engine washing procedure recommended by BMW

[shogun]

Bring the engine to operating temperature, and switch the engine Off.

Cover or shield any component--such as the ignition distributor, multi-connectors, etc.--in the area to be cleaned with plastic sheeting.

Apply engine degreaser or general engine cleaning solvent to the dirty area, allowing it to soak for at least five minutes.

Spray warm water on the area to be cleaned, flushing the solvent and the contaminants.

Do not aim the water spray directly at components. Do not use the water spray any longer than necessary. Do not wash the entire engine compartment when only one area requires degreasing, such as the front crankshaft radial seal, M20 oil filter replacement, etc.

Blow the cleaned area dry immediately with moderate-pressure compressed air.

Start the engine immediately and road test the vehicle to confirm satisfactory operation.

BMW says it will not honor warranty claims for components damaged by improper engine cleaning.

we have our worst drought in 100 years. Water can only be viewed in museums. Guess we'll have to warm up some beer and wash it down. The car that is. Hang on... what do we wash the beer away with?. That's it! Drink lotsa beer and #iss on it:D
