Since we're talking about do's and don'ts of engine cleaning, my experience tells me don't do it. Haha. But I know that doesnt help anyone. I detail at a dealership and we degrease and powerwash the engines, but if they don't run right after it's not my problem, it just goes back to the mechanics. And about half of them don't. Its always the older or high mileage ones. So I'm lead to believe that if you have good ignition parts-spark plug wires, etc. you'll be fine. Also my boss says always turn on the A/C if afterwords to dry the compressor. Otherwise it can rust inside overnite and ruin it. Dunno if its true, I just do what he says.
