🔌 Function

The filter removes abrasive particles, rust, gum and other contamination from the fluid stream before it reaches sensitive engine components. Correct filtration protects bearings, oil galleries, injectors, fuel pumps, carburettor passages and precision control valves from restriction and wear.

Common signs of failure:

• Engine oil leaks from beneath the spool-valve housing

• VTEC or oil-pressure fault codes occur after oil level and pressure are confirmed

• Screen is restricted by sludge or metallic debris

• Gasket is flattened, split or hardened

• Spool valve has been removed and the sealing gasket requires renewal
