Vented oil filler cap! Since most of us are good at changing the air and oil filters on our cars, it's a wonder that more of us don't also remember to change the rocker cover cap that includes a filter. Most motors do not have a separate breather on the rocker cover and are thus dependent on the breather with filter inside the cap. Routine replacement is the only answer!
