Finally- A Less Expensive Repair To The Oil Filter Stopper AKA THE NUB!

OK, Very long post about my journey to correct the loss of the oil filter stopper- the rubber $2 part on a metal spring that seals oil into the filter housing until you remove the filter. Once you pull the filter out the oil immediately drains and it make filter changes easy. If the stopper is damaged or missing there is a problem. In its worst case it results in "LOW OIL PRESSURE" warnings, especially at stoplights with a hot engine. In my case I did a temporary repair and the only symptom was a slow buildup of oil pressure on startup. It was only 3 to 5 seconds but it was noticeable.

There is only 1 solution Ford recognizes, and if their techs screw up and install the filter incorrectly (like I did) they will put in a new oil cooler and filter housing (Ford part # FW9Z 6881 A. The parts cost is less than $150 (more on that below) but labor runs as much as 8 hours as they have to do extensive top engine disassembly.

NOTE: Disclaimer- Ford wants the whole assembly replaced, if you do as I did you may incur a problem down the road with your warranty. Do anything I do at your own risk.

My idea was to buy the cooler-filter assembly and just transfer the stopper and spring to my truck. I also acquired a new filter canister and some beautiful metal parts. Interestingly they are labeled Jaguar-Land Rover so that alone should increase the value of my truck (sarcasm).

Here is what concerned me- the delay of up to 5 seconds before the oil pressure gauge jumped to 20 psi. Here is a short clip showing this issue- you will need volume up to hear the engine start.


Here is the same view after the new stopper was installed.


Now, here is the biggest problem with this repair. Finding the part. First I ordered it from Tasca, 2 weeks later they refunded my money and canceled the order. Next was two different ebay vendors. Same thing, two weeks and a refund from each. Global parts shortage, national backorder. Finally found one at Lakeland Ford, $111.62. (On a side note, Fed Ex delivered it but placed the box under my rear tire, almost crushed it!)

If you are still here, next we will do the step by step. First, carefully remove the spring and stopper from your new oil filter housing. I used 2 pry tools and great care, you do not want to bend the "X" that holds the spring onto the filter stud.

Next remove the old spring from your truck using the same tools.

Next carefully place the new spring into place in your filter housing. I used a socket to carefully push it into place.

At this point I would recommend you make sure the spring is up to allow oil to drain and it is on the stud properly. I actually used a few taps of a hammer on the socket extension to drive it home.

The socket applies equal pressure on the spring as you mount it on the stud.

That is all there is to it. I wish we could just order the spring and stopper assembly separately but that doesn't seem to be an option at this time. And as always, prevention is better than repairs, read the manual before you do as I did and screw up the stopper in the first place.

I would push back on exactly why the repair would not be covered by your engine or your extended warranty (assuming you are still within the warranty period(s). If those don't cover it, wouldn't the dealer step up since the part failure appeared to have been cause as a result of their oil change?

I inspected my oil stopper last week during an oil change (13th change for my engine) and it still looked to be in new condition. One thing I discovered that I have been doing incorrectly; however, was the sequence of filter removal. According to Mahle (video embedded in web link below), I should be removing the filter cartridge first, then drain the sump.

beaker: Thanks for sharing the link to the video.
A point was made in the video that was a bit of a "duh" for me . . . unscrewing the plastic filter enclosure is intended to retract the filter, opening the drain valve, permitting the filter housing to drain the oil.
For that to happen, the filter has to have a tighter friction fit in the plastic housing that it does on the aluminum post on the top of the engine.

Well, the wait is over. Just used my last oil change coupon that came with the truck and insisted a diesel mechanic change the oil. I even provided them a copy the proper install procedures. The mechanic knew exactly what I was talking about and provided me the TSB for this issue (see attachment). Apparently the "nub " is available, per the TSB. cheers!

Excellent work, @mrjake

I printed it out, the part number is ml3z-6a606-a and it seems to be available at about $12. They set a flat rate of 0.3 hours to inspect and change the drain valve and add new oil. Easy. I hope we can get the part, and that it is not on a world wide back order.

I checked with my local dealer and was informed the factory had 254 of them but they won't be released to dealers for another week or so. Price quote from dealer was $32. Google it for around $12 + shipping from what Dunrollin said.

Update: the nub & spring assembly were finally replaced a couple of weeks ago, no issues since. Surprisingly, the dealer covered the cost.

Thanks for the update. I have two of them in the glove box in case my "mechanical skills" result in needing them.

Just ordered two ($21 shipped) to have on hand, just incase 😉 Just got my new to me '19 with just over 9,000 mi. a couple weeks ago.
Luckily I found this site and the oil filter change info before I changed the oil or I would have done it like my 6.0 and probably screwed it up. Checked on the condition of the nub while the filter was out, all looks OK and pressure is good after the change. 🙂

Hey gun-driver, where'd you get two for $21 shipped? I got gouged by the dealer for just one I purchased but I'd like to get 1 or 2 more just in case w/o getting gouged again.
