I've got the same oil leaks as you by the sound of it Mark. I too would have thought that after spending a considerable amount on reconditioning the mechanical parts on my truck that I shouldn't see oil spots on the garage floor, but maybe it's just the way things are with these old vehicles?
After working on my weeping oil issues, I still have a slight weep from the bottom of the timing chain cover, a weep from somewhere in the front of the gearbox, and now a new weep from the speedo cable at the gearbox end. I'm hoping that they will be less noticeable after I change out the 'running in' oil after I clock up a few hundred more miles.
Let me know if you find a solution to the problem as I would be very interested in waving that same magic wand at my truck.
