Here is my
I dont under stand why such the extra wider ring gap for the 2nd ring. I can under stand a few thousands extra yes. But this would occur anyways. Example, Gap the top ring .020 and gap the 2nd ring .020..the top ring will see more heat and expansion by nature. That why I dont think it would hurt to gap them the same, the top ring will have a hair less gap from expansion anyways.
I have had engine slobber, blow oil, smoke like a freight train at the track, pull it apart, hone the block, file fit the rings, really give it a good work over...
back at the track, no more slobbering, blowing oil out the dip stick after a pass...Guess what though?
The car runs the same, all that was worth zero power. Its nice not to be blowing oil and to keep oil out of the combustion chamber.
The main thing is to get good ring seal, and keep them from butting, .005 in ring gap either way doesn't mean crap.
Gap them both about .004-.0045 for a N/A engine and dont look back
