Couldn't we have a sticky in every forum stating not to wash your engine because it will almost definitely cause you problems if you do?
This is quite a bold statement. It is
*very* arguable whether you will have problems washing the engine or not. If it was so inherently dangerous to the engine bay the manufacturers of spray on engine degreasing solvents wouldn't be selling those products because they're liable if you f*ck up your engine.
Now I wouldn't take a pressure washer to my engine bay because it's not necessary to use that much force, if you use a solvent you just need to rinse it away not force water into all the nooks and crannies.
FWIW I've washed the engines in 4 of the 5 cars in my driveway using gumout steam premium and/or gunk foamy (prefer the steam premium cuz it smells so good) with *no* ill effects. Well, to be honest the SHO's fan controller kept the fan running until it dried out, about a half hour. That was because I went in there a second time a lot more aggressively than the first "pre-cleaning" time. In addition to these cars I've used can steam cleaner and the garden hose on 2 toyota camry's. Camry #1 could take all the water I could dish out, without covering anything up, because everything is
sealed from the elements by design, and toyota's is a good one. The second camry was not a california car and I suspect this might have something to do with not all of the electrical seals being factory tight and water proof. It would do the same thing as it would do after driving through a huge puddle, run rough until dry (a couple of minutes).
Now I'm not recommeding that everybody go out there with a can of solvent and a garden hose and clean their engine bay. If you do you definately have to look out for water getting into the spark plug tubes (seal the edges with silly putty maybe?) I just think it's getting a bit carried away to instantly condemn everybody who does it.
