Steam Cleaning An Engine?

I've read that washing your engine is unnecessary, and has to potential to introduce electrical problems and/or corrosion (or was it electrical problems due to corrosion?). But I am not an expert.

here's a good video

Keep the engine running while cleaning as the water could get into the distributor cap and short the engine then you will have to take to a mechanic shop to wipe clean the distributor cap as it will not not start. If you work on your car under the hood it would help to keep it clean as the grease and dirt will mess up your hands and clothes.

In the Army, way back in the '60s we used to steam-clean the engines on our trucks and jeeps on a regular basis. Didn't cause any electrical probs that I can recall.

Military grade are rugged. They were built for battle so a little moisture mean nuthin. Some cheaper cars don't start after pressure washing especially those with larger tolerances.

Yes it great idea , in my street also using this idea from last years .
