A worn or sticking oil pressure relief valve lets oil pressure wander, reading low at hot idle or spiking on a cold start. Replace it with the genuine Cummins 3936365 relief valve.

• Genuine Cummins: The factory relief valve, so it matches the original spring rate and fit.
• What it does: Regulates engine oil pressure by bleeding off excess flow, keeping pressure in range across idle and load.
• Fitment: 1989-2018 Dodge Ram and Ram trucks with the 5.9L or 6.7L Cummins.
• Part number: Cummins 3936365.

Order today, and check your oil pressure with a mechanical gauge before and after so you know the valve was the cause.
