I have always wonder what goes on inside an oil filter. Wow, this is really an amazing little part. Below is a list of things that are inside an oil filter:

  1. TAPPING PLATE inside an oil filter

This serves as the entry and exit point for oil. Small holes around the edge facilitate the free flow of oil into the container. The threaded centre hole is where the oil flows out and how the container attaches to the engine.

2. ANTIDRAINBACK VALVE

Because the oil filter is typically located toward the middle or bottom of an engine, this rubber valve has a flap that blocks oil from draining back into the filter when the engine is off.

3. FILTER MEDIUM

The porous filter medium, which increase filtering efficiency and durability. The medium has resin to give it strength and stiffness. Higher-grade filters have more synthetic fibres.

4. PLEATS

Folding the filter medium creates a greater total surface area. The number of pleats depends on the medium’s thickness.

5. CENTER STEEL TUBE

The centre tube provides structure and allows filtered oil return to the engine. The number, size, and position of the holes is key to ensuring that the oil flow is not restricted.

6. RELIEF VALVE

On a cold start up, oil can be too thick to filter. To prevent the engine from starving, the relief valve opens when the pressure builds enough to force the calibrated spring downward, allowing unfiltered oil into the centre tube through the top.

7. END DISC

To keep unfiltered oil from leaking into the centre tube

8. RETAINER i

A thin bit of metal that acts as a leaf spring, the retainer keeps the filter medium and end disc tight against the tapping plate.
