The composite construction replaced earlier multi-layer steel designs and requires correct fitment torque sequences to achieve an effective seal. A failing head gasket on these engines typically presents as coolant loss, white exhaust smoke, or oil emulsification - symptoms that worsen rapidly if ignored.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eComposite material construction, as specified for later 3.9 and 4.2 V8 applications\u003c\/li\u003e\n\u003cli\u003eRequires full head bolt replacement and correct torque-to-yield sequence on installation\u003c\/li\u003e\n\u003cli\u003eSupplied as a single gasket - two required per engine, one per cylinder bank\u003c\/li\u003e\n\u003cli\u003eCheck cylinder head for warping before fitting; resurfacing may be required on high-mileage units\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 1 (1989–1998) and Discovery 2 (1998–2004) V8, Range Rover P38 (1995–2002) V8, and Range Rover Classic V8 with 3.9 or 4.2 composite-type engines.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
