ABSTRACT:
Methods for forming heat-insulative gasket structures permitting the selective variance of components thereof whereby high torque retention, heat-insulative and fluid-tight sealing characteristics are obtained in an internal combustion engine between the intake manifold and the carburetor throttle body or between the carburetor throttle body and bowl. The method provides for densified and non-compressible bolt hole portions to be achieved by mechanical compression, provision for suitable insert members, or a combination of the two. Such portions provide desirable characteristics to control spring action and torque retention of the structures. The method also provides for formation of fluid-tight compressible sealing beads from the gasket material on one or both sides of the insulator member.
