The heads on your commercial or fleet diesel are one of the most integral parts of your engine. The heads are comprised of the valvetrain, exhaust ports, intake ports, and injector ports. In essence, a head’s purpose is to regulate and time the intake of fresh air, the release of exhaust, the compression of fuel and air that provides combustion, and the entry point for fuel into the cylinder.

The oil absorbs tiny debris and contaminants, kind of like a liquid sponge - once it’s at capacity, that oil begins to stick, clog, and build up throughout the engine. Small veins that carry oil to components like actuators, turbos, and bearings will become blocked, starving critical components of oil and causing component or engine failure.
