Crap Crap Crap

[_Cheese_]

Well im building up a 5.0L. I installed the crank after it was ground down 10 thou, I was installing the pistons when one of the covers that go on the rod bolts fell off. I didnt notice and sure enough it made contact with the crankshaft... It didnt look like much.
I put the connecting rod cap on with the new bearing, put some assembly lube on it, bolted it to the rest of the connecting rod and spun the crank a few turns.I removed the cap and felt the bearing with my finger nail. It did remove material...bearly enough to catch my fingernail.

Do i have to take the crank out to get machined.. again? Or would it be ok to contuine on with installation?

Whenever I mic a crank and all the journals are good (no taper or out of round) and I can re-use it without having to do any machine work on it, all I do to clean them up is take some 600 grit emery cloth to them. This is all you should need to do from what you explained. But if the nick is pretty deep, you may have to have it machined again. When something nicks a steel object, it pushes metal up around the edge of the nick... the low spot on the nick is not harmful, but the raised edge must be sanded down smooth with the emery cloth so it doesn't dig into the bearing surface.

go get some real fine emory cloth from lowes and buff it out. this happened to me when i put my engine together. mine was a pretty good knick too. i buffed it right out and my engine hasn't blown up...... yet!
