Question

Quizplus · Accepted Answer

Both OHC (Overhead Cam) and pushrod engine designs can have oil galleries in their cylinder heads. In OHC engines, these galleries are necessary for lubricating the camshafts and valvetrain components. In pushrod engines, oil galleries in the heads lubricate the rocker arms and sometimes the pushrods themselves.
