Recommendations for cold weather starting
          

Symptoms

During cold weather, black residue is being emitted from exhaust manifold split flange.

Situation or Problem

Small amounts of crankcase oil may bypass piston rings and valve guides in a new engine or in a "cold" engine while idling.  Unburned crankcase oil mixes with unburned fuel to form residue or "slobber" which may be expelled from exhaust manifold gaskets or exhaust manifold split flange.

The internal starting aid alters fuel injection timing to enhance starting. Operating time of the starting aid is dependent upon coolant temperature and throttle position. Use the following procedure: Place throttle in SLOW IDLE (900 rpm) position.
Avoid unnecessary engine idling. Operate at minimum of 1200 rpm if idling longer than three minutes.
Engine may run less smooth and have increased diesel knock after the end of starting aid cycle. This is normal, the engine will run smoother as engine temperature increases.
