My friends sled has antifreeze in the middle piston. We pulled the head and found broken O-ring. so we replaced it and it seemed to run good. We took it out for a rip and found ity still has coolant in the center jug? Anyone with a answer. The head seems flat. I have not pulled the jug yet maybe a crack?? We did a compression test and the were all the same. I don't remember what it was I want to say over 100. Any help? Thanks

Double check the o ring again, use astraight edge for warpage on the head and also check for cracks and correct torque of the head bolts
Good luck
