piston and cylinder destroyed photos what now ?
Got the head off today and found cylinder 2 piston trashed and head has serious pitting , wave eater clips installed so how did this happen ? Looks as though Pv area was impacted , now from photos how much parts am I looking at ? Piston moves as it should but what about all the metal pieces ? Lol

It is still possible for the power valve to fall down even with the clips. I would contact Mike at pwcengines.com. He has always been fair with me.

Usually happens from a lot of hours on motor, and piston alignment pin fails causing the ring to rotate around and catch the port. I would tear it all down and inspect. Crank may have debris from the damage
