What is an Oil Pressure Screen?

Published in Engine Oil System Component 2 mins read

An oil pressure screen is a small filtering component found in some engine oil systems.

Understanding Oil Pressure Screens

Based on the provided reference, an oil pressure screen serves as a filter within an engine's lubrication system. Its primary role is to capture smaller debris that might be circulating in the engine oil before it reaches critical components.

Here's a breakdown of what the reference tells us about these screens:

  • Size and Shape: They are described as small cylinders, roughly the size of a mini can of Coke.
  • Function: Their purpose is to filter out the smaller stuff from the engine oil. This helps prevent particles from clogging narrow passages or damaging sensitive parts.
  • Accessibility and Maintenance:
    • They are removable on all engines in which they are installed. This makes them accessible for service.
    • Maintenance involves a specific process:
      • Cleaning: They are cleaned with mineral spirits.
      • Inspection: They are inspected for damage or blockages.
      • Reinstallation: They are then reinstalled.
    • Maintenance Frequency: This cleaning, inspection, and reinstallation process is performed as part of every oil change.

In essence, the oil pressure screen acts as a crucial line of defense, ensuring the engine's oil remains cleaner and flows properly to maintain optimal pressure and lubrication. Regular service of this screen is essential for the longevity and performance of engines where it is installed.
