Has anyone got any tips on washing the engine of my GT Forester. Is there
any thing I should cover/block for high pressure cleaning etc? Should the
engine be cold to start with?
TIA

In the olden days (days of my experience) you don't do it with a hot engine,
especially on an aluminun case. But by the time you wash your car the engine
should be cool enough. Other than that there shouldn't be any problems. But,
don't use a high pressure sprayer like they use to wash a house, you could
blow holes in hoses! Also, NEVER use the stuff that's used to clean really
cruddy undercarriage parts, it contains an alkali that can hurt aluminum
with extended usage.
Had a friend that used that stuff on the rudders of his English catamaran.
It had gotten really cruddy sailing through an oil slick. The English
aluminum had a high copper content and the stuff ate the copper from
the rudder. He had to buy new rudders as a result.
