Sump Plug seals the drain aperture at the base of the engine sump, retaining the engine oil and providing the drain point for an oil change.

Removing the plug allows the used oil to drain from the sump; it is refitted with its sealing washer before the engine is refilled. Correct seating of the plug and washer is essential to prevent oil weeping from the sump pan.

Frequently asked questions

What does the sump plug do?

The sump plug seals the drain aperture at the base of the engine sump, holding the engine oil in and providing the drain point for an oil change. Removing it lets the used oil run out before the engine is refilled.

Should the sealing washer be replaced with the sump plug?

The sump plug itself is reusable, but its sealing washer is typically renewed at each oil change. The washer crushes slightly to seal, so reusing an old one is a common cause of a slow oil weep from the sump pan. Make sure the plug seats cleanly.

Which Land Rover engines does this sump plug fit?

This sump plug fits the V8 twin-carburettor, V8 EFI and 200TDi engines used in the Series 2 and 3, Defender, Discovery 1 and Range Rover Classic. It seals the drain point in the engine sump pan on these applications.
