Scarred crankshaft !

[16Pilot]

I got a new crank kit for my rebuild and somewhere along the line we scarred it somehow and I wanted to know if it would be ok to use. Its kind of like a nick from a bolt or something. Question 2 is...when you tighten rocker arm nuts do you rotate the engine to do each cylinder in the firing order or is that false?

Is any part of the nick proud? If not what dimensions is it and how is it 'laying'? I'd take the crank to a machine shop and have them linish it. The rockers should be done at TDC of the power stroke of each cylinder if it's a chevvy. If it's a Ford then torque them up to book spec (20 Ft. lb. from memory).<br /><br />Chris..........

Re: Scarred crankshaft !

Have the crank refinished to avoid taking out a new bearing.The lifters can be adj.at t.d.c.#1 cyl.for half of them and the other half after turning the eng. over to t.d.c.for #6cyl.on a GM 8cyl.This will get you close.The best and most accurate is to adj.them running.
