I just did my first oil change on my 2019 Ranger at 4800 miles. I planned to install the Fumoto F107N valve along with the ADP-107 adapter per the Fumoto website. I have used the Fumoto valves on my other vehicles and they have been excellent with no concerns. Note that the other vehicles all used an aluminum crush washer with the OEM drain plug.

The 2019 Ranger OEM drain plug does not use a crush washer but instead an embedded rubber style seal.

The ADP-107 comes with a a gasket washer made of a composite fibre like material. After draining the oil, on installation of the adapter, it did not seem to torque up as I would expect. I'm doing this on my back with the truck not jacked up. On visual examination of the adapter installation, it appeared that the washer gasket did not look right. On removal of the adapter, I found the gasket washer damaged as shown below.

The inner ID of the gasket washer appears to have been pressed into a counterbore concentric with the threads in the oil pan. I did not inspect the oil pan interface as I just reinstalled the OEM plug and would do a post mortem evaluation later to understand the issue. This is when I noted the deformation as shown. It still may have sealed the adapter but I did not find this an acceptable installation. An aluminum crush washer 12mm should address this concern in lieu of the supplied composite fibre gasket washer. That's probably what I will do on the next oil change.

This is just a heads up. I did advise Fumoto of my findings. They offered me a 20% discount on the F107SX style valve but I believe the aluminum crush washer will work. Fumoto was very responsive.

And for those thinking that I applied an over torque to the adapter, that's not the case. I am a licensed Aircraft Maintenance Engineer with 50+ years experience with endorsements up to the B787 and always do my own auto maintenance so I'm comfortable with my capabilities on complex machines including engines.

Just a heads up to watch for if you decide to use the F107N valve.

The gaskets def seem to be soft. I noticed mine got smushed as well using the torque wrench. However I’ve been monitoring the valves. No leaks after a few weeks.

I had the exact same problems (above) trying to torque the adapter to spec. Fumoto sent me heavier washers to try.

Did you email them or call them? I think I should get new washers even though these seem to be holding up.

Well @rpeterson53 , am I glad you posted that. I was about to Intel the same valve and same adapter this weekend. Guess I'm going to be finding some gaskets before I start this.

I dont see any pics of the fujimoto valve so its hard to say.

the seal they supply looks as if the valve contact area was not spread out enough and the seal not able to handle it. you can see the rub marks as it was tightened and it's not spread across the whole face. the rest of the design looks like it probably would have continued to seal properly regardless.
an aluminium washer will deform alot more before it fails, so it may work as an alternative.

Will do. Thanks. Checked the valve again last night. Seems to be doing well. Will get them to send me the rubber washers in case these fail. Thanks Andy

I had a thought. Did either of you (@rpeterson53 or @DIYAndy ) use the Ford torque specs or follow the torque instructions provided by Fumoto? For those wondering, Fumoto specifies 1/8 of a turn past hand tight. If you two used the Ford torque specs, that could explain why the gasket failure. That said, looking at the pictures, the gasket provided is clearly not ideal for our oil plans and I'll be looking for a more robust one today.

i did the fumoto specs hence why i don't think mine split very much(on a big screen you can see a small split). I remember thinking of both and noticed as soon as I tried to get to the torque specs I thought it would shush this washer. Here some current photos

Let me be very clear about this.
1/8 turn is ONLY for the Fumoto valve.
Fumoto recommends 15 foot lbs. (LBS FT.) on their 107 adapter for their valve.
The oil drain plug with built-in O ring, from Ford, requires a different torque value.;)
Torque: Oil Pan Drain Bolt/Plug - 20 # foot (27 Nm);)
BTW … talking direct to Fumoto and explaining my "same" problem as above they said it could be the washer and
they sent me several different washers to try?

From the Fumoto help section:

// When installing a Fumoto valve, you'll want to avoid using the specs in your car's owner's manual. Instead, you should follow ours. The chart is coded by series. So, 101 series would include all 101 series valves (F-101, F101S, F101N, F101SX, and B101SX). //

Important: when installing Fumoto adapters, be sure to under-torque. Failure to do so will lead to over-torquing while you're torquing your valve, which will add pressure to the adapter.

Series and Torque Range

101 Series: 221 in. lbs. or 18 ft. lbs.

102 Series: 221 in. lbs. or 18 ft. lbs.

103 Series: 177 in. lbs. or 15 ft. lbs.

104 Series: 221 in. lbs. or 18 ft. lbs.

105 Series: 221 in. lbs. or 18 ft. lbs.

106 Series: 221 in. lbs. or 18 ft. lbs.

107 Series: 177 in. lbs. or 15 ft. lbs

I believe the issue with the gasket is a result of the reduced contact area on the oil pan. My photo indicates this. Unfortunately, I did not take a photo of the drain pan to understand the contact area surface but based on the deformation of the gasket washer, there appears to be a slight counterbore concentric with the oil pan threads, thus reducing the contact area. I have used this same washer gasket on other vehicles I own with no issue. But those vehicles used a crush washer for the oil drain plug seal.

I believe that an aluminum crush washer will work better than the supplied Fumoto gasket washer. I found them at O'Reilly for .75 each. They are a 12mm crush washer. Dorman P/N 095-143. The idea of installing hand tight and 1/8 to 1/4 turn more conflicts with my judgement of a proper installation. What I do note is a conflict of installation instruction from the hand tight plus to the torque range published above for the 107 valve.

As I stated in my initial post, just a heads up and use your judgement. That's what I'm doing.

Cheers

Gotcha. I saw the instruction for the valve on the valve packaging, but there was nothing on the adapters packaging. My search today turned up very little. I happened to have a bunch of M12 copper crush washers, but I have some concerns about whether the outside diameter will be sufficient.

Well, I think my copper crush washer is going to work! I left the skid plate off for now to check for leaks. I took a picture of the drain plug area for those curious. There's most definitely a counter bore.
