I know this is an oooooold thread.. but you guys who have trucks and like to go mudding or have to drag your Blaster through some to get to a nice spot to ride, you can also do this to your automotive engines. Just soak the whole engine bay (with the exception of the distributor) in WD-40 while cool, drive it to the car wash to heat it up, and use the high-pressure sprayer on it.
