Make sure you have the correct sensors. The sensor by the oil pump should be
a .9 bar. This often gets confused as even some of the Microfiches show a
1.8 bar sensor. Another problem can be corrosion in the wire connections or
a bad wire to the sensor. Check these carefully. I've seen people change
engines for no reason. Last thing would be to check the oil pressure with a
gauge. Should be able to obtain ~10 psi/1000 RPM. Slightly less if the
engine is hot.

  Subject: OIL PRESSURE LIGHT/ALARM

  I have an 87 Synchro Westy with 153,000 miles on it.  I was told the heads
  had been reworked at about 120,000.  I started getting an oil pressure
alarm
  below 3100 rpm after the engine has warmed up.  I replaced both oil
pressure
  sensors, and just finished replacing the oil pump with a high volume pump
  from Bus Depot.  I still got the alarm after then engine warmed up.
Bummer.

  A mechanic friend of mine says that my main bearings are probably worn to
the
  point that there is too much clearance.  About ten years ago I rebuilt a
bug
  engine.  I remember having to have the case line bored.  Of course, this
  required OD bearigs.  Is this common with the 2.1 Wasserboxer?  Has anyone
  out there replaced the main and camshaft bearings without having to rebore
  the case?

  If I do decide to rebuild, what other pitfalls should I look out for?

  Maybe now is the time to look for that Subaru engine.
