I just can't see how cooling system pressures can overcome combustion chamber pressures.
Now, for those leaks where coolant is actually making it out the exhaust - obviously there is a portion of the cycle that is allowing coolant to flow into the CC. But that is rarely the case for 'typical' soob HG failures where you get bubbling in the radiator/overflow tank.
I'm sure K-seal probably works fine for many external leaks - as would the re-branded Holts Rad Weld sold as Subaru Conditioner.
