I was going to say what difference does it make but I then realized.....a lot. a wrist pin is a head removal; a rod bearing just the oil pan.

I never had a bad wrist pin. Have replaced mains and inserts however. The engine bearings take a heck of a lot more abuse and move a greater distance as compared to the wrist pin; and are much much softer.

Here I'm going to suggest you drop your pan for an investigation and I have a 4230 that I am worried about maybe some worn bearings and I won't drop my pan....Oh well, I'm human.

Read a couple of days on the site where a person said he knew what a wrist pin sounded like. I know mains go gong gong gong under load. Don't know what inserts sound like .
