• Designed to handle high-pressure oil flow

Oil Pressure Regulator Valve

The oil pressure regulator valve plays a critical role in maintaining safe and stable oil pressure levels. In the Detroit Diesel Series 60 11.1L, it prevents over-pressurization at high RPMs while ensuring sufficient lubrication at low speeds.

When the oil pressure exceeds the set threshold, this valve opens to divert excess oil back to the sump, stabilizing system pressure and protecting components like filters and seals.

Common Signs of a Failing Regulator Valve:

• Fluctuating oil pressure gauge readings

• Premature oil filter failure

• Engine ticking or knocking sounds under load

Replacing the regulator valve during maintenance or when installing a new oil pump helps ensure a balanced and efficient lubrication system.

Oil Pan Gasket for Series 60 11.1L

The oil pan gasket creates a seal between the oil pan and the lower engine block, preventing oil leaks that could lower the system’s volume or contaminate other components. Diesel Pro Power offers durable rubber and composite-style gaskets for the Series 60 11.1L.
