Oiling System

The Cummins 5.9L turbo-diesel oil pan sump was modified to increase ground clearance and to add oil capacity.

The modified oil pan features internal baffling and trap doors to keep the oil around the modified oil pickup during high-G loads on a road course.

A Moroso high-capacity racing oil filter is remotely mounted on the fenderwell to provide easy access, and to provide extra space for the turbocharger ducting.

The Cummins 5.9L oiling system remains stock except for modifications to the oil pan for extra ground clearance and oil capacity.

The oiling system of the Cummins 5.9L turbo diesel was given careful scrutiny and deemed adequate for the power levels anticipated by the modifications that would double the engine’s torque and horsepower output. However, the oil pan required modification for two reasons. First, the depth of the oil pan sump had to be reduced to provide necessary ground clearance once the engine was installed in the Project Sidewinder Dakota. Second, internal baffling and trap doors would be required to keep the oil around the oil pump pickup during the dynamic movements of the Sidewinder on the road race courses.

Consequently, the oil pan was modified with a wider, but shallower, sump. The new sump actually holds more oil than the stock sump, and it contains all the necessary baffling and trap doors to prevent uncovering the modified oil pickup during high-G turns, braking, and acceleration.

A remote-mounted high-capacity Moroso oil filter handles the filtering chores.
