Get Block off plates on it. I don't see it sucking up anything cause of the location, but you never know what can happen.

It shouldn't suck up water because it's so high up. But I don't think it will suck air anyways, it only pushed air out the cylinders right?

But if it is open and not connected to anything, you will have a vacuum leak.

That Tube is there to let Exhaust get to the EGR Valve, so it can put it back into the Engine.

Cold air intake? Re-grease it or check for cracks.

It very well could be dripping water in from the plug holes above the plastic wiper assembly area.

I say seal the back of the intake and wait on the rain.
