Frequently asked questions

What is the Oil Pump Relief Valve Spring used for?
The Oil Pump Relief Valve Spring sets the pressure at which the oil pump's relief valve opens. It holds the valve plunger closed until oil pressure exceeds the calibrated limit, then yields to bleed off excess and cap peak pressure. Fits Land Rover Series 2/3, Defender, Discovery 1 and Range Rover Classic engines.
Why would the oil pump relief valve spring need replacing?
The oil pump relief valve spring can weaken with age, letting the valve open too early and drop oil pressure, or stick and hold pressure too high. Renewing a tired spring during an oil pump overhaul restores correct relief pressure. It's a common item to replace when refreshing the pump.
Which engines does this relief valve spring fit?
This oil pump relief valve spring fits Land Rover Series 2/3, Defender (1987-2006), Discovery 1 200 TDi and Range Rover Classic 200 TDi. Discovery 1 and Range Rover Classic have chassis-number breaks, so check your VIN if you're near a build change. It's also listed under number 265623.
