Abstract
A plurality of positioning grommets are fixed to a gasket for use in an internal combustion engine. The gasket is adapted to provide sealing between two separate but communicating engine parts which contain mating bores for passage of mechanical fasteners. One of the parts includes at least two counterbores, each concentrically aligned with one mechanical fastener bore. Each counterbore is adapted to receive a grommet sized and toleranced to assure clearance from the sidewall and bottom of the counterbore, and hence to provide an interference-free grommet-counterbore mating. In a preferred form, each grommet body contains a plurality of circumferentially spaced integral detents.
