OM364LA mystery filler cap

[mycophagist]

G'day brain trust.

I've recently purchased a mercedes bus with an om364la, and im having trouble identifying and tracking down what looks like a filler cap that goes on to the timing end cover.

I'm hoping that someone here will maybe be able to suggest some more accurate keywords for me to use when searching, because I just can't seem to track it down.

Thanks heaps, in advance : )

It is just a breather, and used to see the timing marks when setting up the fuel pump, not a filler cap, basically any cap that fits will do, there is no pressure behind it, if you know someone with a 3D printer, they could make one for you out of TPU in a few minutes
