Bob, a little off topic, a slight tangent. The VW's air-cooled flat
four. Do they make those in diesel or are the WV diesels the water-
cooled inline fours only? I have heard of some of the buses,
transporters, campers and the vanagons having diesels in them, but I
guess they may have just stuffed the front-wheel drive-trains back in
the back of those maybe?

VW started to make diesel engines after they had given up the Beetle
concept. To my knowledge they only made diesels in the "conventional"
4-in-line watercooled formula.
