Abstract
A finger-follower rocker arm type valve train has a finger-follower rocker arm with an upper surface that extends essentially unbroken from end to end with a central area surface for contact with an overhead cam, the central area surface being concave for lubricant retention purposes and having additional lubricant retaining pockets in the surface as reservoirs to maintain lubricant at the surface at all times regardless of the operability of inoperability of the engine camshaft.
