Message :cam drive belt before hand. Go ahead and do the leak down as suggested, although if you have valves stuck open, I don't know what the test would indicate. In any case, by removing the water hoses, radiator, fan, fan clutch, CAS, igniter chip, their wiring and the aluminum water hard pipes, you will gain access to the belt covers and subsequently the belt and pulleys. You can then check for proper cam timing.
:You only need to remove the heads for valve/seat work if the valves are bent from making contact with the pistons. Once timing is corrected, do another comp check. If good, your valves are ok, if bad, remove the heads.


How do i do a leak down?
