Engine slobbering, oil and residue coming out of stack

A dark and heavy residue emitted around exhaust manifold gaskets on diesel engines. The operator can help eliminate the residue by avoiding unnecessary engine idling. "Diesel slobber" or "slobber" consists of diesel fuel and/or crankcase oil which has passed through the combustion chamber and did not burn. These are the "heavies" that did not burn because cylinders temperature are too low to promote complete burning.
The lower temperature occurs at:

• Start up while engine temperature increases.
• Engine is idled for a prolonged period.

Small amounts of crankcase oil can find their way past the piston rings and valve guides in a new engine or in a "cold" engine while idling. The unburned crankcase oil mixes with the unburned fuel to create the "slobber". In addition to the "slobber" you can see, there is an unseen amount of unburned fuel washing down the cylinder walls. This unburned fuel:

• Forms gummy deposits on valves, pistons and piston rings.
• Dilutes crankcase oil.
• Accumulates sludge throughout exhaust system.

TRANSMISSION TEMP HIGH on 6430 and 6430 Premium

Over the summer there were a couple 6430's and 6430 Premium's that came in where the Transmission Temperature is too high but it is full of oil. It is also pulling EGR codes and tractor goes into a power derate (engine cuts power and goes into limp mode so as to prevent catastrophic failure). The coolant reservoir if you just glance at it says it is full. However due to the design of the coolant reservoir there is a divider inside that separates the engine side from the EGR and Transmission cooler side. Make a complete examination to be sure that you do in fact have the correct amount of coolant. Don't just make a quick look at it, fully examine it.
