This is the process I use when washing and degreasing an engine before returning the vehicle to the customer after major engine work was preformed. This is not a proper method of engine washing and should not be followed as a guide. Pressure washing an engine is dangerous and should not be done unless you are willing and have the ability to fix and problem generated in the process. Ther

    Distributor cap was 1 thing I had a problem with .Back in the day used a plastic bag to cover it no more problem wasn't hard to dry the inside of cap. Don't have that problem these days I don't see any problem with washing engine bay

    I've been told by every mechanic I've ever known to NEVER spray water under pressure under the hood.

    I have been DIY wrench turning since the early 1960s and I have always sought to keep the engine, transmission, differential and all the undercarriage clean as possible. I appreciate a clean car when you have to work on it and a clean car is easier to monitor for fluid leaks and broken parts. Back in the early days all you had to worry about was condensation in the distributor cap, these days it is a mine field under the hood and your comment "should you wash it" was accurate. A pressure washer is a dangerous weapon of mass destruction in the hands of the average motorist, they just do not know how to move that wand around to get a good cleaning job without damaging sensitive electronics. I always use a leaf blower right after washing and blow everything bone dry before starting. And I wash on average no more than once a year. Too many washings can lead to corrosion build up in connectors so limit the exposure to the water is the rule. Under the hood is engineered and designed to withstand a harsh environment including temperature extremes, water coolants and various petroleum fluids but not to tolerate ultra high pressure force of these materials where they do not belong. Negative comments don't have the facts behind them, they are passionately defending only their misinformed opinions.

    I keep my engine reasonably clean so when the mech works on it he doesnt have to get all dirty and greasy when he works on it.
