Anyone know of a good company to repair a nicked or slightly burnt camshaft? One set of cams were damaged outside of the motor and the other got burnt due to lack of oil in the motor. The latter does not appear to be bad enough that they are worth throwing in the garbage but they need some work before they could be used again. I understand it's risky and would be better to buy new but these camshafts go for over $1000 new and would be a shame to throw them in the dumpster.
