Hey all, just wanted to post my 2 cents in here since I JUST got my Jeep back from the dealership for the filter housing replacement, finessed it to a point that I was able to save some money even at the dealer. Mine is a 2014 Cherokee Limited 4x4 AD1 with the 3.2, and sure enough all signs pointed to the oil filter housing. Granted i consider myself somewhat lucky since I experienced this at 116,000 miles whereas most I’m seeing are happening around the 45-80k mile mark if not more than once. Lift off your engine cover and shine some sort of pen light down by the side of the oil filter tube, if you see pooling oil in down by the housing that’s a pretty good indicator, that or if you have large amounts of oil under the car in multiple spots rather than just one as if the oil pan or screw seal was leaking. Also that housing has the oil cooler, five or so gaskets underneath, and a few sensors on it as well. So if your CEL comes on as mine did and throws the code PO6DD for the oil pump, it‘s killing a few birds with the same stone by replacing the entire filter housing adapter.
So first things first, FCA designed that filter housing very poorly being composed of plastic. Doesn't really matter the type of plastic, nonetheless its plastic. It’s either going to wear down and warp over time from temp fluctuations by running your car or be broken by some shop junkie over-torquing the filter cap during an oil change (hence why you do it yourself and tighten the cap to spec). Original part number was 68105583AA, to be replaced with the same part number however ending in AF. Beyond frustrating that FCA wouldn’t warranty or recall the part knowing (pardon my French) damn well that that part was susceptible to failure and changed it in models from 2015 and moving forward; especially since that much oil leaking down the engine and onto multiple mechanical components to an extent can cause a fire hazard. Not only that, but the day before i took it to the dealership I checked my oil just to see the progression of oil loss, and not a single drop even registered on my dipstick on the first pull!! About gave me a heart attack so it went straight to the dealership.
Clearly you can tell my frustration, but rant over. Here’s how i was able to save a few bucks. I live in a pretty big metropolitan area with multiple CDJR dealerships; so before you do anything shop around. Most likely the dealerships are going to tell you they need to diagnose it first, but if you’re 100% certain like I was then just ask them what their labor rate is and how long they predict it taking. It’s perfectly acceptable to request the service advisor you’re speaking with to ask a mechanic how long on average it takes for the job as I did. Also, try to find a dealership that has the option to order the parts from their own dealership to be readily available for will call at their parts department, this alone saved me about $200. I honestly would’ve done the work myself, but with removing the upper and lower manifolds and risking something falling inside the cylinders, I’d rather that type of work be warrantied by someone in case it decides to blow up on me later. I’ll list all the parts and their respective part numbers, and it’ll behoove you to grab six quarts of oil from a department store or somewhere rather than paying for the dealerships inflated cost. No need in picking up the oil filter as an OEM Mopar filter will come with the new housing adapter.
Everything you’ll need:
Mopar Oil Filter Housing/Cooling Adapter: 68105583AF (1)
Plenum Intake Gaskets: 05184562AC (6)
Lower Intake Gaskets: 05814331AC (6)
50/50 Mopar Coolant: 68163849AB (1)
6 Quarts SAE 5W-20 (or whatever your vehicle requires)
A few notes for the service:
1. While it was at the dealer they tried to charge me for an oil change service when that’s already part of the process required to replace the filter housing, so don’t let them take advantage of you. And like i mentioned before, take your own fully synthetic oil and leave it in the car and tell them to use it.
2. They contacted me the day before I picked it up to tell me that the entire engine timing cover needed to be resealed (after they already reassembled everything from the previous part) and quoted the part at about $74 but labor at about $1,200!!! I would understand if they wanted to go at it while it was already torn apart for the first repair, but that just made me mad. He sent me a picture of some residual oil on the timing cover, which most likely is from the original leaking problem and the timing belt slinging oil all over the place. Pick up some brake cleaner or simple green and give the engine bay a good spray and gentle wash. Be careful to avoid any important electrical areas and don’t pressure wash too strongly to avoid getting water where it doesn’t need to be. Been parking in the garage with cardboard under the car and so far not a single problem.
3. They may inform you that because of the oil problem causing strain on the engine that theres sludge in the engine. Rather than paying them an astronomical amount to do an engine flush or whatever they convince you to do, simply changing your oil more frequently a few times at about 5,000 miles per ought to expel most of that sludge. You can cover your oil draining pan with some sort of cloth and you’ll see all the remnants left behind after the oil drains through.
Sorry for the terribly long post! Wanted to be as informative as possible since I just noticed someone posted a few hours ago. Feel free to reach out if you have any other questions.
