What is L5P CCV Reroute?
The CCV (Crankcase Ventilation) system routes blow-by gases back into the intake.
Why Reroute or Delete CCV on L5P?
On L5P Duramax, the factory CCV setup might lead to oil buildup in the turbo and intercooler. Over time, it causes carbon deposits, intake restriction, and reduced performance. Also, factory CCV lines are prone to cracking under heat, while plastic ports are not serviceable and sit behind the driver-side valve cover. Replacing the stock system requires removing injectors and fuel lines (which is very labor-intensive), while our L5p CCV reroute/delete kit reroutes blow-by vapors away from the intake using a durable external L5P CCV filter.
L5P CCV Reroute/Delete Kit Key Features

Moreover, this l5p CCV reroute/delete Kit supports both reroute and delete applications for the L5P CCV system with simple installation.
