Defective cylinder kit, Lyc IO 360

[garytex]

I recently purchased two new Lycoming cylinder kit's.  One ran very very hot 400 to 430°F.  Turned out it was 6 thousands out of round, and had 15 thousands choke. 

 Turns out Lycoming has no spec for choke on those cylinders. Although all cylinder rebuilders think that 8 to 10 thousands's is where it  should  be.

 I paid them for a third cylinder, it  runs  OK and theoretically they will credit me back for the bad cylinder and pay some amount of money to my mechanic for changing the cylinder .

Jetdriven, sorry I couldn't respond to your PM something wrong with my iPhone to blog connection.  Besides which, everybody should be watching for out of round cylinders, this is current production stuff.

I have some other things I'd like to visit with you about. Please call me  when you have a moment. 512-923-1904

 Thanks, Gary

Now that Lycoming has perfected camshaft and lifter failure, they're moving on to cylinders.  When an entire engine costs more than a decent car you'd think they would be built with proper parts.

I bought a new cylinder after my head separation incident last February. The pre-install measurements were fine. It broke-in nicely and I have had no issues.

Oh, this is nothing new for Lycoming. 10 years ago we purchased 6 brand new cylinders, 4 of them had near zero compression after 30 hours. 

They warped horribly.

This doesn't say much for the "certification costs" they all like to rave about when the price of their products are queried ...

The engine shop who rebuilt my engine back in 2012 also told me that it was not uncommon for them to have to machine brand new cylinders to get them onto spec, before they are able to install them.

Just an FYI. I saw Aviation Consumer just opened a survey for satisfaction of cylinders. Might be worthwhile to voice your opinion: http://questionpro.com/t/ABQbdZS511

I was told by an engine builder in Clearwater that he must always carefully inspect every part that he receives even if it is new because he often finds poor work.  Sucks when you pay so much money for a rebuild kit on an ancient low tech engine and the parts are shoddy.

Ain't it the truth

All the more reason to overhaul what you have vs. rolling the dice with new stuff these days from Lycoming.  Really sad.

ECi is now owned by Continental and saying that ECi is going to stop producing Continental PMA parts.  At the same time they are going to ramp up with new PMA parts for lycoming engines and possibly even offer a complete certified lycoming clone engine. 

[jetdriven]

Superior makes a lycoming clone for experimental a but I wonder how you could build a complete clone for a certified airplane  without a serial number from Lycoming.  

[N601RX]

I think it would be an ECi engine with an ECi serial number that was a PMA replacement for the same lycoming engine.

I have a customer with a Comanche 180 which had its engine overhauled with a complete new Superior kit.  After assembly the Lycoming data plate was transferred to the overhauled(new) engine.

But you'll have to get the lycoming data plate first, I think.  I've seen PMA replacements for components or accessories but not an entire engine.

His Lycoming was beyond economical overhaul, so he had the data plate and log book.  The engine was overhauled by replacement.  The total time continued but has zero SMOH.

Not sure if this type of kit is available from Superior, perhaps the new ECI/ Continental could do it as a replacement Lycoming.

I am guessing the oil sump survived , the logs follow the data plate , its the only part that cant be altered...

Nope, the sump was new as well, supplied with the kit.  The data plate was removed from the Lycoming sump and fastened to the new sump with new supplied drive rivets.

lycoming even makes a new data plate to fasten on to the new sump as well. So truly the only thing with 2401 hours on it is the logbook. 

Actally that was new too. So the only thing that had 2401 hours on it was the legend of the serial number
