"It seems kind of unprofessional, but is it ok to just grind that one journal undersize and put the correct bearing in and leave the rest STD if it comes to tearing the motor down?"

YES!! ABSOLUTELY. Go look up the word "professional" that always seems to get tossed around this web site alot. Basicly it is someone who does something for MONEY! It does not imply they really know what they're doing.

Much of the machining work that is done on engines is completely unnecessary. I've had one hell of a time over the years with cylinder heads. If i take one to automotive machine shop for guide resizing or grinding because they are so bad i have to be very emphatic that i want ONLY the work done that i have requested and NO OTHER work done. On a few occasions some shops will try to push a lot of unnecessary machine work such as milling the head and sneak it in. Then whein i walk into to get the head they say "oh, by the way..." and extra bucks.

So much of this so-called 'professionalism' is just building time and padding the bill for work not needed. If u work in a new car dealership or any automotive dealership then u are aware of "writeing up time". Same difference.

I've got a 2.0 ranger currently in my possesion with hand polished rods and mains (NEVER Ground since factory) at 150K ruff miles. It now has 180K miles. I have another one down rite now. Several out there running over the years with little or no problems. Some that had only one or two journals professionaly ground because they were too bad to polish out.

The journal does not have to polish out to perfection. Just do the best u can with it. I can't see it. Maybe really does need to be ground. It is a judgement call not ez to make without direct inspection.

Give your plan a try.

The only other propblem u will run into is trying to find a store that will sell u just ONE rod bearing pair. Everyone now wants to sell a god damned set or 'kit' for everything.

I went over today to buy 2wo pistons and could only find one store (advance auto parts) that would sell me just two. But i have to wait a week for them. Not a problem. And they were cheaper (each) than a set (each).
