no idea dude...don't pressure wash your engine, unless you're doing a rebuild in your driveway and are taking the whole thing apart...
a damp rag + a drying rag and a little hands on wiping will do the job everytime. you can be as delicate and as rough as you need to be by hand to clean an engine bay.
