I tried a search and didn't exactly find what I was looking for, so here goes:

I have coolant collecting above the engine mount on the passenger side. I tool off the passenger side wheel and splash cover, and it appears to be coming down by the oil filter housing.

Using a mirror I looked thoroughly around the water pump, and everything appears to be dry.

What I do see, looking between the water pump and power steering pump, is coolant near the block itself. Does the water pump housing have a gasket at the block that is prone to leaking? Is this actually coming from somewhere else and I just can't see it?

When the lower intake manifold gasket leaks, where is it likely to show?

thanks for all help.
