What goes in this hole?
While changing my plugs and wires this weekend, I noticed this hole in the inlet manifold. Should there be a bolt in there? If so, anybody know the length/size?
It's clear somebody with "questionable attention to detail" has poked around the engine compartment before, so I get nervous when I see things like this.

I haven't had things far enough apart to know what is directly under it. Anything on the other side to worry about?

It's a drain hole for water (not coolant, think water crossings). It doesn't go inside the intake, that's just a support webbing. You can plug it or not, doesn't really matter unless you get water in there. (then it still probably doesn't matter, the heat these engines put out would evaporate any trapped water in short order)

Of the three Bosch engines I own, one has this hole. There is a plate type gasket below, sealing the upper and lower manifolds. Water flowing in from a wash will drain to the gasket, then out the back if there is sufficient space, without harm. I'm only guessing, but I think the hole may have been used in some way to suspend the gasket during assembly, with the fastener removed once the upper manifold was in place.
