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, |

if you went thru the torqueing sequence and ran them up fully as you put them on, you may have cocked the he's with a built in leak. did you lightly pass a big wide file over the tops of the pipes, one side, both pipes at one time? try just loosening all 4 nuts so the he is just free. press it up so you can feel full contact and no rocking of the he. with you free hand take the torque up in a few passes. just reefing down on the nuts trying to cure the leak could be disasterous. be careful.
