	I've read it allot.  I don't know where the truth is.  From what
	I can tell, these guys were the contrarians.  At the time, though,
	they knew more about VW diesels than anyone else.  

	It's interesting that some Chinese Diesel manufacturers tout
	that their lower bearings are "made by VW", apparently 
	trying to piggyback on the reputation of the VWs.  Gee, I
	should go look at the spare parts kits for the last round of
	Chinese diesel generators, and see if I can see any VW 
	markings on the bearings.  Hold your breath on this one...

	I can say that the industrial 1.488 diesel sure looks like the
	1.5 NA.  Oh, another difference.  The Bosch injector pumps 
	were configured so that the "throttle position" was really 
	an RPM setting.  I'm sure it was a different injector pump,
	although it looked the same.
