i'm slowly trying to replace all the bits that leak oil on my knackered old 406, it seems like a battle i can never win, but i shall persevere none the less!!
I need to buy one of the little round things that connects the oil filler breather pipe to the air intake pipe, but i have no idea what its actualy called, and i dont want to find myself in the classic parts desk 'guess the part i'm badly describing' charades conversation, you know the one; "yeah, its erm... you know, the little round bit, black, made of plastic".
So if anyone can tell me, i'd apprecieate it, i've included photos below.
