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.
