Hi I own a 2wd Saph (stage 3). There has been a constant drip from between the thermostat housing and the head. After removing the thermostat housing I noticed considerable pitting and wear of the head. I have tried a new gasket and hylomar blue but it still leaks. Can this be repaired without taking the head off? If so what can I try?

Many thanks.

 

Interesting question. I have exactly same pb. But no solution.

Regards.
