[Vwdiesel] Do Diesels ever need similar type cleaning?

[B & R Decker]

    My old time VW mechanic was head service writer in the mid 80's for Pete
Lovely VW in Fife WA (the largest VW dealership in the NW at the time). He
always says the VW 1.5 and 1.6 diesel is much more prone to blown head
gaskets and other troubles when used in stop and go city driving than when
it was used in a high mileage situation. He thinks that cold starting is the
hardest thing on the high compression VW diesel when the block and head are
cold and the head bolt tension would be the least. I'm not sure that is a
correct assumption but I know that whenever I go to revive a gas rabbit that
has sat for a long time it is usually a fueling or electrical problem that
caused it demise but with a diesel it is almost always a blown head gasket.
Loren's right if you drive your 1.5 or 1.6 easy with lots of low rpm driving
you will have a carboned up engine.

  I believe it was Scott that found out (got scolded) that if 
you drive your "early" VW diesel too easily though, your valve 
will gunk up on the backsides with carbon deposits.  In other 
words, drive it spriitedly once in a while and enjoy.  :-)
  Our service mgr. alway said the ones that were driven harder 
had less problems and ran better than the easy driven cars.  He 
never knew just why but then they weren't all that old at that 
time either.
