Here's one place: http://www.pelicanparts.com/BMW/catalog/shopcart/BE39/POR_BE39_ENGcyl_pg4.htm#item17 Here's another, less than Pelican's listed price - note that from the above, it appears there are two, for up to 9/2002, and after 9/2002. This is for up to 9/2002: http://www.getbmwparts.com/parts/in...2-1-432-928&action=oePartSearch&siteid=214672 $293.60, lowest listed price I could find - autohausaz.com & Bavauto were both at about 348, with autohausaz priced fourteen cents less than Bavauto. Googling "BMW" and the part number brought up several other vendors, again nobody priced as low as getbmwparts. If you have a preferred vendor other than getbmwparts, they might have a price-matching policy.
Thanks for the help. I have to wait for wife to bring it home so I can investigate a bit more...Hard to believe 293.60 for a plastic part!
Why do you need the valve cover? It's a clean and replace item unless something else happened to it. I'd be tempted in sending it out for cleaning and powder coating though. This should be a <$100 job with the oil change that should be done after the gasket is installed and the engine run ever so briefly or during.
