Frequently asked questions

What does the distributor vacuum advance unit do?

The distributor vacuum advance unit adjusts ignition timing in response to inlet manifold vacuum, advancing the spark under light engine load to improve efficiency and smooth running. This Lucas capsule mounts to the side of the distributor body on the 3.5L V8 carburettor petrol engine.

Which engine does this vacuum advance unit fit?

This vacuum advance unit fits the 3.5L V8 twin-carburettor petrol engine on Land Rover Defender up to 2006. It's the Stromberg distributor capsule for carburettor variants 14G/15G/17G and 19G/20G/21G/22G, so check your carb code before ordering.

What are the signs the vacuum advance unit has failed?

A failed vacuum advance unit typically causes poor throttle response, weak fuel economy and rough running under light load, as the spark no longer advances correctly. A split diaphragm in the capsule is the usual failure, which can also draw a vacuum leak on the V8 distributor.
