I'm just reading up trying to learn a few things about my engine, and I wanted to see what exactly the stock rods where made out of. so what my question is, is what exactly does "connecting rods and rod caps are initially formed as one-piece powdered metal forgings." I "powdered metal" is what im confused about. if someone could clear this up for my that would be cool, thanks in adavance -Jack
Pretty much. Then, to form the rod cap, they crack the big end in half.

It's intended to lower production costs. There's nothing, inherently, wrong with the stock pistons in these cars, but common sense would tell you what happens to strength when cost is reduced.

The biggest problem with cracked cap rods is the headache they give engine builders when trying to hone/resize the journals if they go out of round. I say headache because it's damned near impossible. Hence another reason to buy H-beam rods when rebuilding.
