ABSTRACT:
An apparatus for fixedly securing a cylinder head cover to the cylinder head of an engine having a bolt embedded in and projecting outwardly of the engine so as to protrude through a hole in the cover. A cap nut is engaged with the outer end of the bolt for pressing the cover against the cylinder head. A seal packing and a washer are disposed in surrounding relationship to the bolt and confined between the cover and the cap nut. The seal packing includes an annular lip portion which projects axially of the seal packing and passes through a hole in the washer, which annular lip portion is disposed in snug sealing engagement with an end wall of the cap nut in surrounding relationship to the bolt. The washer preferably cooperates with at least two such bolts to prevent rotation of the washer.
