Re: Piston/Ring issue???
It's possible there is a small radius at the bottom corner of the ring groove. If the rings have a sharp square edge, when the seat in the bottom of the groove this could cause this rotation problem. This could be as small as .001-.002 radius and not visible to the eye. Is there a chamfer on the inside edge of the rings and spacers?
Interesting, keep us posted. George |
