Back in the early 80s I am sure VW thought that these motors were great and that adding water cooling would be fairly simple seeing how they could steal parts from the now proven Diesel engine. They didn't drive them for 250.000kms to find out that the heads would leak and really, what car manufacturer wants something to last that long - VW really wishes our vans would die so we would buy new ones right? Look at the Beetle er um Porsche 911 today... flat six and water cooled. Many people will argue that the sole left the 911 a long time ago, but this is the true evolution of the boxer engine. The only great air-cooled boxer remaining today is the BMW R1200 series and technically these are oil cooled engines... the last air head was in the mid 90s.
