All engine parameters should be kept in operational limits, stated by the Maker.

High lubricating oil pressure may indicate:

  1. A clogged filter, if pressure measuring point located between the filter and LO pump
  2. Closed valve(s) in the line
  3. A clogged LO cooler
  4. A faulty pressure regulating valve of the LO pump
