what could have caused this??
ok this is a new one to me. from what i can tell this piston did not seize rather just broke off.....if you look at the pic the ring is bent and pushed towards the top of the piston almost as if it hung on something ( im thinking maybe the exhaust valve )?? if anyone has ever seen this please let me know. also this was a new cylinder that was put on 55 hrs. ago. at that time wave eaters were also installed and new pistons and rings from what i was told when i bought the ski....any ideas as to what could have caused this?

yes it has wave eaters installed. is this a common occurance and if i go with gas valves after rebuilding could iy also happen again?

one more thing, im almost 100 percent sure it has wsm pistons in it but when the pistons are are tdc the feel sloppy, like side to side sloppy like the rings arent seating right or the piston is too small and this is on every cylinder. and these pistons have like a rough surface on top, kinda like small bumps instead of being smooth.....what pistons would you recommend putting in here.....on a side note, before this happened i happened to check compression and all three cylinders had 120 compression.

i included a pic of my powervalve. its dirty as crap in there, looks like water mixed with grease....can you tell by the pics if i in fact do have wave eaters on it...the powervalve is working normally and nothing is broke??

It looks like you have no clips installed and yes it looks pretty dirty in there. My guess it that the piston got hung on the valve.

You have the wave eater couplers installed - but it looks like the clip was not installed. Can't tell from the picture, but is the PV pin in place, or is it missing?

when i move the cables the valve moves in and out so im gonna assume the pins in there
