I'm asking this question for a friend who's building a big block Chevy. It's a 502 and he's wondering about the oil ring gap. (I don't remember checking the gap's on my oil rings!) He was told it should be .015-.050 and his are right at .050. Should he be concerned?? Thanks guys.

I have always checked my oil ring and that seems a little wide to me. What was his compression ring at? We once ran into a problem where the oil rings were mispackaged.

He has "file to fit" rings, so he's okay with the compression rings. He was just puzzled by the big gap on the oil rings. :confused::confused:

Oil rings don't have a gap setting. You have the expander and two rails. Just put them on like the instructions say.

LOL.. I was reading this and thinking oil ring GAP??? Haa, maybe he means the second ring. I have speed pro file fit and Ill have to look at the build sheet but they were at .022" gap, I think. Either way I used the recommended gap from the ring supplier and, forged manley pistons. JR

I was taking it as he meant the second ring. The only way I have checked expander rings is by the tension it takes to pull the piston and rod through the cylinder.

:) Yeah, from the answers given you knew what he was asking. Funny how guys that know engines can get around the computer communication mishaps without a hitch. JR
