Thanks. So, considering that, it makes the failure of my head gaskets at less than 16,000 miles puzzling. Can you imagine why this would happen to a moderately driven, completely stock engine? And re: the ring land problem, why would there be excessive detonation in a stock-tuned engine? Are the engines poorly tuned from the factory?

i would say that this type of gasket is likely to sweat some coolant but not quite leak in a troubble some mannor.

as for the bottem ends giving out at 100 000 miles.. not much different than any other engine . what usualy happens is turbo faillure or some other stupid thing sends debris down into the oil pan witch is then later circulated past the oil filter bypass into the oil galleries right on to the bearings.

the ring land failures is related to detonation. the best piston in the world will also die eventually if there is excessive detonation.

piston slap will be noisy at -25 deg c ! sound like a diesel truck ! but thats just the way it is.
