Frequently asked questions

What is the Exhaust Valve (STC1122) for the 3.5 V8?

The STC1122 is a cylinder head exhaust valve for the Rover-derived 3.5 V8 petrol engine. It seals the exhaust port and opens to release burnt gases from the combustion chamber.

Which Land Rover models use this 3.5 V8 exhaust valve?

This exhaust valve fits the 3.5 V8 in the Defender 90/110 (up to VIN LA921745), Discovery 1, Range Rover Classic, and Series III. All are the 3.5-litre V8 petrol.

How many exhaust valves are needed for a full 3.5 V8 job?

The 3.5 V8 typically has eight exhaust valves, one per cylinder, and this valve is sold individually. Order eight for a complete set, or the quantity your cylinder head rebuild requires.

Is 614089 the same as this exhaust valve?

614089 is a listed alternative code for STC1122, so it refers to the same 3.5 V8 exhaust valve. You can order under either reference for this application.

What are the signs a 3.5 V8 exhaust valve needs replacing?

A worn or burnt exhaust valve usually causes loss of compression, misfire, and poor running on the 3.5 V8. Valves are typically replaced during a cylinder head overhaul or when a valve seat fails.
