I own a bus (although it now resides in my father's pasture), and that thing was on the floor at all times, except when there was a red light or stop sign immediately ahead. At the risk of getting off topic, I doubt that oil causes dropped valves. Having been a "factory" VW mechanic in Las Vegas, I can tell you that most VW engine valve failures (especially in buses) happen after a long hill climb on a hot day, which weakens the connection between valve stem and its welded head due to prolonged high temperatures, and then you come over the hill and let off the gas and the valve head gets pulled off the stem by the high vacuum....and then you have a three cylinder engine, and your bus gets added to the line at the VW dealership with all the rest of the buses that await the mechanics on Monday morning, and you end up with what you describe. Just like clockwork. This doesn't happen on VW airplane engines due to the lack of high vacuum after a climb, and our habit of using one piece stainless valves, which is why you don't usually hear of this kind of failure in our useage.
