[A4] Engine Cleaning Products

[Richard Hurt]

I recently had my timing belt replaced along with my front crank &
camshaft seals and would like to know what everyone uses to remove 2
years of built-up oil and muck.  The seal replacement should stop the
leak (hopefully) but I am still getting burned oil smell after a long,
hot drive.  I am planning on taking the belly pan down this weekend
and giving everything a good cleaning but would like to get some
recommendations for this task.

I have used Engine Brite foam and Simple Green spray in the past but
neither one really impressed me that much.  Engine Brite is pretty
expensive if I remember correctly and didn't seem to leave a shinny
gleaming surface.  I really like Simple Green for a lot of jobs but
it's kind of hard to apply to the bottom of an engine.  :/

What else is out there?  Obviously, I don't want to sit under the
engine all day with a scrub brush and have soapy water drip in my
face, so I am looking for something quick and easy.  :)

Later...
