What component distributes lube oil to all points in the diesel engine?

• A. Header
• B. Pump
• C. Return line
• D. Strainer

Answer: (A)

In a diesel engine lubrication system, oil is moved under pressure from the pump to a central distribution point called the oil header. The header functions like a manifold, taking the pressurized oil from the pump and routing it through separate feeds to all lubrication points—main bearings, crank journals, camshaft gears, pistons, and other moving parts. This distribution ensures every critical bearing and surface receives a steady supply of oil for lubrication and cooling. The return line is for sending oil back to the sump after it has circulated, and the strainer cleans the oil before it reaches the pump or header to protect components from debris. So the header is the component that distributes lube oil to all points.
