Do all old trucks leak or is there an acceptable amount?

Yes very good if installed correctly. Like a oil filter gasket, a film of oil is good to help squish and also assist release upon replacement. If using on a pan, timing cover or intake, be sure to dab a bit of RTV in the appropriate corners. No gasket will seal those areas. Last point is the front and rear arch of the oil pans. I found them not to be very snug on the 2 pans I attempted to use. I gave up on finding a good fitting reasonably priced pan. A liberal bead of RTV has held well. Last on your statement of using RTV like calk. I did so on a weep of oil in the arch area between pan and timing cover with success. Cleaned with brake cleaner, and run a bead. Smear and crossed my fingers.
