Pe4rkins 4-108 smoking at idle and smells like diesel

Hi All,
Just had my injectors and injector pump rebuilt. At first no real noticeable issues. Now after about five hours of time on the engine I am developing smoking ( a lot when first started, none while running at rpm, and some when the engine is warm and at idle), and the exhasut smells like fuel. What gives? thought my problems were solved with the rebuild.

What color is the smoke?
Blue=oil;white=water
Black indicates incomplete combustion. Take it from there.

incorrect timing can contribute as can old fuel

Theres almost always a little break in in the first 8 to 10 hours, and a miner adjustment to fuel timeing maybe nessary At least thats been my findings when I set up someones engine I always ck back to see if adjustment is needed. Should be no big thing !!!

Bleed the air at the injectors first.

Then have your mechanic set the timing if need be.

Does the engine seem to firing on all cylinders?
