I replace the uper and lower intake gaskets because the lower intake gasket was leaking small amounts of coolant into the cylinders and the water passages were leaking outward from the rear and front of the head where the intake mounts. i replaced both the upper and lower intake gaskets using all proper procedures. but now i still have a small leak somewhere. i was wondering if my leak could be caused from the water pump. this is a 3.5 liter and the pump is belt driven. i assume that this pump is similar to the 2.7 liter and has a weap hole to keep coolant out of the oil and off other componants. the leak doesnt show under a standard coolant pressure test. but when you let the car run, it starts to slowly leak the leak gets worse as you jack the car up or lower it. what i need to know is if this weap hole feeds into the vally on the top of the block. if so would this explaine my problem.
