In the past I have used a product called Kem weld with great results ,One was a Chev 52 pick up that dumped most of the water out the exhausted this completaty stoped the problem ,A more resent one were I had a call from a stranded student in a El chepo Jap car she was being qauted all sorts of numbers to do a head gasket ,we tipped the $20 bottle of product down the radiator hoses ,I passed her six monthes later and yelled out the window your still driving that thing ,Yes she replied . You run the motor till very hot with a cloth over the radiator (the crack opens up ) ,then lower the coolant leval and dump the product in the top hoses ,refit the hoses and restart let it come down to normial thempature ,they don't mention pressurising the systiom but they do say remove any spark plug on the cylinder that has a issue ,I agree with the others that its not a permanent fix But .Byron send me a PM and I will sent you a bottle NC ,Ted
