Being an old fart with little else to do, I take a different approach to the whole engine bay thing:
Step one: Do something to engine; do it wrong.
Step two: Forced to remove engine due to step one, leaving engine bay open enough to climb inside of.
Step three: Sit inside engine bay area with lotsa rags and a couple of toothbrushes.. compressed air nozzle and strong vacuum cleaner helps with this step.
Step four: Choose otherworldly color scheme from PepBoys rattlecan selection, get storng buzz, and empty cans of paint onto engine and associated parts.
Step five: Assemble the wretched mess again, and hope PepBoys still carries same spray paint colors by next time engine goes "kablamo".
Step six: Take digital pictures of results, upload to photobucket, and post so many times that people no longer remember your screen name but can identify your bay from a lineup of usual suspects.
TaDa!
