Re: Isolated Cases of LS2 Oil Burning...
Your comments agree with my assessment that over-size pistons are the answer, even if I arrived at the conclusion without that knowledge. Maybe there's another option...I wonder if you can get some good old fashioned, non-green, non-low-tension, conventional piston rings for the LS2...maybe with a self-honing, diamond dust coating? Aw, those diamond encrusted babies would probably stop the oil burning for a little while, then it would come back with a vengeance as the pistons began to rattle around in the bores.
If John doesn't know the General is doing at St. Catherines (sp?), I certainly don't know, but it seems the cylinder bore requirements of low-tension rings would force all manufacturers to use the deck-plate honing technique with the low tension rings, or potentially face high customer complaint rates and warranty costs. Anyway, it isn't happening often...maybe it's just the normal failure rate for on-the-edge technology.
