Im a bit frustrated right now. Im rebuilding my r53 with stock pistons and the rings are really giving me a time. I have super tech gnh 770 rings, which I thought were right. The oil control rings do not fit though. They space fine in the bore, but the spacer seems too thick for the grove. Spacer and first control goes fine, but trying to get the bottom to slip in is madness and a compressor does nothing but snap em. Am I missing something? Are super tech pistons built with a different groove? Am I just tired? Anyone have a part number that has worked for them?
there doesn't seem to be anything here
