When I install sleeves I leave a step at the bottom of the cylinder. Can't come down. I have seen sleeves that were had a pin thru the lower part of the cylinder that would also work. Don't trust the press fit theory.
I had another thought that the rod might be bent but just checked and it has no bend or twist. I do know the owner was going fast when it let go.

That's the way I put sleeves in and if I find a customer has sleeves in like that I pin them with 1/4" bolts and loctite them in and grind them flush outside after boring the sleeve to size. This way the pin is almost invisible and keeps the sleeve in place.
