[Vwdiesel] Diesel Head problems 1.5L NA and more.

[LBaird119 at aol.com]

  My Rabbit's original head had a couple of the cracks open up to easily over
1mm.  It still ran fine but I suspected the slightest bit of gasses seeping
into
the coolant but not enough to really verify for sure.  I changed heads partly
because of this suspicion but mostly because it was easier to build and
modify one then just swap it on.  :)  I still have the old head and consider
it as good.  I've only run across one that had a problem and it leaked
coolant into the exhaust so fast you couldn't fill the radiator.  It was a
nearly new head too.  :(  Got REALLY overheated.
  Most cracks are stress relief.  Either not enough metal, sharp/non
radiused edges or both typically.
