Engine rebuild random banjo bolt found

[trunks]

I have all 8 for the turbo and avcs.  Was cleaning up and found a random fine threaded banjo under the engine stand.   It's the same size as the turbo but fine threaded.  The hole is slightly larger as well.

Can someone please help me out?  I'm constantly wrenching but since it's banjo I'm a bit concerned.

I think there are only 7 banjos?  two each for the avcs lines, a banjo in the top of the turbo, and then the two banjo's for the coolant lines.

There's a turbo oil feed on the back of the head too.  I'm dumbfounded by it.  I looked over my Saab this morning hoping it was missing one on the ventilation system but no luck.

 Here's the back of the head, on my 05. The front side of driver's side has the same filtered banjo set up. Are you asking about a Subaru or a Saab, what year car ?

It's a 2006 Spec B.  I recently was working on my 9-5 in the next stall so just thought maybe.

I've read all Subaru banjos are course thread.  Maybe it was just stuck in the engine stand or cherry picker for a few years and finally fell out

If you don't have any obviously open holes in your engine, I would suspect it's an extra from a previous project.
