I'm probably a little late posting these pictures but I have been looking at the crank oiling and cross drilling recently.

This is an MY06 JDM 2.0 STi Sec C crank.
It's crossed drilled and nitrided stock

In these ones we have an EJ257 crank on the left, Spec C in the middle and an early EJ20 crank on the right.

Ever since I took these photos and looked at an aftermarket cross drilled crank I wondered why they only cross drill the mains.
Does anyone have any idea why they wouldn't bother with the rod journals?
