  If you said "Power Booster Pressure Switch" I might guess there was some sort of
  pressure switch on the brake booster servo. I am not familier with this switch -
  but you may in fact have a leaky one. Unfortunately there are lots of places for
  hydraulic oil to leak from, and most of them are not much fun to repair.
  The type of oil is also quite important. Mineral Hydraulic oil is correct.

  Best thing to do IMHO is to give the whole engine bay and engine a good cleaning
  and start tracing the leaks.
  If you use a pressure washer (as I always do) be careful around the distributor
  bases because they are vented and water can get in, and around the idle/WOT
  switch at the front of the motor. Many have reported water in the connector that
  has caused a problem for them.

  If you still have the belly pan installed, it tends to make leak troubleshooting
  very hard. You may want to take it off for a while. Would'nt hurt to hose it off
  too. Don't leave it off too long though if it is raining a lot. This cover helps
  protect the alternator.
