[Vwdiesel] Blow-by * Additives and Flus

[Chuck Carnohan]

Roger- I have a 1.6 that the block breather is covered with a solid
plate- no hose of any kind and it has the same vacuum pump as in the pic
you provided below without the breather pipe outlet/inlet.  This is on
my mystery "Green Striped" engine.  Any comments?

Usually right next the the oil filter flange:

(1.9D block/breather pictured)

Normally on the 1.6 blocks, the vacuum pump exhaust line is plumbed into
it.  I had trouble on mine with intermittent blowby over-pressuring the
pump and blowing out the plastic check valves randomly.  Adding a tee
fitting and running a line to the VC breather line cured that.
