Hahaha! Not even close. I don't know what'* wrong with it.. but the seal between the hood and firewall doesn't do a very good job. It'* more apparent when the car is sitting, but if I pop the hood after driving around in the rain.. it'* still got water sitting on some plastic areas on the firewall. I have the same problem on the trunk.. I just need to go out there one day, and sit in the trunk, and under the hood while somebody pours water along the seals.

How about under the hood? I might be able to fit under there but something might get broken.

Harofreak: I knew somebody would say that, and I am sure that will happen to me. So i'm going to take a sandwich in with me, just in case .

CmptrNerd: Unless your engine looks like mine [99% of anything bolted on or around the block, removed], then it is too dangerous, and you will run a very large risk of breaking something. But I have just enough space to squeeze my feet in, in front of the engine, and behind the radiator. It'* a tight fit.. very tight fit, but it works . That also helped a great deal when removing the rear header.. damn that was a bitch!

Most all of the electronics under the hood are designed to resist water. If this was the case dont you think you would have a lot of dead cars after the first big rain storms?

I'd cover the coils and alternator at the bare minimum though.
Rain doesn't get under the hood like a pressure washer does. Use extreme caution.
I've pressure washed the engine bays in my vehicles multiples times with no issues. I like to use the engine degreaser at the quarter car wash.

I leave the engine running and spray on the degreaser then rinse it off with the hot water. I don't blast it (I keep the tip about 2.5' off the engine) and try to stay away from the exhaust manifold, alternator, and coils.

ya if you spray water onto a hot manifold you have the risk of warpage or cracking it

Err yeah. Don't clean the engine with it even warm. Do it at least 30 minutes after the last run. Start the car up immediatly after washing it, this way all the extra water will be burned off. You don't want a rusty engine, now do you .

Mine was cleaned with a mild setting on the power washer. The engine was cool, and there were no problems. It was a quick 2 minute job that got rid of most of the crud.

I've never had a problem with power washing the engine while it'* running and I've been doing it for years. If done sensibly, I don't see a problem with doing it.

This is kind of like the situation with Carb Cleaner versus Throttle Body Cleaner. Yes you can use Carb Cleaner, but there are certain things you cannot do/use it on, while using it. So we just recommend TB Cleaner, since it is safe no matter. This is the same thing here. Yes, you can do it with the engine running, however there are many things you cannot, and lots of precautions you must take. It is just easier to explain to say "Don't run your engine 30 minutes previous to doing this, leave engine off, then immediatly start engine up after rinsing." Does that make sense? I'm just trying to make it easier on everyone, and myself, in the explaination process. Not to mention it'* safer this way.
