Hmmm….

 

[Dunrollin]

@Dijit The measurements are probably metric but here is what I found. The machined surface the stopper rests on is right at 3/4" across. The hole itself is close to 3/16". A 3/16" drill bit fits great but a 13/64" bit is too large.

Hope this helps!

Send a sample and these guys will mass produce them- and material or color.

Thinking of the suction cups @Digit found on Amazon . . . wondering if there may be nitrile suction cups findable? My understanding is nitrile is likely to be appropriately resistance to heat and oil. Silicone rubber may also be an appropriate material.

 

[STIAJW]

This suction cup is pretty close, if it were made of a heat and oil resistant material, if the outer ring of material is trimmed off, and the hole in the metal spring is drilled out to ~1/4".

An alternative for the nub / anti-drain back plug?

I wonder if this is made / available in a heat and oil resistant material.

Good point. I think I’d have to put one of these in some oil/heat and see if it’s able to hold up before I throw it in my 3.0.

If someone can come up with a part number I’ll bet Granger or McCaster Car or Amazon has them by the thousands

This part 1670K2 on this McMaster Carr page may work McMaster-Carr. The hole in the metal spring would need to be drilled out to 1/4" or a smidgen larger.

Great work @STIAJW. I like the looks of that. That round head should take the filter rub better.

Silicone is the more heat resistant material, it’s what is used for space craft re-entry heat shielding.

The description is for "SBR rubber". A quick search didn't show whether it is long-term oil resistant. That would be a critical property in this application.

Solved my nub issue by trimming down a rubber bumper from a 60s glove box door bumper and installing it back into the original position. No pressure loss in 12k miles. Problem solved.

Please let us know how it looks the next time you replace the filter.

Sounds exactly like what I stared experiencing after I had an oil change done on my truck. Low oil pressure warning started about a week after the oil change, the first time I was between the garage that did the oil change and the dealer where I bought the truck. Went back to the garage, checked the oil, it was full, they weren’t really sure what the cause could be, stopped at the dealer, they looked it over and could find any obvious signs of leaks, but since it wasn’t OEM oil they wanted to start there.
Had the dealer do another oil change a week later, took a drive that afternoon and still had the low pressure warning. Went back, the service advisor was able to witness the warning, went it to get the shop foreman, and by the time he came out and plugged in the warning wouldn’t come back. Scheduled to replace the pressure switch/sensor, job completed, took a drive when I got home te same day, warning came back.
By now I had noticed that it happens when at operating temp, in gear at idle. Mad another appointment for them to have the truck a few days so they can drive it and do a live feed scan.
Got a call from the service advisor today saying that Ford released a TSB a day ago covering this issue, he’s ordering the part to hopefully have it on hand next week when they have my truck. Unfortunately, it doesn’t look like Diesel engine or extended warranties will cover it, but he’s going to try and get them to eat some of the cost. He has the same engine in his truck and hasn’t experienced this issue, nor have any other trucks they service.
If they determine this is the cause, is replacing the spring and Nub difficult to do?

 

[Dunrollin]

Wow, I want to see that TSB. Should be very interesting. I am guessing Ford is getting tired of replacing the entire oil cooler to solve this. So far that is the only Ford authorized cure we have heard of here.

We are still experimenting with the best ways to do this without the day of labor to pull the oil cooler, as you can read above. I can go out to the garage right now and have the spring out in 10 minutes, back in within another 10 minutes. The issue is the rubber stopper itself, or as we have termed it the "nub", is no where to be found. It would be wonderful if Ford sold the spring and nub as a unit. From what you are saying maybe they will be offering it!

Please keep us informed of your progress, and thanks!

 

[STIAJW]

It would be wonderful if Ford sold the spring and nub as a unit.

Agree. A simple fix to a problem from a vulnerability that shouldn't exist.
Unfortunately, the simple fix doesn't solve the root cause of the problem where changing the oil filter can dislodge a $0.25 part resulting in too low oil pressure, which can only be not good for the engine.

 

[jmperlik]

TSB # please! We have been asking for something like this for the last year, so we are very interested in what it says! We did see what we think is a new design for the rubber stopper, so hopefully that are selling it as an individual part now.

 

[Doc Nelson]

All,

Ill see what I can do about getting a TSB #. Last time I was at the dealer was Wednesday and nothing was posted. My service advisor called me this afternoon and literally said it dropped within the last 48 hrs.

it’s nice to see that the issue isn’t unique to my truck.
