Hello,
I fitted a used BSH catch can on the weekend and one of the covers on the this part was missing:-

I've made a makeshift cover but it blew off gives me a rough idle etc.
So where can I get a cover like the other 2 pictures, or even so help with whats it called so I can look on ebay, I typed in nipple cover and had some interesting items come back ....

Cheers,
Rob
