Have you considered epoxying the parts together?

When you google it there are some YouTube videos that show how. When you do it please document it because I will follow your lead.

I have been trying for quite some time to get the copper cooling pipe installed without leaks. I even broke down and ordered a new one for $100 for a copper pipe about 15" long with 3 fittings on it; one from the raw water pump, a "T" fitting into the bottom of the exhaust manifold and then one into the bottom of the thermostat housing. I would like to redesign this rather lame arrangement by soldering copper fittings onto the exhaust manifold and thermostat housing and then use simple heat rated tubing on barbs w/ hose clamps; anything that would make a better, easier fit than the existing POS. In fact, I think this is how it was done on the MD6A and B engines. Any advice would be greatly appreciated, John Stacklyn Cal 31 #33 "Sol Survivor" Shell Point, FL
