Hi - in process on my '75 1.8. I removed the heat exchangers, exhaust manifolds, heater boxes, etc. because the exchangers rattled, boxes were rusted shut and exhaust leaks were pouring from the copper gaskets b/t the heads and manifolds....So...

Took some exchangers from my parts car ('75 1.8 also, identical to my resto), cleaned and painted (hi heat paint) them and the manifolds, bought new copper gaskets, aligned and adhered the copper gaskets to the top of the manifold (I was very careful on this alignment) and replaced all on the car, careful to torque the nuts to 18 lbs (as per Haynes).

I cranked her up and .....same exhaust leaks from around the copper gaskets.

Any recommendations on how to fix??
