Here are before and after pics of cleaning engine. you can just use some tire cleaner or i used purlpe power cleaner from advanced auto. i used a 2500 psi pressure washer. YES its ok!! 2500 to 2750 psi is ideal. Anything higher you start blasting through rubber hoses and chewing stuff up!!Just follow these steps!!
1.) Make sure motor is cool
2.) Wet it down just a lil with water
3.) Spray down with cleaner and let it set for a min or two
4.) Spray engine down good with pressure washer
5.) Start motor and let run with hood down while you wash the rest of your rig.
6.) Turn motor OFF!!
7.) open hood back up and take a damp towl and just wipe it down.
8.) DONE!!!
