I don't know if I'm a idiot, brave or lucky I've cleaned at least 500 engines with a pressure washer and never had a problem that includes classic corvettes & camaro's hot rod T buckets, and late model cars and trucks have any of you actually had a problem that amounted to anything more than a wet distributer?
also sorry for being off subject
With european cars, the later they are, the more delicate they are.
Although we have interceptors at our static operation, we still don't put water anywhere near engines these days. It's too risky. We also have had problems with electrics situated behind the dashboard, under seats, under the floor pans, and electical connectors situatated in the door shuts.
If I didn't know better (which I don't come to think of it) I'd say that some german cars are actually designed to channel water towards the electics and CPUs.
The situation cost us so much money through late 2004 to mid 2005 (mostly through lost work time rather than replacement parts, although had we payed full price for parts it would have cost something like £8000), that in the end we called in a mechanic and an auto electrician to advise us, as a result we now only clean engines by hand.
For the vast majority of people, there is no real reason to clean the engine bay, the only person who ever sees it is the mechanic who does their service! So instead we concentrate on protection, there is a lot of bare unprotected metal under most hoods.
