PISTON RINGS GAP

[RAYMOND259]

I bought some Seal Power E-251k 30, the rings gap is .011 on both of them is that normal or not?thanks

I can't remember,
Every time I have purchased rings they have come with a guide sheet for file fitting the gap.

I still need to file fit my rings, so I am subscribing.

Open them up to .016"-.018" N/A
Or more if you are running n20/boost. (.020"-.024")

I set top one at .016 and how about 2nd rings around .020 maybe.thanks

That will be fine, and gapping the 2nd ring larger is the new theory as well...it will help keep the top ring sealed and prevent ring flutter. Just make sure they are square and deburred very well...

I assume this is a NA combo??

Just FYI-
I gapped my rings today per the sheet that came with them. Suggested was .016-.018 for the top, and .020-.022 for the second.

I think I hit under .017 on the top and under .021 for the second on all cyl's.
