Silly putty is a favorite tool box item used for checking valve clearances etc.
I have heard many bad things about the cylinders, but am happy with mine.

Today I used your silly putty with mirror method that you suggested and it worked! I had only about an 1/8" clearance between cylinders so I used a tongue depressor to hold the silly putty, then some thin screwdrivers and thin metal machinist scales to press it in. Thank you T.S., you saved me many hours of work!

Yes , this is exactly what ECI told us, don’t worry about them ( two engines new in 2007 0-360 purchased from Mattituck). I would like to have had them in the back seat of the SuperCub when one head blew off on take off on floats at 90 above the lake headed for the woods. Thankfully my friends son made a safe landing back in the water. The person at ECI could have cared less about the incident but I bet he would have , had he been sitting in the back seat.We purchased eight Superior cylinders and changed them all out, you can do what you want, but don’t ask me to sit in your passenger seat with these ECI cylinders.

Ron,
Which cylinders would you replace them with?
Thanks,
John

I see now that you said Superior. I guess that there are just one model available.
Thanks.

Thanks
The pleasure is mine. Feels good to finally give help to others after all the years of taking while building.

ECi Cylinder inquiry
The serial # location on the side of the intake ports is correct and they are Group A so they do not need to be retired from service. ECi had a problem with the machine fitment between the steel barrel threads and the aluminum heads in the Group B cylinders, not the Group A.
Note that ECi did extensive research and destructive testing using a pressure rig at operating temperatures to improve the fitment and durability of the aftermarket cylinder assemblies, both parallel valve like these and angle valve too. Those improvements are incorporated into the cylinder assemblies that are manufactured by Continental Motors now for Lycoming(R) and Titan engines. The trade name for them is "PRIME" and they are available through Availl and other distributors. They are the only cylinders that are available with the NiC3 electroplated barrel surface. Standard thru-hardened steel is also an option.

Thank you for the explanation. I have Group A cylinders with about 500 hours so, with your explanation, it sounds like they are ok to fly with the inspection frequency met without substantial risk of catastrophic failure. Correct? This plane is new to me so I am just now navigating these waters and I appreciate your help.

ECi group A cylinders
Correct, the risk of a failure of Group A cylinders is very remote.
