Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
Elevated sodium in the oil samples.Solution
If the source of the sodium cannot be isolated via other normal testing of individual components (water pumps, oil coolers, and so on), then complete the following procedure:
Shut down the engine and allow system to cool.
Flip the ground level shutdown switch on the truck front bumper and leave the switch engaged. This action disables the fuel injection.
Verify that the engine will crank but the engine does NOT start.
Pull the last exhaust manifold from each bank of the engine.
Pressurize the truck cooling system, refer to Testing and Adjusting, KENR5397 for additional information.
Hold pressure on the cooling system for no more than 10 minutes for the first test. If the leak is bad, holding the pressure too long could risk hydraulic lock.
Illustration 1 g06059950
While cranking the engine, shine a light up into the exhaust manifolds and look for cylinders that are puffing steam and white smoke.
Verify any leaks by pulling the exhaust thermocouple port from the exhaust runner on that cylinder. Check for signs of moisture/steaming in that exhaust runner.
Repair any leaking injector sleeve by replacing the head.
