[Shotimes] Rod Bearing Confusion

[sho2go]

When I changed mine, at 150K miles, the center 3 had a little copper showing
on top.  2 used oil analysis showed increasing copper over a year, so it was
obvious.  Copper has since gone down, so I am assuming the mains are ok.
Code was D9C.  On another note, its difficult to tell what the clearance is
using plastigauge unless the engine is horizontal on a stand so there is no
gravity or other undue forces on the pistons, which is how they should be
measured.  Having said that, if you have a knock where there wasn't one
before, a bearing might have been incorrectly installed, in which case it
will eat the crank in short order.
