Our 2950 diesel tractor has been sitting for at least 15 years due to a never fixed hydraulic issue. Anyway, we decided to have a look at it to get it back in working order.
Started with an oil change, new filter, new inner and outer airfilter, drained the old fuel, new fuel filter.
It was tough to get her going, but it started eventually. Ran like crap, really loud knock, couldn't quite figure out where it came from, also white exhaust smoke.
Started with Testing each injector by cracking the individual pressure fuel lines, 5 of the six responded immediately when the fuel supply was cracked open, one injector did not respond when the fuel supply was cracked, but the white smoke disappeared and the knock sounded less?
So we replaced the 'faulty' injector, which was a son of a gun to get out. Started it up with the new injector, the knock is barely noticeable or maybe I just hear it in my imagination, but we still have the white smoke, which stops when we crack the fuel supply to the new injector.
Why would that be? Where do we go from here?
Thinking of opening up the valve cover next to see if anything looks odd, just don't want to start tearing things apart if there are other things we could look at prior?
Help please.
