Good morning everyone. Over the past year I resurrected an old 674 gas. It sat outside for a few years and became locked up. I carefully pried the flywheel back and forth
until it was unstuck. 3 of the 4 cylinders had stuck valves. No big deal, I got everything free and adjusted correctly. I recently used it and when the thermostat opened
it starting pouring anti freeze out of exhaust port #1(i believe, closest to the radiator). Tore the head off, the gasket didn't look bad and both surfaces didn't look
that bad at all. Before I tear into the block, does anyone have any other ideas why this could be happening? I pondered water pump gaskets, but I don't know if that would
cause it. Any input would be greatly appreciated. Thank you.
