I noticed oil leaking on the top of the engine and found that the "extension" piece that goes from the valve cover up to the top of the plastic upper cover is broken. I was able to retrieve the little metal piece as well as the broken bits of plastic. Anyone know where I can get this piece for my 97 Passat TDI? The part number on the unit is 028 115 301... Also, what is this known as "officially" and any clues on why it broke? Thanks....
