head gasket problem

[Stew Robertson]

Hi Kevin
take the rad cap OFF and run the engine until it comes up to nomal operating temperature then watch in the rad opening and rev the engine to check for bubbles nine times out of ten of there is bubbles, you have valve seat / wall cracks a typical overheated ford flat head issue
Stew
P.S while the engine is warming up also check the rad for bubbles, if they are
there before it gets warmed up it is probabley just the gaskets
