Yup, that is one "spanky" looking engine.

As for the toothbrush, I use Simple Green and thank God that power toothbrushes are so cheap these days. They are really good for getting into all the tight spots, although my engine looks nothing like yours. I was going to ask if you had a new one from a crate shipped in recently.
