The oil and coolant aren't mixing, but water pours right out of the side of the block. Can't really get a good look at it since it's on the intake side of the engine. I pressure tested the cooling system, and like I said, just pours right out. Seems to be along the whole side of the engine. Could it have just blown out the water jacket part of the gasket, or could it possible be a freeze plug or two? It does just fine on the interstate, until of course you hit traffic and have to slow down.

have you checked your compression?
if its really low, you should machine or replace the head and the gasket
