hi, your information is correct regarding the ford part. VW also do it on it's own under a sharan part number ( I think ). there's a list of part numbers stickied in the dub chat forum. alternativly plug the hole in the intact pipe and vent the cam cover to a can, red bull seems to be the beverage of choice ;-) plug and play. you may need a jubilee clip to attach it to the cam cover.
