Have you checked the entire air inlet system for major restrictions?
Have you made sure the pump shut off system isn't staying partly engaged?

I checked for an emergency shut off on the throttle. There is none.
The air inlet doesn't have any air restrictions
The Injection Pump rack was checked under the ALDA. It moves freely and the vacuum shut off valve isn't stuck.
I ran the car directly off a clean bottle of diesel, to double check the rear tank filter. The car ran the same. Smokey.
The only two other thoughts are to check the valve adjustment and double check compression.
The compression was fine, prior to taking off head and still ran smokey.
The car also takes about 10-15 seconds to start with throttle held down to start. Almost as if it lost its prime.
