Twice I have replaced head gasket thinking water was leaking into oil ,
last time did pressure test and checked plane on head , head was fine
which leaves me with a crack in the water jacket , has anyone tried
putting sealer in , and with a external water source how do you put it
in .
Any help would be greatly appreciated

How would you describe the condition of each spark plug?
