I just cleaned mine the other day and used Gunk Engine Brite. Sorry, no pics, but jschmid's engine is pretty representative of how mine turned out. Check out this link from the DIY forum. Pretty good discussion about cleaning the engine. https://www.honda-acura.net/forums/s...t=clean+engine .

There is one tip in there about using tire foam and/or silicone afterwards, but I chose not to use anything as they tend to attract dirt. My engine had 60k miles worth of grime, and it turned out great.
