Do NOT EVER use stop leak or any other coolant leak sealer in any automobile engine. Ever. Go ahead and use it in old tractor engines or other equipment, but NEVER in an automobile.

Nope, you guys with the stop leak solution apparently have never had to deal with the consequences of using that stuff.
