2017-2023 Duramax L5P GEN2 CCV Kit - JZM

Upgrade the CCV system on your 2017-2023 L5P Duramax! All billet machined parts with AN push-lock fitting included. The GEN2 CCV Kits have had their baffle design updated to address issues with some trucks having blow-by issues. This new design offers a unique air passage along with a passage to allow any oil build up to drain back thru the baffle and into the valve cover. The kit includes a 1 piece billet Filler Neck with a Cam Lok Cap (Not interchangeable with a OE GM Cap), Upper and Lower Baffle, O-Ringed AN fitting, Mating -12 PushLok Hose fitting, Seal Plate for the turbo, and the necessary fasteners.

Can be used on a completely stock or modified truck.

We have the optional breather hose that is meant for oil vapors and crankcase ventilation and is not subjected to swelling. It comes in a 6ft section of tubing!

What is the difference between the forward and rear facing?

This determines where the hose outlet of the machine baffle goes. If you'd like to recirculate the vent hose back into your intake, the forward-facing option is best for you. If you are planning to use a catch can or atmosphere option, rear is the best choice for you.
