Searched the site, and google, and haven't found much. Installing a new cylinder head, and stuck on how one part (actually two of them) is installed back in the car. They are two plastic pieces that sit over the cams. I know that they go there, because I remember seeing them inside every time I replaced the oil. The part number 058 103 555 b. I have found on google that it is a deflector of some sort? Any assistance on how to install these would be greatly appreciated.
