Only ever had one weep a bit, and that stopped weeping oil after a few hundred miles, and no it didn't run out of oil, just went from a nasty trickle to totally dry over the course of a weeks commuting, lost 100ml in the first 20 miles, I thought it was a bad un then, 40 miles later it had inproved a lot. That was a Usa inport engine, I think as the seal was warmed and softened by oil it regained its integrity.
