Also regarding your leak, if it's only an external leak & not into the oil then I'd personally risk seeing if a radiator sealant additive could resolve the problem - I know my radiator is weeping (leaving antifreeze trails) and I'm thinking this could be a reasonable fix - I can always flush it out later. Also, did you replace your antifreeze lately? My old BMW bikes used to weep quite badly after a change of antifreeze, but admittedly not from the head joint...

Mark,

Your car uses a heater valve to modulate hot coolant through the heater core. That valve has a very fine filter that would be instantly clogged if you use a metalic gummy sort of leak stopper. If your coolant leak is external of the block you might be ucky ennough to get fixed with a head bolt retorquing (sp??). R&R of the head gasket should be about 4 hours of labor + parts.
