12 o clock being the top ring? how should the oil rings be set up? and yes i know the two top rings are compression, there are two oil rings. thank you!
2 oil rings ? are you talking about a 2 piece oil ring ? if so then just set the gaps 180 deg. apart ! all the rings will move around while the engine is running ! the reason to offset the gaps is to help with initial blow by !
There should be a chamfer on one edge of the rings as well I believe. From what I fermenter the chamfer faces the top of the piston so that the conbustion gas gets in behind it and firces it out to create a better seal.
Someone correct me if I'm wrong
