Gasket below oil breather pipe

Looking for a gasket for this little box thing but don’t know exactly what it’s called?



Anyone able to enlighten me please…

Thanks... should have googled oil breather gasket earlier...

Thanks…does this box looks standard? Additional plate looks like the sort of bodge I would do if it was leaking …

 

Normally it's just a sealed top with a dimple in it. Maybe somebody has cut a hole in it then somebody plated it over? Could it be some strange Californian emissions mod?

 

yeah something else to add to my list of wants ...

 

Possible that it's rusted through at the bottom and someone's patched it.

 

Spoils the look of my new parts though…

 

If it came from a car the oil filler would have been there I think, and FI have a thingy on top too. Someone has repurposed it.
