Help Please: Coolant Leak
My 350 has a small coolant leak (about 1 tablespoon per 20 miles). It pools in the depression around the intake maniflod bolt (Edelbrock) nearest the heater hose fitting. The heater hose/fitting does not appear to be the source as I cannot detect any coolant by running my finger around the fitting and tightening the screw clamp around the hose didn't help. It's difficult to see the source of the leak because it's small and only seems to occur when the engine is run at higher speeds. I suspect the bolt itself  Or worse- a hairline crack in the manifold itself. Could anyone tell me how to isolate the cause and what the fix might be?
Thank you.
