Clicking sound from crankcase
I'm currently rebuilding my 01 ski doo formula deluxe 600. With the cylinders off, if I take the rods and alternate them to turn the motor over, it makes a weird clicking noise. It sounds like a little metal ball rolling around in there.
The sound only comes up when I'm spinning the motor at a decent speed. I have used a magnet and compressed air and can't find anything. Is it possible the noise is coming from the flywheel side, possibly the stator? Is this a sign of a bad crank bearing? Thanks
