My 80 Buick 350 is hanging about 3 feet in the air from a crane beside my 76 Century so I can put in a TA poly rear main seal. Do I have to loosen all mains or just the rear? What is the torque sequence for the main crank bolts when I tighten them back up? Do I need to use anything to hold the seal in place in the block? I'll post pics of my progress.....
