Frequently asked questions

What is the ERR5027 cylinder head used for?
The ERR5027 cylinder head is the upper casting that closes the cylinder block on the 2.5L 300 TDi diesel. It carries the valves, seats and guides, forms the combustion chambers, and seals to the block through the head gasket.
Does this cylinder head come complete or as a bare casting?
It's supplied as a new bare casting, less core plugs. The valves, guides and core plugs typically need transferring from the old head or buying separately. This is the 300 TDi head only, so check whether a reman version suits your build.
Which models and engines does this head fit?
This head fits the 300 TDi Defender and Discovery 1, plus the Range Rover Classic 1992-1994 from VIN JA610294 with the 2.5L 300 TDi. It does not fit 200 TDi engines. Use your VIN to confirm the Range Rover Classic.
Why does a 300 TDi cylinder head need replacing?
A 300 TDi cylinder head typically needs replacing after cracking between the valve seats, warping from overheating, or corrosion in the coolant passages. These are common failure points on high-mileage heads, often found when the head gasket is changed.
