Diamond Blower piston rings???
Diamond uses these same rings on non boosted pistons too. The flat top -2cc valve reliefe pistons also.
what rings are the diamond ones?, i dont think they make there own rings,
I bought the Diamond piston-ring-pin kit new 4 years ago. They might be using Total seal now, but i wonder what they used back then, the rings were in diamond boxes.
I hope i dont have any problems with them, like moly , plasma, coatings comming off etc.
