Abstract
A high compliance seal is applied between each cylinder block end wall and an intake manifold which acts as a cover for the lubricant containing space between the banks of a V-type engine. The seal is formed of a rubber-like resilient material with rows of small waffle-like recesses formed on each of the sealing sides between intersecting spaced longitudinal and lateral ribs. The longitudinal ribs on the upper side are laterally staggered with respect to those on the lower side to form, as viewed in transverse cross-section, a sinuous body configuration that straightens out and flattens so as to combine with deformation of the resilient material into the recesses to provide a high degree of resilient compliance without overstressing of the resilient material.
