Hi:

I'm with Ben on the don't fool around with "cures in a can" EXCEPT
that Stop Leak did exactly that (stopped the leak) with a MINOR
coolant leak on my 1.9 for about 2 years before I pulled it in favour
of a Bostig Zetec. Having said that I would certainly want a several
hundred mile test and in the hottest of conditions before I set of on
any journey, particularly with my family. The best place to fix
something is at home, not on the road with unknowns everywhere.

There are good used economical engines out there and the head reseal
alternative is not all that bad either. One thing for sure, you will
know a hell of a lot more about your machine if you change engines or
repair your engine than if you pour a can of additive into the
cooling system.

Good luck and let us know how it shakes out.

Ian
