Oil on Cooling Fins

I've noticed over the past several weeks an oil residue gradually covering the front fins of the forward cylinder and behind the rear cylinder. Is this just blow by? Should I clean the fins periodically, maybe w/a toothbrush or something, or is it something worse?

Have you recently changed anything on/in the motor? Rocker covers, etc?

don't worry. if it is the rocker covers... it's not major and relatively easy to fix. post some good pictures before you wash the engine.
