I know there have been many topics on this but working for an auto detailing company i wanted to give some advice and show a pic or two
first this is our way, degrease the whole engine, starting as low down as possible working ur way to the top. begin with the fender side, then stand in the front and end on the passanger side fender.
scrub with long handle brush and rinse, we use high pressure hose(pressure washer), cover with tire sill ( tire shine)
now having said that, i cover my intake, alt, alarm, any wires...ect
for this purpose i didnt cover anything (as its not required) over soaked everything and the car started just fine.
i use simple green at home, ours is much stronger and it does get on the paint (mainly fenders but as they are already wet and rinsed off within a few mins i have had no problem with messing up the paint job.
pics are of a V6 with 67K miles

after, the yellow you see in the pic on both far ends are form the flash
