The Bronco is a 83' with 135K on it. We did a compression test on the engine today and the numbers are from fornt to back 139, 141, 150, 151, 150, and 141. Which a friend of my said are good, however, I still have a lot of oil smoke coming from the crankcase fill hose and the pcv hole as well as a slight amount of smoke from the tail pipe. If anyone knows what the compression is supposed to be or if anyone has a answer to my smoking problem let me know I would appreciate it.
