The other night missers rang me up said the car broke down so i got it towed home. Opened up the rocker cover and the cam isnt rotating. On closer inspection the bolt on the RHS of the cam has snapped clean. On one of these engines, would i have done damage to the valves? Im just trying to see if its worth putting another cam in, or would it be pointless because the bottom end will be f**k....

PLEASE HELP
thanks.
