If it's the former, shyt happens. Live and learn, happens to all of us at some point.

If it's the latter, a jug of Bar's Stop Leak works wonders. If you really need a miracle, CRC Copper Weld is divination in a bottle.

I've read some reviews that the stop leak type of products out there can also do a lot of harm, so I'm skeptical of using it. That said, I know my wife did get it pretty damn hot over the summer before I got the thermostat. Don't know if it got hot enough to do damage, but I'm not ruling that out by any means.

May put some dye in it and see if that can help me figure out of it's going anywhere. It has ~ $100k miles on it and this thing is gonna be driven until the wheels fall off of it hopefully w/out having to replace an engine or tranny.
