My 307 ran like a watch. So smooth I had a hard time taking it out of my truck but my 406 was just melting over in the wrecked truck so I switched. The 307 had the infamous nylon gears when I took it apart. Bits and pieces all up in the oil pump feed tube and all in the pan. It never jumped a tooth but it couldn't have been too far from it. I suspect that if your engine passed emission test then it is also ok as far as jumping teeth. Is your vacuum gauge good? Usually passing emission tests would suggest a very well running engine as well as in good mechanical condition as well.
