I own a 2wd saph cosworth (stage 3). I have noticed a slight water leak under the exhaust outlet. There is no oil in the water and vice versa. Is this the head gasket gone?
If so what is the best replacement head gasket, were do I get it from. What else do I need to replace. Can anyone give me some instructions, i.e., which way the head bolts are undone and what else needs to be undone and how the head is removed. What is the order and torque setting for the new bolts? Value steam seals, should I replace them if so how are they done?

Many Thanks
