Ya I've seen quite a few threads on this but I was wondering how I can tell if my truck needs to be timed. About 6 months ago I replaced the pump and I did notice it smoked more but didn't notice fuel mileage change because I never really drove it before changing the pump. It sounds like it runs fine to me but to be on the safe side I went to a local diesel shop to see if they could time it. They told me "you don't need to time these motors" and he also told me they won't touch my truck because its an ancient motor. Needless to say ill never go back there again. I also know quite a few people on here have timing meters but unfortunately I'm far from most of the people on this site
