while I'm in here? I don't have plans on going back into the engine anytime soon.

I have the valve covers off and the intake manifold out. The intake manifold is an oily mess and a pretty sizable piece of carbon (I think)in a circular shape about 1/2 inch thick fell out of the intake manifold when I set it CCV side down of the floor.

I plan on wiping down all of the oil everywhere and cleaning inside and outside of the intake tubes but is there anything else I should do now that I have the car all apart?

I'm guessing this is a terribly dumb question but can I put the intake manifold in hot soapy water to clean it? The injectors and fuel tube are still attached. I know water and gas don't mix but it can let it sit until all of the water evaporates.

Thanks,

I'd remove the nuts that hold the fuel rail in place and take it and the injectors off. The injectors will stay attached to the fuel rail if you leave the top clips in place. The bottom of the injectors are just stuck into the manifold with a o-ring to seal them. Pretty easy to remove the whole works, just pull up after you remove the nuts.
Dawn dishwashing liquid and hot water does a great job of cleaning oil and grease.
I saw your post above about the oil separater, you don't want to go there unless you were having problems that a ned CCV didn't fix. You will need to pull off the front timing chain cover to get at it.
Valley pan and t coolant pipes look OK?
You may want to just give the bolts that hold the VP down a slight turn to make sure all of them are tight enough, don't over do it.

It was a mess of oil, some antifreeze and gloppy material that sort of resembled very soft slate that held it's shape until I pressed a screwdriver into it to break it apart. It wasn't actually filled. The dirty stuff rose to the height of the black plastic valley pan cover but not on top of it.

What would I be looking at with respect to the tubes? They look metallic to me. I haven't been loosing too much if any coolant that I recall.

I can't wait to get my car back together and start driving it again. I've owned this car for over 8 years and I still miss driving it if I go beyond a few days without it.

Thanks,

To replace the VP you need to remove the two metal tubes first.
To do that you either have to remove the waterpump or to rear crossover between the back of the two heads.
I like to remove the waterpump, it's up front and easy to get at.
You should try to figure out where all of that crud came from.
