I would try a new cap first since it is probably not very expensive. I have a feeling however that you have a head gasket leak. This is an internal leak that allows combustion gases from the engine into the cooling system. I hope this is not the case, but if it is then when you change the cap to a new one you will notice no difference it will do the same thing. Let me know what happens. Ken Wilford John 3:16 |
