I'd really like to get my engine and engine compartment looking better. It seams that some engines/engine components are more tolerant of water than others. I was thinking of stema cleaning the engine. Is this a good idea to do w/ my 1980 450 sl,or bad, or are there jsut some precautions that I need to take?

Thanks for the advice,
