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). A respective cover (10) is associated with each respective cylinder assembly (30) of the engine (20). The walls of the cover (10) block flow of oil onto the joints of the multi-cylinder cover assembly (42, 60) to minimize leakage.
