Washing under the hood?

I have a 96 F-250 7.3L PS and I would like to clean the engine and everything else under the hood. I use to do this with my older vehicles but with the newer electronics and such, I've heard some horror stories where it wound up costing some folks a lot of money because something went out due to water damage. Needless to say, I haven't washed an engine in many years but I'm thinking there's less to worry about on the diesel motor. I'm wondering if this is as much a concern with my truck as I've heard with others. If anybody has washed their engine, I was wondering what I would need to be carefull of and/or wrap in plastic. Some of the carwashes around here have the engine degreaser setting so that's most likely what I'll use for soap. Any sugggestions or feedback will be greatly appreciated.

Thanks!

I have done mine a couple times, I just use walmart bags and cover the alt, and fuse area. I wouldn't use a high pressure system like at the car wash area though, but thats just me. I mostly use engine degreaser and scrubbing bubbles with the hose.

i washed mine yesterday, i have done it more than a couple time i just pull of the top plastic motor cover and go at it. i use my pressure washer and do everything the top sides bottom and it comes out really clean. i had a small diesel leak at the fuel filter i didnt notice till i cleaned it. but pressure washer dose it perfect with out soap or chemicals. If worst comes to worst and you some how get an electrical connection wet just spray some wd40 in it and it draws out the moisture.....Hope this helps

The main reason I want to wash it is because I can smell some diesel at certain times and I think it should be easier to find the leak once it's clean.

Thanks for everyone's replies!

i wouldnt worry too much, avoid the air filter if you have an open element and make sure the drain hole in the back of the engine valley isnt plugged with gunk before you spray
