115 hours on New TMX-0360
3 out of the four were broken. Only one was in two pieces. The safety lock for the nut held the parts from separating and falling down on the other two.

Gil, do you know what the part # is for the bend up tab lock washer that holds LW14995?
Thanks

New problem
Instead of the clip being the problem. It was actually the can follower which failed about an inch and three quarters from the end (clean break). This forced the push rod tube out and caused the clip failure. This will cause a full teardown to my "new engine". I will be contacting ECi about this as well as Mattituck.

When you say cam follower, is that the same as lifter? Do you have roller lifters?

Only one broke.
It broke about 1/4 inch below the groove. Got to be something else wrong or some bad metallurgy somewhere. I guess I'll have to wait until the case is cracked. There have been no unusual temperatures, speeds or other symptoms. Only the Shadow knows! I consider myself fortunate.

another failure
While removing the cylinders from a friends ECI O-360 (group B cylinders), we found 2 of the 4 shroud tube springs broken. Tubes had not moved--no oil leaks. Total engine time is just over 85 hours. I think I'll replace mine with the lycoming part before I put my engine into service. As stated above the Lycoming number is LW-14995 and don't forget the LW-12272 lock tab.
