Liner O-ring failure

[Mr Hagg]

Interesting for sure. WHen I look at the brass shim here I see either signs of combustion gas or sludge from mixing coolants or something. What does top of pistons look like? What does inside liners look like? You see any heat marks on inside liner? The first few things I look at is friction how was piston and liner looking? Was there heat internal that maybe ECM didnt see? Which would lead to looking at tuning first see what kind of power we trying to make. Look at tops of pistons to see if you see the spray pattern? Was it flashing the liner on top of piston? I wish I could point you into the know but what we have thus far we can only speculate whats going on.. Please post more pictures, top of piston, inside liner, maybe more than one cylinder. Also what do the rest of the liner orings look like?
