Abstract: A cover (10) is for use on a multi-cylinder overhead camshaft engine (20) having a pair of projecting members (112, 120). The cover (10) has a plurality of walls (300-308) for intercepting oil sprayed from the camshaft (80) of the engine. A pair of tubular projections (328, 330) connected with one wall (300) of the cover are engageable in a press fit relationship with the projecting members to support the cover in a position adjacent to the camshaft. A plurality of ribs (310-324) are disposed generally above the camshaft and extend parallel to the camshaft for catching and collecting oil sprayed from the camshaft and for dripping the oil down onto the camshaft. A W-shaped rib (326) on the inside of the cover collects oil flowing along the inside of the cover. The oil drips down from points (476, 486) of the W-shaped rib to lubricate selected portions (180, 206) of the engine. A multi-cylinder cover assembly (42, 60) encloses a plurality of the covers (10).
