    If you have a SCer failure, major/minor H2O hydrolock, crank the engine over with the plugs in and rockershaft off, over 100 hours and rebuilding engine, I would replace the timing chain.

    a little bit off topic but what are some scenarios that can cause the timing chain to break(besides lack of oil)?? saw two of my friends skis that broke their timing chains..

    Usually after a ceramic or metal SCer washer failure. Guys just pull the engine clean it out as best as possible, change oil pumps maybe and reinstall. The only way to inspect the chain is to pull the crank and at that point you may as well change the chain. I know two friends that had the engine cleaned out after washer failure by SD techs and lost timing chains withend 10 hours afterwards. One was a ceramic washer failure and the other was a 08 metal failure.

    It happen to my ski at 8500rpm. The timing chain snap causing lots of damages. Crankshaft Gear, Balance Shaft Gear, Rocker Arm, Fly Wheel, Exhaust and Intake Valves all gone. The only part save was my 2Rude Charger and Riva Piston (TG). It was very sad when the cover was pull off and see piece of metal falling everywhere. I have to replace all these parts.......It wasn't fun anymore for me!!!

    Only thing I did notice was some bearing scratches on the cam and head machined area (smoothed these out ) , maybe I over torqhed the cam causing it to have more strain on the cam rotation causing the chain to go boom, Im hoping no major damge cause it was idling when it happened il post some pics of the carnage .

    well got the motor Out and apart and it had a broken rocker arm with a peice lodged in there that caused the valve train to lock up is this common for a rocker to snap off ?
