Hi Stevo,
I had a couple quick questions about this post from waaaay back in 2011...
Do you happen to remember which stop leak product you used? Did the leak return in the 8 years since then (probably)?
Did you just set up your bilge pump to circulate water into the heater core at the T-junction on the firewall, and grab the return (which I think is down below)?
Thanks,
Kurt
