had a problem in the last reac of the season where the bearings collapsed in the turbo sending fragments into the sump and then through the engine. all bearings and crank were to throw away. anyway... the BE oil pump has some small marks where some material has made its way through. do you think the marks could be dressed and the pump will still be ok to use? otherwise i have a brand new standard pump. you think this would be ok at 400bhp? the engine does have an ATI damper.
thoughts?

For a dedicated track car I would put in a whole new BE race pump. After personally dealing with oil pressure issues, I will not hesitate to make sure I have a new one in any motor that has seen any sort of metal going through it.

Don't be stupid. You're risking another $3000 motor over a $400 part. What you probably can't see (and haven't thought about) is the scoring in the bore of the relief valve which will cause oil pressure isues. Replace it.

If it was going into a street car I would 100% agree with you. Since it is going in a car that will spend a good amount of time on track, I have to agree with Savington, that a new one should be ordered and installed.

I work with UHV pumps everyday and my opinion is that you should call the company and ask what the tolerances are for the gears. Those marks may be smaller than the tolerances of the tooling for machining. An oil pump is not that complicated and oil is viscous. If you can polish the marks out and still maintain the proper clearances it is probably fine.
The bigger risk if those marks are bigger than they look is that you created stress risers all over the gears or bent them. Have your machinist measure everything before you decide.

Nicks in gears will make more little forged steel pieces/shavings/chips/glitter travel downstream, maybe into the relief valve, turbo bearings, etc. On an N/A road car, yes, but a high strung turbo track car, never.
