What Prine said!!!
Under boost more heat will cause more expansion therefore causing butting. This in turn will cause the ring to seize to the cylinder wall.
I used Total Seal and confimed with tech that the .055x bore is Not sufficient. I went .028 on the top and .024 on the bottom and .015 on the oil rings.
I did alot of research as regards which ring gets the larger gap on boosted engines, and found about a 50/50 split on opinions regarding putting the bigger gap on the second ring.
Anybody got any solid knowledge on that issue???? :study:
Well the pistons aren't anything special just stock replacement. Still not sure who makes the rings but whatever is standard in a rebuild kit which is just federal mogul I think. I'm only gonna be running 8-10 psi regularly and maybe go to 12 someday once I get a hang on the tuning aspect. So is this enough to need to gap them? I guess I should measure them n go from there.
