ABSTRACT:
An outer cover member of a plastic rocker cover has a top wall, a peripheral wall and a partition wall cooperating with the top wall and the peripheral wall to define therebetween an oil-gas separating chamber. The peripheral wall has a plurality of flanged portions at which the rocker cover is to be bolted to a cylinder head. The outer cover member further has a plurality of resiliently deformable buffer walls integral with a top wall of the outer cover member and depending therefrom so as to be spaced inward from the flanged peripheral wall portions. The partition member is secured to lower ends of the buffer walls so that oil-gas separating chamber is partly defined by the buffer walls. The buffer walls are resiliently deformable to absorb thermal expansion and contraction of the partition member.
