If it's white smoke it sounds like water.... but sometimes easily mistaken...
My theory on the pumps is (and i'm sure others will other views), but the left side pump sits in the front of the head with its vent line to the AOS also near the front of the head at the top; the right side head vent and pump are directly at the read of the head below the AOS... so when you accelerate and or make a left turn at the same time the oils gravitational forces push it directly into the right rear vent area (causing more oil to accumulate right below the AOS)...
So if one of the pumps isn't performing correctly its likely to be the right side (cyl 1-2-3) as oil accumulating under the left side vent is less likely during acceleration.
The pumps are the same, and they are easy to swap... *you just have to make sure the label on the pump 1-2-3 is facing the block on the right side and 4-5-6 on the pump is facing the inside on the left block. I've seen these get installed backwards which causes them not to function... you can try swapping the two pumps to see if the problem goes away....
