Motorcraft FL-910-s failure

[guitarandoil67]

FL-910-s with 4000 miles with motorcraft full synthetic 5w-30 cut open and top end cap was disconnected

 

[Hootbro]

Yeah, not really considered a functional failure since the media was still contained by the end cap and glue.

I had the same issue on a FL-910S also.

 

[Fair enough]

It would be useful to know the date code. Not good performance from filter, but oil looks good.
There is a piece of glue loose in the center tube. They should use the Boss glue, wonder why they know so little about their oil filters. Because administrators often know little about what is going on in the actual manufacturing.

Nephews Ford Escape FL910S had the top end cap separate when I pulled on it to get it out after cutting open, just figured the 11k change pushed its boundaries too far.

Replaced it with a Carquest Premium 85348.

Use a FL-400. That's all I ever used on my 4cyl mariner and on my X-Mark

Not high quality bonding but certainly not a failure.

Not high quality bonding but certainly not a failure.

The best kind of failure to have

 

[Gravity_Wolves]

Probably too much back pressure from choked off louvers

Then it would have been in bypass the whole time.

This really concerns me….

I know common group think here is this is generally harmless, but wouldn’t it functionally be the same thing as the much disparaged leaky bypass?

That and there’s a piece of glue breaking off into the center tube. It’s a fail.

 

[scoot]

Huge fail no wonder Ford has VCT failures . One chunk of that would do it

I stopped using the 910 after about 400,000 miles of use in Ford Duratech engines because of the black glue showing up in my oil change pan.

What did you switch to?

When it's together in the can it doesn't leak like the ripples. Doesn't scream high quality when one of the end caps fall off after cutting though.

 

[Glenda W.]

If I had to guess the ones with clean dry glue aren’t leaking. The ones with dirty oil on the glue are.

Filters designed with no end caps have special designed center tubes. Like below.

It's what I would expect from a 3.97 filter (2023 price)

If it's not adhered to the glue and just pops off, I don't see how it's any different than a leaky Fram bypass. The oil all over the glue seems telling.

I'm not clever enough to figure out how to do a flashlight test on one of those but I don't have a popper anyway.

What did you switch to?

Right now the Fram Ultra 3614 oil filter
