Left Bank bent all of the exhaust valves, broke the cam chain, and peeled the teeth off of the exhaust cam.

Chains from Heads to IMS are still intact. (they don't move with the crank) Removed heads and IMS bearing retainer. Crank turns, back of IMS turns. So the crank to IMS chain is intact. Appears I-shaft is no longer connected to the crank drive sprocket?

Is there a keyway, spot weld, shear pin, flat spot??? What connects the shaft to the drive sprocket?
