What is there left to do after filing the end of the heat exchanger pipes, installing new copper gaskets, and torquing to 18 ftlb? I know some say torque untill the leak stops but when pressurized only with the shop vac at least three of the four joints were leaking. But at what torque do the studs pull out?
The car is a 1.7 1973 with 1.8 heads so I used the larger copper gaskets. I'm going to take it apart again. measure the joint to flange dimension, and file the mounting ears if needed. Anybody have any other ideas? Nick |

Mark the tops of the pipes with a black sharpie prior to filing. Use a big bastard file so you do both on one heatexchanger at the same time on each pass. Only take off as much as needed
