Oil Pressure Switch for the Rover V8 engine lubrication circuit.

The switch threads into the engine oil gallery and closes below its set pressure threshold, driving the low oil pressure warning lamp in the instrument circuit. It is used on the 3.5L carburettor and 4.0L EFi V8 petrol engines; it is not a diesel-engine part.

Replace when the warning lamp remains lit with oil pressure confirmed good, or when the switch body weeps oil.

Frequently asked questions

What does the STC4104INTBM oil pressure switch do?
The STC4104INTBM oil pressure switch senses engine oil pressure and drives the dashboard oil pressure warning light on V8 petrol Land Rovers. It threads into the engine block or oil filter housing and typically triggers the warning lamp when pressure drops below a safe level.
Which Land Rovers does this oil pressure switch fit?
This oil pressure switch fits V8 petrol engines only, not diesel. It covers the Defender up to 2016 (3.5 Twin Carb and 4.0 EFI), Discovery 1, Discovery 2 V8, Range Rover Classic and Range Rover P38 4.0 and 4.6 V8 EFI. Confirm your engine is petrol before ordering.
Why does an oil pressure switch fail on a V8 Land Rover?
Oil pressure switches typically fail when the internal diaphragm leaks or the contacts corrode, causing a false low-oil warning light or an oil weep at the switch body. It's a common cause of an intermittent oil pressure lamp on these V8 engines.
