I assume I should not spray water at the engine compartment lid from the rear, to avoid getting water in there, correct? Or does it not matter?

Thanks.

Does not matter. Believe it or not our cars are all-weather cars. Do you live some place where it never rains? What happens if you go to work and your car is out in the rain? What I do is hand wash the car, hit it with the blower, lift the engine lid and blow the crap out of the engine bay. Cleans up nice that way.

Very little water gets in and the airbox is tight. Obviously don't stand there with a firehose and flood it...

Shouldn't matter, you could stick a towel in the opening if you are worried about it and most electrical connectors have gaskets and weather proofing. That being said I wouldn't get the strongest jet on a power washer and get a few inches from everything with the spray. When I did mine I sprayed it down with degreaser, let it dwell and then rinsed off keeping the power washer back a few feet. Then I blew it out with a leaf blower, could use compressed air or sometimes shop vacs have a blowing setting.

I think the manual actually says something like go ahead and wash it but avoid the alternator. So I would probably wrap the alternator with aluminum foil and blast away.

You drive the car on a long weekend drive. As your having lunch with your mistress at the sleazy motel, you notice it's starting to pour down raining. Your phone rings... it's your wife! You start to panic, skip desert, and jump in the car. Nothing worse than a wet Porsche.

Moral of this story - Check the weather before you drive your Porsche to a sleazy motel.

I thought the moral was condoms... I clearly need to start making Porsche specific engine washing condoms. It’s the perfect solution to a perceived problem.

There is a nice write up, I believe in the "Like father, like son" thread. Can look it up when I get home...

Better yet, put the aluminum foil on your head while washing the car...

Side spatulas generally help "straighten the water" - this can dovetail well with the foil technique mentioned above.

Wait, so Porsche no longer recommends an engine rebuild after every wash?!





When I replaced my motor mounts I tidied things up with some spot degreaser while the airbox was out. I rinsed with a garden sprayer and other than sticking a latex glove over the throttle body, there wasn't anything in there that I worried about getting wet.

Nothing to worry about if you are talking about regular garden hose spraying water with the engine lid closed. With the engine lid open, the engine and all the parts (except the alternator) are water proof.

Just a couple thoughts,,
I use a product on my KTM Street bike that's form Honda,, I think its called Honda wash,, there is a companion product called Honda shine,, but the wash gets clay, oil, and road slime off all the Aluminum engine parts very well. its a 'spray/soak/rinse/repeat' product, doesn't seem to hurt rubber or plastics.

There are also some products that are from teh dirt track racing market that are designed ot act like "pam" for your engine, you clean it and spray it down and nothing likes to stick, comes by the name of "dirt off" Mud buster etc,, seems like it would work well to help reduce cleaning efforts.

Cheers.
