Motorcraft Oil Filter Catastrophic Seam Failure

[Fair enough]

Unless the pic is distorted which op said the other new one was not, it was the machinery making the base plates messed one up. Oil pressure is not going to bend out a thick piece of steel like that before other things happen. The base is misshapen, so the crimping can’t be done right.

The thick base plate is not bent - it's too thick to bend before the rest of the can will fail at some point. The pressure caused the seam to stretch and fail. Like said earlier, if there was a flaw in the seam and the seam was weak, it's possible it let go after being stressed for the few hundred miles it was installed. If there are no other signs of internal over pressure, like crushed media and/or center tube, and if the filter is not fake, then it could have simply been a defective crimped seam. If the whole can is stretched out beyond just the blown out seam, and the filter is not fake, then I'd suspect an oil pump over pressure. An unregulated PD oil pump can definitely destroy stuff ... even when there is some "pump slip".

I saw a youtube where a guy had cut open both the old and new FL1A filters for comparison. The baseplate on both of them extended all the way to the edge of the can so it should not be possible to create that dome on the end like that unless the base plate bends, OR it has the WRONG BASEPLATE from a smaller diameter filter?

The thick base plate did not deform ... it's too thick and the rest of the can is much weaker. The internal pressure deformed and blew out the base seam around the perimeter of the base plate.

Correct, it’s too thick to deform on the engine. The plate extends straight out to the crimp in a correctly formed base plate. Check WC’s pics of base plates on this filter.

How do you know this base plate wasn't formed right? The base plate itself could be perfectly fine, but the base plate to can crimp could be defective because it wasn't done right during production.

The base is misshapen, so the crimping can’t be done right.

What makes you think that?

Picture for a better look at the construction of the base and seam. For more arguing. The secondary base cover is the one with the seam to the can. This is a drawing really not a picture. Purolator has a second plate that goes into the base plate holes. PG has copied this it must be good. Other cos. end it further out and put some glue inside. I think Puro also glues the center part of the seam plate.

So, if the can flexes out at the base, oil pressure can get to the secondary plate and possibly bend it out. The thread keeps the gasket tight to the bending is outside of the gasket. The base plate itself doesn’t need to flex and is too thick to flex. I wonder if louvers are closed? Pressure increases fast even as the relief valves open.

What is the best alternative to motorcraft. I cant keep up with all the buyouts and mergers

Do I want duraguard which is relabled m2 filter made by Krupp bought out by Acme and produed for Nope-A? Or was that yesterday and now its thingamagig watchamacall it which is relabled EverQuest filter made by germans but was bought out by japanese and is made in taiwan which actually shipped it from china and "washed" the label and now its made in taiwan but it a temu filter...
welcome to 2025

Lots of love here for Premium Guard, Pentius, Carquest Premium. Totally agree though; some that used to be top notch have fallen and it changes often!

Most oil filters are basically built similar to this. It's possible there is no type of sealing where the red arrow goes between the can and the end of the thick base plate. Yeah, the base plate doesn't flex, it's way too thick and it's designed that way for a reason. It doesn't even flex outside the circumference of the base gasket (blue oval area), it's too stiff for a short cantilever length like that to have any real flex.

So oil pressure gets in the area where the green circle is, and if the seam crimp is defective and weak then it can blow out just like seen in the photos in post #1. If there is supposed to be a bunch of glue in that area to seal and strengthen the seam, and it was missing due to a production error, then that could be a factor too.

Yes, it's possible this filter has very choked down louvers, but the OP needs to open the filter up for more confirmation on what's going on inside. Even a good photo down the center tube could show if the louvers are choked down a lot or not. Choked down louvers are bad for many reasons, as mentioned in dozens of threads discussing louver formation.

Just take a tin snips and finish opening it up. It won't take 20 seconds.

Looks like the seam has totally unrolled. Put on some thick gloves and try to twist it apart.

Repeat of what I said. You’re telling me what I wrote as if I didn’t write it. That’s ok. The crimp is a drawing, the can should turn into the curl in the crimp. The adbv is wrong too. It’s for general illustration.
Mopar filters which are practically identical, specify a glue filled seam in the advertising. I used to buy those instead. Unless they too went to China.
So to OP, you can buy mopar filters too.
The thin baseplate cover could have been made defective. I now see the thick baseplate is not directly pressed against the thin cover baseplate.

You're not the only guy on the site ... it's added info for others with some illustration to better describe what's going on. You sure get bothered when anyone replies to your posts, lol.

Must be some current M+H/Purolator "quality" ... they can't even illustrate a build configuration correctly. The louvers however look pretty choked down, which might be pretty accurate.

The illustrators are more honest than Purolator’s marketing department.

It’s been like that a long time. It doesn’t have to be a photo or they could take one. It serves the purpose as an illustration. Oh, I thought I was the only guy on the site. I am not sure it’s all guys. Errors from advertising illustrators are not uncommon. Don’t look at your box of cereal illustrations too hard in the morning. Or the meal you get illustrated on the menu at a restaurant.

Who said or who thinks it's not an "illustration"? They obviously don't have anyone giving the art/illustration group any technical information to get it right. Upside ADBV ... classic, maybe they based it off a real filter off the production line, lol. And probably anyone here could draw louvers better than in that "illustration".
