I posted a pic of mine in one of my threads (pressure relief valve falls out during oil change (or something like that)). You have already confirmed it's not in the oil pump which is good news.

Good day!!

My internet is acting like dial-up today, but I finally got to that thread you posted at the end of March... I only saw a picture of the oil pump... However, this is the spring I found inside my oil pump... Now, keep in mind I pulled the pump when the engine was on the stand... And I put the pump on the floor in the garage with it "upside down" as in relation to how it's positioned in a running motor... I'm surprised more debris didn't get in there... Food for thought!!! Keep the cap on when storing!!



I'm guessing this is where it goes...



Ideally, this is also the part that I took off that seemed like things weren't quite right... Like the threads (where the dark center plastic piece threads into) got buggered up somehow, but was still used... This was made in Italy... This should come out and is actually part #2 in the picture from your post... Part #1 is only $93... I may get one if I can't find a good used part... I'll inquire about that today...



That part is also where the spring came from (I'M GUESSING!) as there wasn't anywhere else it would look right... There is another spring under this one that keeps a valve closed... Not positive what that is for, but I'm going to guess it is for pressure relief if the filter becomes so clogged that oil can't pass thru it...

Let me know if this helped... I'll take more pictures if needed...

Cheers!!

UPDATE!!! The Realoem filter housing price is seriously outdated... #1 in the picture above is no longer $92.03... It now has an MSRP of $310.23... I'll be sticking with the one I have...
