Pull the engine! Did it break? if so would be wise to check the bearings.
you can remove the pan in the car and change the shaft but it isnt that easy!
If it didnt break dont bother.

No the only thing you will hear is a engine sieze completely while running! its an awful sound lol.
Other than looking at the bearing there is no way to tell if they are hurt!

If the oil pump shaft broke and the engine ran for even a half second I'd bet the bearings are history, all of them......

My car ran for a couple minutes with no oil pressure, and my bearings were fine.

I love assembly lube!

Yes jsut becasue you lost oil pressure dosent mean its bad, just take a look and be sure!
To really hurt the bearing they have to get hot!

Hey Adder, if it ran 'for a couple of minutes' with no oil pressure, how did it sound?
Must have been a hell of a racket.........
