well............
I sure can't think of many parts from vw's diesel engine that go on a
waterboxer engine....
not one part actually.
Do you have first hand information that they did NOT test the waterboxer
engine extensively ?
and 'proven' diesel engine ......? .....perhaps in Rabbits.
but in Vanagons - nein.
or.......sure, 'proven' for about 80,000 or so miles.......after that
you're on borrowed time.......on a stock 1.6NA 48 hp diesel vanagon engine.
I don't know about back then, but these days I read about all kinds of
extensive real world testing of new models......from desert to arctic
conditions. You'd think VW would do some of that if coming out with a whole
basically new engine and cooling system for vanagons.
speaking of water-cooled 'waterboxer' engined Porsches......
my understanding is that Porsche did their first did their liquid cooled, 4
valves per cylinder 6 engine with the Boxster ......
and...........that that engine as a common problem with coolant getting into
the oil I think.........something like that,
and that there really isn't a viable repair.
I guess we'll have to say that tdi engines and 2.1 waterboxer engines are
oil cooled too, since they have oil coolers.
Does your R1200 have a radiator with anti-frz in it or not ?
but we do love 'em, that's for sure.

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.
