    Latest fluid leak with my '14 Limited V6

    Lets first start about 2 weeks ago when I noticed that the engine didn't seem as smooth at idle. So after checking the maintenance records I added a can of Berryman's B12 to a full tank of gas thinking maybe one of the injectors was dirty. She already has 71K miles on her and I have a fresh set of; spark plugs, ignition coils and a new oil cooler assembly as well as the upper and lower intake gaskets on the shelf in the garage - but no sign of the eventual oil cooler leak, hey this is a 2014 Pentastar V6 after all.

    Last evening I notice a oil stain on the driveway under the Durango and I figure well its time to change the leaky oil cooler. So after work this evening I started poking around the oil cooler with a long wire, forcing it into the valley around and under the oil cooler. Every time it came out dry - hmm. So I put her up on a set of ramps and starting looking around underneath her. The driver's side of the front differential was coated with a dark messy oil, as was the drivers side front-to-back tubular member of the front sub frame and the inside edge of the drivers side LCA. I then noticed that the bottom of the drivers side engine mount was coated as well, but nothing above or around it.

    Are these liquid filled engine mounts and if so, do I have a leaky one? While still under the Durango (after taking the pictures) I started searching the internet for Jeep Grand Cherokee and Durango leaking engine mounts. Sure enough "lookie at what I found", Mopar is on their 7th p/n for these V6 engine mounts, which means six redesigns. revisions / updates. So that is what I was noticing a few weeks ago - more vibration due to a faulty engine mount. I also watched a few videos on how much fun it is to replace them, especially the drivers side. To raise the engine up high enough to replace the engine mount, you have to remove the upper intake plenum - well if that has to come off, I might as well do the spark plugs and coils at the same time and see if the oil cooler has truly not started to leak yet.

    This evening a ordered a pair of the latest p/n I could find (68252518AA) engine mounts hoping I will not have to do this job more than once.

    Well that looks like fun....I know Lexus uses the same type of mount...they also have issues of failing before 100K.

    Some helpful tips from over on the Jeep forum;

    I just need to get my hands on a 2014 service manual for all the fastener torque specs.

    I ordered a pair of those newest p/n engine mounts and only one showed up. WTF!?! So I called the folks and they were very apologetic and offered to send out the second one next day air on their dime due to it being their mistake. Cool! The only problem was that UPS deemed the fluid filled engine mount as a hazardous material that can't be air shipped and returned the unit to the sender. Really !?! Grrr....

    So now I have to wait for the ground shipment and figure out how and when I am going to fit this job in over the busy father's day weekend or take a day off during the week, which sounds better yet.
