A word of warning....

Using pressure water in the engine compartment can get water in the
spark plug holes and cause massive miss....

I think I saw on Discovery Channel Mythbusters that Coke was an excellent
engine cleaner.
I also think Hachiroki must have been very lucky, more than me.
I do not recommend having the engine running, I think you should wait till
the engine is cool so you don't risk a cracked exhaust manifold.etc. from
the water spray on the hottest parts.
And I have learned to avoid spraying water into (on) alternator,
distributor, air intake, headlamps and brake fluid reservoir. Be especially
careful with high pressure spraying, it can force water past seals and may
damage (old) rubber parts.
Start the engine soon afterwards so it dries up.

I don't use the pressure washer but usually hose off after spaying
with some type of cleaner. Only problem was years ago with old
wires - not any for 20 years but watch alternator etc.

I use Simple Green on a cold engine with a small brush (tooth brush)
one section at a time, being very careful to avoid areas that should
not receive water.
Then rinse with a garden hose turned on just about as low as possible.
Having replaced all the necessary gaskets and seals, engine now stays
very clean.

Perhaps you might want to lift the hood on your vehicle and look at how wet
everything is under there after you have driven in a hard rain or snow
storm, if that is what you believe.
