[AGL] BMW boxer twin

[Jon Ford]

Mike--
I heartily agree about the advantages of water cooling. I've had some VWs 
seize up on me, never had this problem with water cooled. I've owned about 
10 VWs and a couple of Porsche's. Another problem with the engines is that 
the bolts holding the cylinders together tend to pull out at high 
heat/speed, ruining the engine. At least this has been my experience. I once 
spent three or four days of my vacation in a cheap Motel in Ponca City, 
Oklahoma waiting for the local yokels to rebuild my Volkswagon bug , which 
admittedly was an older one with a rebuilt engine in it.
