Why do I have piston ring bits on my piston? #1571433 01/31/14 04:58 AM 01/31/14 04:58 AM

He called me(yep I was freezing cold!!!) and he went a new best on motor, Picked up .3 and 4mph . I told him to watch out as the end often comes after a great pass. Then he calls to say something went wrong while purging before a real best pass. He takes the head off to find piston rings on top of a piston. Can you help diagnose this issue? Maybe thinking we could get another year out of a junkyard core engine caught up with us? 8019397-360012.jpg (239 downloads) Last edited by goldmember; 01/31/14 04:59 AM.

I dont know
