Mein Auto: 2000 740I sport
when I bought my 740 2000 sport same problem. valve cover gaskets replace all the hoses under the manifold spark plugs as well and the culprit is the OSV valve at the back of the manifold its a bitch but you have to replace all the related parts to get it right and check the O2 sensors they burn up when coated in oil also when you take the intake off tip on end for a while to drain the oil out of it.
