ABSTRACT OF THE DISCLOSURE A water-cooler engine exhaust manifold has an internal exhaust conduit or heat sheild comprised of a plurality of axially shiftable sections through which the hot exhaust gases pass from the engine to a hot gas turbo- charger. A casing encircles the exhaust conduit and is held in spaced relationship to the exhaust conduit so as to provide dead air space or other insulating material space for insulating the hot exhaust gases from the casing. An outer shell encircles the casing and is sealed to exhaust inlet elbows and to fluid inlet flanges to provide a water jacket to cool the surface of the casing. The exhaust in- let elbows communicate with each different section of the exhaust conduit. Clearance is provided between the ends of each section of the exhaust conduit to permit expansion and axial shifting of the sections of the exhaust conduit without, in any way, interfering with the function and operation of the fluid-cooled jacket of the manifold. A novel method for assembling the sections of the exhaust conduit and the other parts of the manifold is provided. - 1 -
