I'm new to 22RE engines & in the middle of swapping a rebuilt 22 RE with a 22R in an 84 PU. I was cleaning up the timing cover from the donor truck & couldn't help but notice wear in the oil pump area. Is that normal for this engine or should I be looking for a new timing cover?
Also how critical is it to use a new oil pump & water pump. I see nothing wrong with the old ones, but if money were no object I'd put new ones in. Unfortuneatly I didn't just win the lottery, & am getting the truck ready so I can go back to work after a long dry spell.

What would you do?
