I just rebuilt my 4.7L 289 out of a 1968 mustang and initial start/warm-up went smooth except my rear main seal doesn't seem to be holding. I don't own a engine or car lift and I was wondering is the a feasible way to replace the seal without pulling the engine? Can you loosen the main bearings and lower the crank enough to replace it? Or lower trans?
