I've seen some people painted their motors and others have only painted parts of their motors. I was wondering what everyones thought was on whether it is ok to do so. I'm referring not to peoples personal preference on how it looks but more so on whether it is bad for the engine heating up too much? I'm wondering about three engine parts in particular, and NOT the crank case at all. The 3 parts i was curious about are the CYLINDER HEAD COVER, the CYLINDER HEAD, and also the CYLINDER BLOCK. I wanted to paint the cylinder head cover with a wrinkle black, and then the cylinder head and cylinder block with a light coat of black engine paint and then sand/polish it off the ends of the fins.
