My dart block 347 recently started blowing steam and coolant droplets from the rocker covers. Drained the oil and found at least a quart of coolant in the pan. It hasn't turned milky and the coolant is staying seperate from the oil. Doesn't appear to be head gasket related because I'm not seeing steam out the tailpipes after the motor warms up or pressurizing the cooling system (even under boost). No missing or noticable reduction in power either.

The only other places I can think of where it would leak into the pan is the gasket for the intake manifold to heads or between the timing cover and block. Which do you guys think is more likely and is there an easy way to test for where the leak is coming from ?

Im pretty sure that there are hose plug kits available. You plug the radiator hoses and heater hoses, if you have them and pressurize the cooling system. With nothing running and the coolant drained you should be able to pinpoint the leak. A stethiscope or ultrasonic refrigerant leak detector would probably be a big help.
