The oil bypass valve is defective on the 2011-2013 3.6 L Pentastar engine. Apparently this part has been snapping off under the oil cap, and dealers are charging $400 w/labor to replace the entire assembly. Before this happens, you can buy a Dorman replacement bypass valve for $14 at: http://www.rockauto.com/en/catalog/...v6,1447819,engine,oil+filter+bypass+valve,720 Also the Wix and Napa Gold oil filters (#7526) have also been updated. They have a new assembly inside the top of the filter, not a open hole like the old ones.
