I cant seem to keep my Dasa from leaking right where it joins with the head. I cant seem to get it tight enough ever. I bought a new gasket and tightend the two nuts and after a 2hr run at the dunes it is leaking again. I looked in my service manuel and it said only 15lbs of torque on the 2 nuts. That is like finger tight. Is there a proper way to tighten the nuts? Is 15lbs enough? Someone help me. most everyone in here has the Dasa, has anyone else had this problem? How much does it take to smash the copper gasket properly?
