Thats crazy, so now your telling me this engine was run with the wrong balancer?? I wouldnt imagine that would be too good?
Now that I think about it if it were for a forged crank wouldnt it also have the rubber ring separating the two halves?
Also wouldnt I be better off finding a new one assuming they are avail? Ive had problems in the past with that outer portion slipping and causing issues when going to time.
