Ideal ring gap position
Turbo Mini Forums

Building my NA 1380 Twinky now... fitting forged Omega's from MED.

Guys, what position for the ring gaps do you advise me for this engine? All in all they should create a labyrinth for sealing, thus every ring should have its gap as far as possible from the next ring its gap.
Just checking some pictures on the www give me more cunfusion than conviction.

Please advise, MED stays silent....
many thanks, Bart

Totalseal gives some recomendtions on this if i remember correct, but they will rotate around...

Don't worry about it, they don't stay put and it won't make any difference whatsoever, old wives tales.

yeah stagger them about 120 deg but not critical as they will move

thanks all for taking away my doubts!

Just dont gap them too tight !

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Echoing what stevieturbo said, There's also nothing wrong with a ring gap that's a bit slacker than the ideal tolerances. I read an article a while back about ring gaps, and up to a certain point it has no effect whatsoever, the gap it did start to affect things was a pretty damn large gap if i remember correctly. The ring gaps in the 998T were larger than specified because of a rehoned original bore block, it's been perfectly fine and covered many thousands of miles, the bores looked perfect still after about a year.
