Oil Anti-Drainback Valve?

[Braga_Dub]

Did I miss something? None of my filters seem to have that orange thingie in the middle.
Is this something ALH's don't use? Especially since the rod that goes through the filter sticks out on the other side.

Just confused...

I get my oil change kits from impex if that matters.

Are you sure they don't have them? Post a pic of one of your filters.

Yup!
Here is a pic from the top side. (Sorry, cell phone pic...)

Its a Mahle OX 143 D Micro Star...
But so far none of the MANN or Mahle ones I have gotten have had the orange thing in the middle. The one or two OEM ones have also not had the orange thing. All have been like this one, where you can see right through the middle.

I haven't seen anything orange in mine, but all have had the anti-drainback feature. This was the factory installed filter on my passat.

That's because our cars uses a replacement element style filter. The dam in the lower portion of the filter acts as the anti-drainback mechanism

If you had a MKIII TDI or any other car that uses the usual filter can, then you would see an "anti-drainback" valve on the better filters.
