Can someone explain the valley pan?
And am I correct in that there should not be any coolant in the bowl under the plastic cover? I just removed mine and there was coolant in it, how does it get there?

If it were just a plate the engine would take a lot more coolant to fill, wouldn't heat the coolant as effectively and the flow characteristics would suffer in that area. The plastic cover is really just to keep dirt out I guess... And no, there isn't supposed to be coolant in the bowl, it must be leaking. Hopefully you are changing it!

When I decided to do the valve covers i figured why stop there, and Im glad I did, just about every rubber hose I touched fell apart! Weasel I have a question for you, you seem to be the resident expert and maybe even a tech so... When replacing the upper timing cover gaskets the TIS says to use a special tool that goes into the valve cover gasket grove, then you torque the valve cover down to press the timing chain cover down flush with the head, then you tighten the timing cover bolts, so the actual question is, is this really necessary? is there something that can be used in it's place?

What the tool does as you can guess is press the timing cover down to have proper tension on the bottom part of it's gasket, otherwise it will leak. As long as you can find a way to compress the timing cover to the same height as the head surface when you tighten it you will be fine without the special tool. I am soon to do this same job on mine as the timing covers are leaking now, and I only want to go in there once.

Do you have that tool? If so can you tell me the material it's made from and the thickness of it installed? I want to try to fab something up, I cant even find where to buy one...

It is a BMW special tool, in the "special tool room" at work. (dealer tech) It is steel and maybe just over 1/8" thick (probably metric measurement thickness knowing the Germans) maybe just some flat bar from home depot could work.
