I am working on a friend's 1975 SL 450. It's in pretty good shape,
but the engine is really dirty. The guy who owns our local German
auto shop told me that pressure washing the engine would be a bad idea
because the engine has electronic fuel injection, and that I would
likely get water in the injectors and that they wouldn't work right
until I took them apart and dried them off inside.
Does anyone have expeience with the 4.5 liter gasoline V-8 from that
What would you recommend for cleaning 34 years of accumulated grease
and dirt from the engine?
I am thinking I could lay towels across the valve covers and over the
distributor and clean those areas manually with solvent and rags but
pressure wash the rest.
What do you think?
