Craig (solo_mata_me) showed me an excellent way to clean/detail the engine. Use the Gunk foamy brite engine cleaner as directed on can. Then use some foamy tire brite (I think it was silicone based by Black Magic). Spray that all over and drive the car around. After about 30-60mins, pop the hood and wipe off the excess. Looks absolutely beautiful...and no having to get your hands dirty.
