Unless he has a modded or B series engine, I doubt he has the piston squirters inside the block. Those help to lub the pin, skirts to prevent seizing.
Otherwise most engines the pistons under side is lubed by splashing from the other parts. Kind of like how a typical lawn mower engine is. Thats why for those they have what seems like a high idle to allow sufficient splashing for lubrication and air circulation to keep it cool.
