2012-2016 Duramax LML PCV Valve O-Ring
This viton o-ring we offer fits the 2012-2016 Duramax LML. It will not fit 2011 models!!!
The reason we have this o-ring available is because GM does not sell the OEM replacement. They make you purchase the whole PCV valve to get the o-ring. This has been tested and fits our ventilation plate which can be found HERE
The PCV valve is located on the back side of the OEM intake horn, just above the turbo. The factory o-ring is orange.
We keep these in stock.
