i changed the thermostat as a precaution, the wierd thing is that it doesnt over heat.

i changed the original head gasket because of the pressure in the head and the rising water in the header tank.

i also changed the oil breather.

when the head was off i put a metal ruler along the bottom of the head and it wasnt warped. ive put a new felpro head gasket on and the sympom is still there!

the water rises in the header tank even when the lid is on tight??!!
