Does anyone have some sort of book lying around that they could look in and tell me the camshaft journal diameters on a 1979 728i. Or, would they know someplace where I might find this information. Perhaps someone has access to a "Motor's Manual". They have been known to have such information. My car is down, and I need this information to base my decision on which way to go. I can find information Sunday (hopefully), and proceed Monday. TIA,
