Cleaning the Engine Bay

Well as the title states, I'm getting ready to clean the engine bay on my early 99 7.3. I received some of the plenum inserts and plenum boots from riffraff for Christmas, and figured while I was in there to give the engine a good cleaning. I know with the intake manifold removed, it'd be a lot easier to clean the valley (which has quite a bit of fuel in it since my drain valve decided to spring a rather sizable leak). However, I wouldn't want to get any water in the intake plenums. My plan is to wipe/ vacuum any excess junk, then hit the valley with a lot of simple green, then scrub, then GENTLY hose it down with water. As long as I'm careful, I should be able to do this with the intake manifold removed right? I plan to cover the intake plenums up well with towels. Or would I be better off leaving the intake manifold on and cleaning everything? Thanks for any tips/advice!

I'd leave the intake on to clean it first. Spray the simple green, let it sit a minute then hose it off. After you get it mostly clean then take it apart do your work and clean it by hand if it's not good enough. That's my two cents.

Put some latex gloves on the intake plenums and go crazy.

Cover the power steering pump cap too, just in case you get a little ambitious.

Simple Green is very corrosive to aluminum so be careful what it gets on. They had to make one specifically for airplanes that wasent so corrosive.

Might want to get a specific engine cleaner.
