ABSTRACT:
In an internal combustion engine a breather induced valve lifter mechanism lubricating system wherein oil mist is conducted from the crankcase through one push rod tube to the rocker box. The oil mist is caused to flow around the valve actuating mechanism by a baffle before flowing out of the rocker box through a second push rod tube to the breather chamber. Oil which condenses in the rocker box flows through the second push rod tube to the breather chamber. Oil which collects in the breather chamber will be caused to flow through a drainage passage from the breather chamber to the oil sump in the crankcase.
