connecting rod clearance

[1turbo6]

what would cause the rod to eat into the side of the crank? 100-150 miles and there is a knock. scat rods on a fresh 10/10 crank. was told rod journal side clearance was .017 on a couple. but now 1 is at .035 what would cause the rod to want to pull to one side? and wear the bearing on the other?

Bent?
In backwards?
Twisted? [Pin c/l and brg end c/l not parallel]
When the crank was reground, was the journal width correct? [What was the side clearance on ALL 6, when the engine was assembled??]
All 6 rods the same width at the big end?
All rods have the correct chamfer to match the crank?

are the rod chamfers supposed to be the same size on both sides?
