There is a small notch at the bottom of the water pump mount surface on the timing cover. Won't water leak from here? I assume that I am to make sure the Permatex fills this void.
I know this is where it leaks when the water pump "goes"
Is this notch serve a purpose? Should I just make sure it gets plugged?
The notch is there to serve as a drain in case the plate of the back of the water pump leaks. At least then you'll know there's a problem before it gets out of hand. Youll notice that many times there is a hole outboard of the seal on the front of the water pump snout as well.. serves the same purpose.
If you fail to install the gasket between the pump plate and timing cover, coolant will leak from this gap.
If there is a hole in the plate between the timing cover and the pump, coolant will come out this gap.
If the gasket is bad where the coolant passages (the 2 "D" shaped ports) are between the timing cover and the steel plate, coolant will come out this gap.
