Ok, this has me scratching my head. Changed the oil on our 2017 F-53 chassis and used the motor craft FL-820S filter as stated in the owners manual. Noticed a drip of oil running down the filter after I had run it about 30 miles. Figured maybe I didn’t tighten it enough so I gave it another 3/4 turn with filter wrench. Nope after another trip there it was again, so I decided maybe just a bad filter. Got a new filter, verified old gasket off of filter plate, cleaned surfaced and filled the filter with oil. Reinstalled the filter and topped off the oil. All was well for about 200 miles when I crawled under to check and saw a thin line with a drip of oil on the new filter again

! Trip was about 350 miles when we got home and I checked the oil level, still full. I can’t figure out why this would continue to happen, any ideas????? I can’t find any reason or source for this, no oil on the undercarriage or anywhere else for that matter it just seems to be seaping from the top of the filter somehow.

Did you add any oil to the filter prior to installation? If you have oil on top of the filter, it can drip off after a period of time. Spray the filter with either carb or brake cleaner around the mount and dry it afterward and then see if does it again.

Are you oiling the gasket?
If you could get another 3/4 of a turn on the filter then it was never tight enough.
Should be 3/4 of turn from seating position

Might be coming from the oil cooler. Its under warranty take it to ford.

Is there an oil cooler attached to the filter housing? Perhaps there is a leak there.

So take the filter off and examine it for defects. BTW, you don't have to buy the filter the manual says, there's better filters out there.

Thanks, I’ll try cleaning and seeing if it stops. The filter does attach to an oil cooler so perhaps it is coming from there. Will be having it looked at for sure if it continues, we have a trip to Disneyland coming up in 2 weeks so I hope I can figure this out before then as I’m doubtful I can get into a shop that quickly. I really hope it doesn’t turn into a major leak on that trip. I did preoil the gasket before I installed it and gave it one full turn after contact.

Did that on the first one and no defects were found, used the one in the manual to try and avoid Ford saying it was a result of a non OE part.

Make sure the rubber gasket came of with the old filter I've seen it a million times where a double gasket will leak every time.

Use a bright light and inspect the mating surface where the gasket seals for any scratches or imperfections.

Your leaving gasket on filter and just oiling one side correct. Reason I ask I saw someone remove gasket and oil both sides and it leaked bad.

Yea, I just take some of the new oil on gloves finger and coat the top of the gasket and threads of the new filter. Been doing it for years on my race cars and never had an issue. Just puzzles me as I can’t find the oil coming from anywhere else and mounting surface is clean and smooth, I even looked at the surface with a magnifying glass for any imperfections. I can’t believe I got two bad filters in a row.
I do have an appointment with a Ford service center on Friday and can’t wait to see what they find.

Just a spitball, once upon a time, I went by Napa and got an filter for my Goldwing. The filter leaked so I walked back to Napa and got another one. It leaked too. This time I took the bike to Napa. We put two more on that leaked, then went to a Purolator filter with no leak. Ended up that they had a whole batch with a bad crimp.

Crazy, I hope it’s something simple and quick like that. It is such a slow drip I can’t imagine what else it could be, maybe the oil cooler I guess if not the filter. Just want to get it fixed before we leave for Disney in 2 weeks, it would probably still make it just fine but my OCD can’t stand knowing there is anything leaking no matter how slow it is
