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, |

My system for almost all repairs is to tighten, drive around town a bit, then tighten again. I had a leak when I replaced my heat exchangers at first, then I slowly torqued more each day after several consecutive days of driving and it went away. The hot/cold/bumpy cycles allowed things to settle in.
Also, did you take 4 old copper gaskets OUT? You will definitely have a poor seal if you left one in there. They are REALLY hard to see up in the port, even with a decent flashlight. I had to make a special tool to get mine out. Good luck (IMG:style_emoticons/default/beerchug.gif) |
