Pulled the motor tonight on my kids 08 Crossfire 5, to do the water pump seals and do a top end on it as well. Compressions was on low side, 110 on mag side, 105 on pto side using a top of line princess auto gauge, lol. Pto side has some damage, I have tried attached a couple pics. Anybody got a diagnosis? Is the cylinder repairable in this condition?

Scrub it with a scotch bright and muriatic acid. It will take any aluminum off the face, then you can see if any of it is actually cut in.
