  So now we have to be "qualified" to state our opinions or 
observations on this list?  Geez...
  It was a standard "knowlege" when I worked at the dealer.  Also 
Scott Kair encountered the same "standard knowlege" when he 
had one worked on and the guy then showed him the buildup on 
his intake valves and the restriction it was causing.  Not to say 
everyone knows it or proves it but 20 years ago when a lot of 
these little engines were running around, the knowlegeable people 
I met all had the same consensus on driving them easy vs hard.
  Actually on a diesel intake valve there's not a lot of place to get 
deposits on the valve, oil and fuel either kicking back in the overlap 
or coming in from the breather or past the guides.  To clear it off 
there's 3 ways, high velocity air going past them (winding the engine 
out) mechanical removal (head disassembly and cleaning) or solvents 
which usually entail special machines and solvent which Scott and I 
kicked around the idea of where he worked, getting one.  Snap-on 
sells them and they ain't cheap.
  To say that driving it below 55mph will make it last forever is a much 
less proveable point.  Distance at each start, oil used, air cleaner 
quality and initial ring quality (I've seen Audi and Volvo diesels that 
make me bring this up) and proper oil levels and change intervals as 
well as coolant maintenance have a LOT more to do with engine 
life than the speed it's driven. Heck, my Rabbit will run at 55mph all 
day in 3rd instead of 5th.  It would definitely shorten the life if I drove 

it that way more than just to top the pass.  Vanagons basically do 
that same thing and the engine life is much shorter.
