The pistons are lubricated from the throw off of the connecting rods. That is one reason you never want to let an engine sit at low idle speed for extended periods of time. The lower rpms do a poor job of lubeing the pistons. Many people will argue this but that is beside the point. The ones that argue will be about the richer fuel mix at idle and there is merit in that but fuel injected engines rule that argument out. I learned early on in engine rebuild school that just the wrong radi on a crankshaft crank pin can effect the throw off of oil and lead to oil consumption. Far as the wrist pin, the same thing applies when they don't have squirt holes which none of the internationl engines have. Throw off is collected in the champher above oiling hole on top of pin end of rod. IH had drilled connecting rods in the earlier years up to maybe in the 1950's but found they had more wear that way and more piston failure than with splash lube. You can also see why excessive clearance or not enough clearance on the rods can effect oil consumption of any given engine.
