| a leak like this is easy to repair if you keep the right perspective. first you need to find the end of the crack and use a special screw that you can buy to stop the crack. you but them at any GOOD auto parts store, not kragens or schucks. you drill a hole and the special screw goes in to lock the end of the crack. after i do that i cut a mild groove along the crack and then braze it. use the torch to keep the metal warm as it cools so it does not cool too fast. use a grinder to dress the brass to match the surounding area. after it is cooled use a tap to chase the threads for the fitting. after all of this is done, repaint and use it. the perspective i like to give on a repair like this is the fact that the manifold will never get over about 300 degrees no matter what, brass sticks well and doesn't melt at that temp, and it is only subject to 20 pounds of pressure maximum. if a brass radiator can hold together with just solder then a brazed crack in an intake water passage will last until the earth has cooled to ice. hawkrod |
