Just in case you haven't heard, recent conversations and google searches have brought it to my attention that ECI cylinders are garbage. Just so you know...
I just flew a plane from Dallas to FLL and found out after the fact that it had a cracked cylinder. WTF.
'zakly. Until exhaust gas widens the crack enough to blow a hole in the cylinder head. 1500° gas at 1000+ PSI is a pretty good blowtorch for anything else in the engine compartment. Not sure what the time frame is from first crack to hole in the head though. As far as finding the cracks, word has it that spraying soap solution on the cylinder head while doing a standard compression check works pretty well.Depending on where the crack is and the size of it you wouldn't even notice.
Sounds ECI could be due for a lawsuite here soon.

That's exactly why it's so concerning. If you noticed it you wouldn't fly it. Ironically, this particular jug had the highest of the 6 on the motor at the last annual (only a couple months ago).
Not this round. The ones my friend has been seeing on ECI Continental jugs originate near the top spark plug hole and seem to migrate over to the intake valve seat. At least, that is what he said all the cracked, but not blown out jugs had done. After the bubble trick a small oil line was visible between the 2nd and 3rd cooling fin inboard of the fuel injector nozzle winding its way down the side of the cylinder. None of these (other than the one that totally failed) showed any indication of cracks on the exhaust side of the cylinder, which is quite odd considering it is the hottest and most highly stressed part of the cylinder. I doubt he would let me share any pictures, some companies are awful sensitive about stuff like that getting out to anyone other than the proper authorities. I might see if I can get some just for my own education though.The ECI Lycoming cylinders affected by the AD crack around the cylinder head where they screw it onto the barrel, that's why you spray soapy water onto the joint, a cracked cylinder blows bubbles.

Screw recips. I wanna work on turbines.pulled two TCM cylinders off today for leakage past the exhaust valves with barely 500 hours on them.
