Oil Filter threads

[spasm3]

Before i install a new filter i wipe the threads by spinning the filter while holding a cloth or towel against the threads. I usually get a gray result on the towel , somtimes a few small bits of metal show up. I do make sure there is no lint on the threads aftewards before filling it and spinning it on.
I've seen this on motorcraft filters Mobil 1 filters, just about any filter i've used.
Anyone else notice this?

I do that very exact same thing :^)

We have discussed this before. Around here Purolaters are by far the worst for this. Guess who has the least amount of scrap metal around their threads?

I had that happen the last time I changed my oil. I still lose sleep over it ever now and then. Im not sure I got all the shavings off and think one might have fallen through the threaded hole. I shook it around upside down but couldn't tell if anything came out. I had already removed the old filter and drained the oil so I was kind of SOL. I guess I will see in the oil analysis report if it did anything. Or if a shaving even went through at all. It's time to change it again so I guess I'll find out.

I've never thought to wipe the threads. I do lube the seal with a wipe of new oil, though. After reading these posts I will be using a lint free cloth to wipe it first, going forward though.

Vacuum cleaner on the center hole will suck out any loose shavings inside the center tube.

I like the shop vac idea

That's some crazy [censored].....I don't have much experience with other filters (only ever used FRAM XG/TGs....or ST) but never noticed this.....

I'd think this would be an issue that needs to be raised to hte filter manufacturers, they need to add a filter clean out process (shop vac type, or even [censored] loads of air blown into the filter (though that might mess with the filter media....I suppose?) but the shop vac idea would probably better off....

Works good ... only a real BITOG manic would think of this.

I've never noticed metal on Donaldson, but the brown or gray can be the anti-corrosive they put on the steel so it won't rust.

Another idea is giving it a blast of canned air. Never envisioned doing this before, but I prefer to install a new filter free of metal shavings and debris, and if that's what it takes...

So metal on the threads is good?

Here is a video clip showing the manufacturing of a Fram filter. As you can see, they thread the "capping plate" using a conventional tapping die. It isn't surprising that you will get some shavings on occasion. And I don't see any step that wipes the threads!

I once found metal slivers around the threads of an Mobil 1 filter. I called Champ Labs and they said that they use a high pressure wash to clean the threads and plate before it is assembled onto the can. They requested the batch number, etc. I guess it depends on their quality control. I always wipe mine with a paper shop towel to remove any residue.
