![]() The valves all look good - no burnt edges. We found 2 cylinders, not on the same head, that were soaked with fuel. ![]() We then pulled the heads off just to see if we could find anything that might give us a hint about why this fuel is not being burnt properly. We next went to the pump and checked to see if there were any pressure shims/washers that we could remove and try that, but there were none. ![]() We replaced the injectors, set their travel using the dial indicator method and adjusted the valves but that did not change things at all. I have a 1974 Autocar with a 370 Cummins motor (don't ask, the boss can't let go of the past) that is smoking bad from the moment you start it up.
