I'm curious, how would blow-by lead to shorter engine life? I understand how it could reduce power, but it would seem to me that greater clearance on sealing surfaces reduces seal wear and would increase engine life in exchange for maybe less fuel economy.

Didn't Mazda increase side seal clearance drastically on the Renesis? They must have done that for a reason, right? I personally would trust Mazda engineers to have better data than the entire engine builder aftermarket put together.
