My 3 cylinder Case (built by David Brown) is showing diesel smoke
and has a miss. I bought it 12 years ago and at that time I had to
have injectors and pump rebuilt. I had the injectors bench tested and
they are all in spec. At idle or low RPM tractor does not smoke or
misfire. Can an injector possibly fail when under load of
compression??
 
Isolate it to a specific cylinder by cracking the pressure lines to the injectors one at a time listening for a difference. Then swap the injectors between the problem cylinder and a good one. See if the problem moves.
