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.
