Overview

The HSP Diesel PCV reroute kit is designed for 2004.5–2010 Duramax diesel engines, including LLY, LBZ, and LMM platforms. This kit redirects crankcase pressure and oil vapor away from the intake system, preventing oil buildup in the turbocharger and intercooler piping. Installation is straightforward with basic hand tools and includes billet fittings, hose, clamps, and O-rings for direct fitment.
Show original supplier description
The HSP Diesel PCV reroute kit is engineered for 2004.5–2010 Duramax diesel engines, specifically compatible with LLY (2004.5–2005), LBZ (2006–2007), and LMM (2007.5–2010) models. This system redirects crankcase pressure and oil vapor, preventing them from entering the turbocharger and intercooler piping. While not directly adding horsepower, this reroute helps maintain consistent airflow and supports optimal engine performance over time by reducing oil contamination in critical components. The kit includes all necessary components for installation: billet PCV fittings, a PCV mouthpiece plug, O-rings, 8 feet of 5/8" PCV hose, and worm-gear clamps. The product is backed by HSP's No BS Limited Lifetime Warranty, covering defects in materials and workmanship. It is important to note that while this kit reroutes crankcase ventilation, it does not modify fuel or exhaust systems. Customers should verify local emissions regulations before installation, as requirements can vary by location. The PCV reroute is beneficial for both stock and modified Duramax engines, contributing to long-term engine cleanliness and reliability.
