I tryed to tighten the bolts on the 2F's exhaust manifold /Header to stop the leak. I found a couple of bad bolts that I was fortunate enough to find good threads with a slightly longer replacement. I tightened in hopes to stop the leak,only to discover the torque specs is a measely 30 ft/lbs torque. I doubt if I'm gonna stop the leak at that,so a gasket replacement is likely. From what you posted previously,I should use 2 gaskets this time,the 'green ones' from SOR, and use copper RTV gasket seal. Should I coat both mating surfaces w/ the copper sealer AND between the 2 gaskets? I may need a couple of tubes,huh?Also, on the inline-6,does the the radiator have to be drained like the Ford 302 8 cyl.? I'm learning this motor as I go. This will be my first manifold gasket job. Any tips? If I find the mating surface isn't straight,especially the rather thin header, how do I straighten it?
