I use these products on rebuild, the Holts fire gum for turbo to exhaust manifold and turbo elbow to exhaust down pipe. The loctite 5926 is fuel, oil and water resistance at high temperature I've used this in the absence of the odd missing gasket for years, highly recommended products. I also use the Loctite 5926 as a replacement for Part No 08826-00080 packing seal. If you need to use old fuel line washers and they are made of copper, heat them up (red hot) immediately quench them in water to anneal them. Aluminium is annealed by heating to 550? C and air cool. Couple of quick questions; have you replaced the oil seals on the front cam journals and oil seals for the valves.
