Some have used Simple Green and then a light stream of water to do the trick. I have never washed my engine - just wipe it down every now and then after I was the outside of the car.

I saw a post a while ago that said NASA stopped using a similar product to simple green because of a deterioation to aluminum parts on aircraft. I'd reasearch it a little further.

I would suggest just wiping it down with a rag with maybe simple green or another cleaner on it. and used compressed air to clean out the hard to reach areas. If you do use water, use a soft stream, don't go nuts and power wash it.

I vacuum my engine with my shop vac!
There is always a little dust and grit on top of my engine after a day of driving so I simply open the hood and vacuum off all exposed areas. It keeps the under hood area looking like new. I would never consider washing my Vette's engine. After vacuuming I wipe everything with a damp detailing towel. Of course this process only works if you start out with a clean engine, not one that 80,000 miles with no attention.
Products like Fantastic and Simple green are highly corrosive to alumnium and can discolor many items under your hood.

I cover the air intake filters. Spray the engine down with Simple Green and then wash with garen hose.
Carefull not to spray the intake plenum hard.
Then let the engine idle till it is dry.
I have been doing this for years.
I am curious about the simple green hurting the aluminum. My engine block looks fine.

I have always washed my engines....from my old mini truck , street rod and motorcycles. I spray simple green on a cold motor, and rinse with the pressure hose, use low pressure around important stuff. I have NEVER had a water related issue from wahing a motor. Most motors are fairly water proof. Washing helps you find oil seep sooner, keep dirt from building up and holding in heat. I use a turkey baster with a small hose attached to suck up the pooled water on the intake and in nook and crannies to keep it form crusting up..works great. I have never had a corrosion problem from washing , I make sure they are dry and spray SP100 corroson inhibitor on the engines twice a year. The motor is the heart, keep it clean.....inside and out

WOAH..... Well, I'd NEVER spray water all over my engine bay.. that's for dern sure. Now.. I do hand wash the components and vaccum out dust and such. I had an IDIOT spray my C4 engine bay down once and it screwed that car over and it was never right again. (Yes yes.. I know.. probably just the optispark..). I just can't see all the electrical components digging having water squirted on them.

I've used a diluted mixture of simple green for years. I just spray everything off with water very well and then take the leaf blower to blow the heavy water off and start and let it idle and run until dry. Never had a problem and my engines look brand new. To each his own.

I use my air compressor to blow out grit and such, then I use a damp
cloth and wipe everything down that I can get to. I don't use the
compressor everytime but I do wipe the engine down everytime I wash.

40psi air does the trick every time 
Honesly I have a compressor/tank from sears so I can set tire pressures and use air tools at home. I bought a little quick-release accessory kit, one piece of which is just a little trigger/air gun.
Set to 40psi and blow away
It works very well unless you got something wet, such as in rain and then I just hand-wipe as good as possible.
The air stream is PERFECT for cleaning out the runners and indentations in the intake and around the injectors and coil packs. It's also great for the radiator area ... heck it just works great!

I used plain water to rinse my engine yesterday. I had sand and salt water built up from my 4 rainy days at Myrtle Beach last week. I drove through standing water down there from Hurricane Bonnie, then got even more from Charlie right after. When I saw all the sand that had collected in the engine compartment, plus knowing the salt from the rain and the beach that built up, I HAD to spray it down. Gentle pressure for the most part, then wiped dry. No problems.
