HELP with ARIAS pistons/rings

[krikra]

Im putting my new engine together. Using Arias pistons. They came with rings but no papers explaining ring preparation and installation..

Emailed Arias and Atomic speedware several times but no answer :roll: :evil:

Was hoping someone on here could help me.. One ring is black with "N" stamped on one side. The other is steel with no markings.

Need to know whats top ring and whats 2nd ring??

Do I install with the "N" pointing up??


Arias recommends the following ring end gaps:

Top ring: .018-.020”

Second ring: .012-.014”

Oil ring: .020” minimum on rails.


But others recommend to gap the 2nd ring bigger than top ring. Has to do with compressed gasses being caught between the rings. A bigger 2nd gap will allways allow the gasses to escape..

Do I follow this theori or as Arias recommends :?:


Please speak up

yeah I know. That would be the easiest thing. But the thing is Im from Denmark and Im not used to speaking english so that makes it little harder to communicate with you guys over the phone.. :roll:

writing english is easier to me

just heard from arias.. after waiting a week. It clarified my questions.

still not sure if I should gap 2nd ring bigger than top ring. Guess its a question of who you believe the most..
