Strange extra bit under the hood

[Bearskinrug]

Just did my first oil change and after taking off the engine cover I found a small white rubbery thing sitting on top of the engine. Anyone have an idea what it is?

I think I remember someone posting the same thing last year. Other that that I have no idea.

Also, I am like a deer with no eyes!

That is the one I remember.
Does not look the same does it.

Sorry...

Looks like a pen top. Bolt marker, I dunno.
No recall yet

Put it in your kitchen drawer, that way you will never need it.

I have parts from a 1969 SAAB 96 and BMW 1602 in their. I have not needed them yet.

It looks like a cap that goes on a fuel filter in transit to prevent foreign material getting in.
