Please identify this gasket

I found this Parker gasket stuck to the bottom of my oil drain pan after replacing the stock triumph oil filter with the KN version.  Dealer did the last oil change.  I can't recall seeing this gasket before and if it was installed on the triumph oil filter it would block the drain holes.  I feel foolish asking but where was this from and do i need to reinstall?

How about a picture of the other side too?

I wouldn't sweat it, but I have world of triumph and the service manual open trying to find what the hell it is for

My guess is if you shot the picture to the shop mechanic he'd probably tell you it was something from another job.

I am starting to really hate my aging brain which i was racking trying to figure out what else oil and filter related I did recently.  I finally remembered that only last week i cut open a filter from my old mustang to see if there was anything nasty in there.  This gasket is probably from the inside of a motorcraft fl1 a filter and it fell in the pan when I cut it open. 
Sorry to waste everyone's time.

Thanks for checking.   That was my concern regarding the mechanic but I think this is operator error!   See above

Yep, it's the anti-drainback valve from the filter you cut open.

If you google your filter part number and "cut open" and choose images....I think you nailed it!


Ps.....i too have CRS syndrome

 I did Google the part number but not cut open.
This is just sad.  Crs has taken full hold of me.
