Stop Leak Additives

[mbboy]

I know that many people here frown on using additives to stop coolant leaks. But I have a slow coolant leak from a recently replaced head gasket or intake manifold gasket, and I don't have the time or ambition to start tearing the engine apart again. So I was thinking of seeing whether a leak stopper might do the trick.

After searching, some people swear by Bars Leaks, some by Wynn's, and others by some other brand. So I was wondering if anyone here has had any good or bad experiences with these.

The potential problem seems to be plugging the heater core and/or radiator. So I was thinking I could use a valve to close the heater core off. and since I have an extra radiator, I could put that in temporarily, and replace it after flushing the system.

I know it's not the ideal solution, but some people out there seem to have gotten really good, long term results plugging head gasket and other leaks with some of these products.

Advice on using these products would be appreciated
