Okay,
I'm looking for some ideas.... I have a 1971 1.7 - stock heat exchangers, manta exhaust. I've replaced the copper gaskets between the heat exchanger and the head, applied what I think is way too much torque to the exhaust nuts and can't get it to stop leaking. I removed the exchanger and made sure the top of the flange is level and smooth. When I start it up and crawl under, I can feel the leak. My thoughts are to try running two gaskets?!? Anyone else have similar problems? TIA, |

Begin with the assumption that double gaskets NEVER work. Because they don't. File the pipes flat and parallel, something that may take an hour or more. Big file, both pipes at the same time, with the HE held flat on the bench. Slow and careful are the key words here. Make sure the gaskets are new, flat, and properly seated. tighten them evenly and in steps, and retighten once the engine is running. Get rid of that TON of muffler, and get something that puts less load on the system. Be sure the hanger is intact and properly secured at all 4 points. The Cap'n
