I also looked atthe log when it happed, the a/f boost was all normal.
I didn't think we had a balancer either. The only chain I can think of is the timing chain, and you'd know if that broke. If the pulley's on right, the next thing to check would be the flywheel. It's got to be either something spinning or something making contact where it shouldn't.
