320. I called the ECI folks and they confirmed the rings are gapped and indexed per OEM specs. These cylinders were assembled by an FAA PMA'ed facility and had 8130 tags. As an A&P IA, I typically will use the FAA 8130 tag as a sign of some level of competency, safety and quality. I put the cylinders on as is without disassembling them and I had no issues. Compressions after 5 hrs were all 78/80 and oil consumption has been 1/2 Qt per 25 hrs. The potential risk of damaging a ring while removing and re-installing the pistons is about equal to the ring already being damaged, incorrectly indexed or inside down.

Default 8130 Tags

When I send a cyl off to be overhauled by a FAA approved shop and have them
put the rings on, install in cyl, sign it off, pay a small fee, it's done. They do it
all day long. This has to be a cousin of the Wellington effect.

I bought a set of ECI cylinders less than a year ago. I took them over to Performance Engines and had the pistons changed to 10:1's. We used the same rings, everything. All the rings were spot on when we fitted them. The cylinders never burned any oil. Probably a waste of $ to take them apart.

I have a set of six ECI cylinders for sale. They have about 450 hours on them since 4 new and 2 rebuilt per ECI recall.
The cylinders were sent new to Lycon where they were port and polished and had 10:1 pistons installed.
The cylinders were overhauled due to delimitation of rings 60 hours ago but did not break in correctly and so will need to be honed and re ringed.

Make an offer, the Lycon work is impressive.

Default Thanks all

I did just hear from ECI and since these are new PMA cylinders (not experimental) they will come with an 8130 form which confirms that they are ready to install. Thanks for the inputs.

When you go to slide out the piston to install the pin, go slow..... the oil ring is just above the pin hole, and it will pop out.
