results of bearings after oil pump lockup

[90_Red_LX]

Pulled the motor out of the car, and pulled the pan along with the oil pump off. Found the pump shaft, pulled it out, and pulled the oil pump. Oil pump is locked with a small foreign piece of metal in there. Pulled main bearings 2 and 4 out also. #4 looks real good, only minor scratches. However, #2 has a copper groove in it that you can feel when you run your finger accross it, and a small copper spot along the side. How bad off would this bearing be if it was put back? I plan on pulling the rest of them and investigating them all, but could this motor go one more year? The car isnt a daily, even though I use it for it sometimes to drive it. I have one more year until I am out of school, and I can build it the way I want it. Right now Im in a bind. Let me know what ya guys think. Before the head and cam swap, she made around 25 at hot idle, and very good at anything above idle. With the head and cam swap she improved a little till the oil pump locked up. Should I let her sit for a while or try her out and see how she does? Lot of work pulling a motor though. Thanks.

PS: If pics will help with judgement of bearings I can get em.

Bearings aren't that expensive. Since you already have the engine out I would put a new set of bearings in.

Dude, I'm sorry man, I didn't know that occured That sucks...

Well I'm sure you know that it is more than just putting in new bearings It adds up quick...

Good Luck with whatever you do and can afford!

well in my opinion for the 150 bucls or so it would cost for the new pump and gaskets and bearings it would be alot better then putting it back together and and with old bearings the wast of time it really would be to put a motor back in ur car for the short time and chance damaging alot more.

Add in assembly and polishing crank (or turning if need be) and ridge reaming/honing as a possibility. It adds up...

The rest of the bearings have a spot with a slight hint of copper, with one having none at all. After thinking about it for a couple hours, I believe I will just put it back together as is, hope it makes oil pressure, and runs ok for a while. If it doesn't it's going to sit for a while anyway, so I'll just leave it in the car.

Likely you can add a new crank to your oil pump and bearings and 2 sets of gaskets if you run it that way...

ok maybe i wasnt very clear i was meaning that if he was goingto just do bearings and a oil pump he would have about 200 bucks in it because i know here in nc it only cost 30 me 30 bucks to have a crank polished and about 60 to turn it if need be, but thta would prob be the quickest and easyest way for him rite now if he is only wanting to get by for another year.

dude, at least put a new set of bearing in! They are cheap

If the crank has marks in it, it is useless to add new bearings, it will actually make it worse and he'll be in the same spot he was. 25psi at hot idle for a stock 302 is a little low. If you add a new puimp I would add a higher volume model, run some thicker oil....

The cranks polished finish isn't 100% scratch free, but from what I have seen there are no marks that you could feel with your finger. Granted I haven't spun it over yet either though. I'll probably inspect the rod bearings next. I was informed to mic the rod journals for roundness and wear, then get a set of bearings for the rods along with the main journal bearings. That would be the way to fix it for cheap. If the thing would just hold up one more year I'd be happy.
