My intake gasket blew but after there was a water pump leak and thermostat gasket went. The old gasket didn't fit the truck well at all; so I had a new one installed. Here's the problem. After the intake was installed it was still leaking very slowly. The dealership put a pressure test on it which showed nothing. Now the coolant is starting to draw down, but I'm not seeing the leaks. Is the truck burning coolant abnormally. The engine suffered NO damage when the water pump went nor was there any signs of overheating at all. It was caught somewhat early.
