This really sucks.
If Nate says that He changed the head gaskets I would believe Him.

I have never heard of this product but have a very high opinion of BG Products oils.

"i would try BG Coolant System Sealer. i have seen it seal some extremely bad head gaskets before. if the head is cracked it won't work but if it's the gasket it will seal it right up. "

Back in about 1977 or so I was told to add some block sealer into a small block Chevy with a HUGE water leak, somewhere on the engine.
Whatever the product was it absolutely worked.
I would love to have some today, but time is fleeting, memory fades.
