put some more simple green on the engine, let it sit, and spray off with a hose. Then go over some of the hard to get at or harder to clean places with a quick spray of simple green, let it set, and wipe off with a cloth.
The tail lights really dont look that bad for some reason, and im loving the headlights, i kinda have the same thing going on.
Paint the valve cover, and soon...
