the best oil in the world won't repair damaged metal parts. They try that at work all the time, trying to change the oil or greasing bearings after the damage has been done. You can just try starting it if you want. I wouldn't, but that is just me. I would make sure there is no damage before I dumped in $60 worth of break-in oil. (I bought 6 quarts of brad penn, a filter and some little doodad, came to $83) Perhaps you are independently wealthy and don't care about the money part. Whatever you decide to do, I hope the best for you. By the way did you read the break-in procedures from the cam manufacturers? You really, really need to do this.
