Metal Specs in Center Tube/Core of New Oil Filters?

[Carlostrece]

In another thread, Fair Enough posted: "I was doing more home oil filter inspections and put my finger, small one, into filter thread holes and wiped on the inner core. Some came back with metal particles. Used a bright led light on my finger, yep, considerable differences. Purolators I have three, were very good. Pentius and Toyota a little tiny bit of bright specks, and my Frams that came yesterday, quite a lot. This all goes into the engine on first start with the new filter. If I could find a magnet I would see if it’s steel. 99% sure it is and from the center tube. Not from the threads."

Has anyone checked for the above issue in Premium Guard, Microgard Select, Napa Gold, Carquest Premium, STP XL? How about Fleetguard and AC Delco Ultraguard Gold?

Would it help to sweep the interior of inner core with a magnet or vacuum prior to installation?

I suppose another possible solution would be to buy Purolator One since Fair Enough indicated he has not found particles in new Purolators.

P.S. - The reason I didn't ask these questions in the other thread where Fair Enough posted about particles in new filters is that other thread got locked before I could post these questions. The questions I asked in this thread are not related to anything that got the other thread closed.

Should've seen the post from one member here that busted out their vacuum to see how much media etc came off the filter. It was actually quite interesting!
Hopefully, you'll get some bites on your question though.

Perhaps a vacuum is a better idea that a magnet?

Interesting. I’ve found badly cut threads with metal slivers inside Fram Endurance’s before. I know some vacuum out filters before use

So what's your vote? Use a magnet, vacuum, buy Purolator One, or don't worry about it?

I guess the vacuum would be the easiest. I don’t buy M+H or First Brands products anymore so the Purolator One is out.

I inspected the threads on 2 MircoGard Select and 3 Carquest Premium filters, and they were all cut well and clean. Best practice is to inspect any filter, regardless of brand.

Use a small shop vacuum hose on the base plate center hole to suck air through the filter and out the center tube. If anything is loose it should bet swept out and into the vacuum cleaner.

Now I have ANOTHER weird habit to explain! It sure can't hurt, and it could catch "trash" that otherwise is going who-knows-where in the engine...

OK stepping up into the red zone here...I have a car that has a simple 8v 1596cc engine which is non turbo and has been tuned to a 39% increase in output via traditional methods and increased fueling.

Now having spent a few hours trying to find an answer to my question across the internet I am going to post it here on this open thread ok?

So.

Why do MANN W719/43 & MANN719/12 filters have perforated "center" cores whilst the likes of MANN 940/24 have unperforated "centers" ?

I'm just trying to find an oversized filter that matches the operating pressures of the W712/43 the W940/24 does but the center is unperforated.

Hence my question.

Many thanks in advance.

You talking holes, louvers or Ecore? Not sure what your definition of "perforated" is. Need to be more specific.

Those are all perforations.

I am talking the difference, in operation, between perforated and not perforated in a SPECIFIC pair of filters....

Yes they are. But you got a photo of this filter with zero "perforations" of any kind (ie, holes, louvers or Ecore) in the center tube?

Oh dear, How sad, Never mind.

Might try to clarify what you're trying to describe. How you've written things in post 10, it sounds like there are no holes, louvers or Ecore type "center" (those are all "perforations" as you said in post 12) or anything in the "centers" ... what's your definition of "centers" in this context?. If you can't describe things very well then people aren't going to know what you're even talking about and can't give any kind of answer.

Somewhere I saw pics of that, but there are perforations on the ends. I think it may have been Whip City Wrencher. It still has holes somewhere.

 

[ZeeOSix]

If you are talking about the "perforations" in the base plate, then the MANN719/12 has them, just like the MANN W719/43. I see no real difference in the base plate "perforations" (ie, commonly know as "holes").

W719/12

W719/43
