Engine clean?
 

Spring is coming and I'm going to wash the grime off of the engine and under the hood on my 4.4. After 6 years of operation it's looking a little gritty. On past cars, I would spray it generously with Simple Green and hose it off. Has anyone done this and have any comments or suggestions I should consider?

Unless you know what your doing i would seriously consider having this done professionally. Thats all you need is to get water where it doesn't belong.
