Keep your modern GM diesel intake tracks completely free of oily residue sludge, carbon tracking deposits, and intercooler heat soak. Our collection of heavy-duty crankcase ventilation (CCV) upgrade packages, reroute kits, and CNC-machined billet aluminum bypass block-off caps are engineered to redirect oily crankcase blow-by gasses safely out of your induction system. Swapping out the failure-prone factory plumbing layout on your 2017-2026 6.6L L5P and L5D 6.6L L5P, LML, or 3.0L LM2 and LZ0 Duramax engine ensures a continuous supply of clean, pure-density air mass to your turbocharger compressor. This critical modification permanently eliminates oil pooling inside your intercooler cores, prevents boots from blowing off under high boost, and preserves maximum turbocharger blade efficiency whether you are towing heavy payloads or running max-effort street calibrations.
