LOSING COOLANT. NO VISIBLE LEAKS.

2001 Buick Century • 100,000 miles

I have a 2001 Buick Century that is always running out of coolant. It never comes out from under the car and we feel it is going in to the engine and has been in the oil tank. We have had it to mechanics many times and they can't find anything. They have replaced many things but it's still doing it. The car never steams and overheats but the heat gauge starts going way over when the coolant is low. Maybe you can give me some ideas about what to do. Could it be the radiator? The mechanics here didn't think so. I would appreciate any help you can give me.

If oli looks normal then the 3.1L V6 very prone for intake gasket to leak. With light look under intake area at rear of engine under thermostat housing see coolant. If yes then intake leaking
