Hello! Let's see if we can work together and come to a satisfactory conclusion!

Expert:  Curtis B. replied 11 months ago.

What engine? If you loosen one injection high pressure line at a time, at the injector nozzles on the head, does smoke continue, or can you isolate it to one cylinder? Can be one bad injector nozzle.

Has the air filter been replaced?

Customer: replied 11 months ago.
We haven't changed the air filter but it looks fine and has been blown out.

Try loosing each injection line to see if it is coming from a single cylinder.

Customer: replied 11 months ago.
Should we bleed the entire system down and restart. Could air in the system be causing this?
Expert:  Curtis B. replied 11 months ago.

No, just test each injector line.

Customer: replied 11 months ago.
We are going to check each injector and will let you know.
