Check/change the manual fuel lift pump, front pax side-lower corner of the block...... it could be the culprit. They can leak into the oil pan if the diaphram is fubar.

How is the coolant for clean/oil??????

Do check the batteries and the starter for condition, batteries should be minimum 850CCA each or better. Starter should spin the engine faster than you can count revolutions......200rpm+

Since yours is a 94 there should be no way the fuel is getting into the oil pan via the injection pump unless yours has an old style pump not the 5013 non turbo or the 5070 turbom IP. Did you get the right code injectors...... is this a turbo or non turbo motor.

Please be so kind as to put much needed info in your signature, go to "My Home" at the top of the page then "Personal info" click "Edit" put "all known" particulars for your truck/van in the signature block, any other info you feel worthwhile in other parts of this area. Fill in the "geographic location" too it is just as important, members can then direct you to the best known suppliers for parts, repairs, fuel etc closest you by location/ area/country. You could be just around the corner from a member willing to assist you or a parts store with what you need..
THANK YOU

Evaluating Normal Diesel Engine Exhaust Smoke

The following is a description of what is normal and expected exhaust smoke for a vehicle with a diesel engine. Diesel exhaust smoke can be classified into two categories according to the color of the smoke.

NOTE:
Chassis fuel system air leaks may also cause continuous heavy blue-white smoke.

The first category is blue-white smoke.

l Blue-white smoke may be observed at engine start-up whether the engine is up to operating temperatures or not. This start-up smoke will be observed at all ambient temperatures and should last no longer than a minute after the vehicle is driven.

l When ambient temperature is below 10°C (50°F), blue-white smoke can return after the engine warm-up due to extended idling. This is due to the combustion chambers cooling down during periods of extended idling time.

Heavy blue-white smoke will also occur when the engine is operated at wide-open throttle (accelerator pedal to the floor) with the transmission in NEUTRAL or with a lightly loaded vehicle in any transmission gear setting. The smoke is a normal characteristic for a diesel engine with a light min.-max. governor spring in the fuel injection pump. This results in the following characteristics due to the engine operating above its rated speed (3300 rpm) in a no-load or lightly loaded condition:

* Heavy blue-white smoke.

* Fuel injection pump governor hunting resulting in high speed engine rpm surging.

* Engine sputtering or misfiring.

The conditions can be eliminated by operating the engine at or below its maximum full load rated speed of 3000 rpm.

The second category of diesel exhaust smoke is black smoke. Black smoke occurs whenever the engine is working hard. The engine works hard when it is going up a steep grade, pulling a trailer, carrying a heavy load, or during acceleration. More black smoke will be observed when operating the vehicle at higher altitudes. If black smoke is observed while the engine is idling (at low altitude) or under normal driving conditions, the problem should be diagnosed as soon as possible.
