Frequently asked questions

What is the Distributor O-Ring (603446) and what does it do?

The distributor O-ring seals the ignition distributor where its base locates into the engine, preventing oil leakage at the distributor mounting. It fits the 3.5L V8 petrol engine used in models such as the Range Rover Classic, Discovery 1 and Land Rover Series.

Where does this O-ring fit on the V8 engine?

This O-ring fits around the base of the ignition distributor on the 3.5L V8 petrol engine, sealing the joint where the distributor enters the engine. It's a common source of an oil leak at the distributor on the Range Rover Classic and Discovery 1 if the seal hardens.

Can the distributor O-ring be reused?

The distributor O-ring is typically a single-use seal, so it's best to fit a new one whenever the distributor is removed from the 3.5L V8. Reusing an old, compressed O-ring usually leads to an oil leak at the distributor base soon after refitting.
