Well, I haven't got any new news from the engine machinist, so I got anxious and cleaned the engine compartment with Simple green and a tooth brush. I feel better now. And I'm starting to worry I have slight obsessive compulsive disorder......Oh, well, why not apply it, right? Heres my comparo photo. Simple Green is awesome. I think they should sell it as a deodorant scent, and wd-40 as aftershave.
