This is a very nicely machined item, black anodized, and equipped with a quality "K&N-style" filter. I purchased it because I noticed oil seeping around the valve cover area. I wasn’t sure if this was due to pressure escaping past the front control solenoid seals. Both valve covers were lightly misted with oil in some areas.
My solution was to install this breather. I have had a good experience these products and already purchased and installed a UPR oil catch can, which has been in place for about two years now and has collected nearly a quart of oil. I have not noticed any additional seeping, but it is a very slow and light.
From what I’ve read in Jeep forums, modifications to the late-model 3.6L Pentastar are often considered unnecessary. However, after a quick check (including consulting ChatGPT), it seems these engines can definitely benefit from a one-way breather valve.
Great service and fast shipping. The quality of the part is like a work of art. I will soon be purchasing one for my other truck.
