Any problems with using just a regular water hose/nozzle (no pressure washer or anything like that) to wash the loose dirt and mud from under the hood, the motor and around the engine compartment? What about getting the pad on the bottom side of the hood wet? Maybe take it off first?
I used to take my old truck to the car wash, cover the breather with a plastic bag and wash it like that with no problems. So I figure new vehicles should be sealed up even better nowadays and there should be even less of a chance for a simple wash-down to cause an issue. Besides, when its raining, you get plenty of water splashing around in there anyway (not to mention all the muddy water that washed all up the top of the motor this past weekend).
