Keep Your Diesel Clean And Your Mind At Ease

If you drive a 2007.5-2010 Duramax LMM, chances are you’ve already put your truck to the test, and the PPE PCV Crankcase Breather Filter Kit is the upgrade that keeps it going strong. This isn’t just about extending engine life, it’s about avoiding one of the most dangerous situations a diesel engine can face: engine runaway. By filtering crankcase vapors before they make their way into the intake, this kit stops oil mist from fueling your engine without your foot on the pedal. That means more control, more safety, and less worry every time you’re pulling a load or driving in demanding conditions. Plus, it protects your turbo and intercooler from oil contamination, helping everything run cleaner and more efficiently over time. The result is a safer, smoother ride that breathes better and works smarter. Whether your truck is tuned, worked hard, or just built to last, this filter kit is a small investment with serious payoff.

Designed To Vent Pressure And Eliminate Risk

The PPE 114027500 PCV Crankcase Breather Filter Kit is engineered specifically for 2007.5-2010 GM 6.6L Duramax LMM engines to address a critical issue, controlling oil vapor and crankcase pressure. Under load or during sustained operation, oil mist can travel from the crankcase into the intake system, creating buildup and increasing the risk of uncontrolled combustion. This kit solves that by rerouting and filtering the vapor before it contaminates the intake, turbo, or intercooler. By reducing internal crankcase pressure, it also helps preserve vital engine seals and minimize the chance of oil misting or leakage. It's especially important for performance-tuned engines where pressure levels are often higher than factory settings. Built to meet NHRA racing safety standards, this system goes beyond basic filtration, it provides a reliable safeguard for both daily-driven and modified diesel trucks. Simple to install and durable by design, it’s a performance-minded solution for better engine protection.
