I'm going through about 3 gal of coolant each week. No
visual leaks under engine. I have a slow drip of water coming out of both exhaust pipes (true dual exhaust). Based on reading forums, it might be the poorly engineered intake manifold gaskets. Truck runs great...no rough idle. No water contamination in oil. My first impression was head gasket, but lot's of intake gasket feeds. Didn't do pressurization tests, but that would still point to the two possibilities in question. I'd hate to replace the intake gaskets and find out it was the head gasket. Anybody have some insight on this?

Try pulling the spark plugs to see what they look like. It may be leaking into the cylinder(s).
