{"product_id":"gasket-188544","title":"Gasket (Engine) for Discovery 3 (2005 – 2009) Upper – LJQ500020","description":"\u003cp\u003eLJQ500020 is an upper engine gasket designed for the 4.4 AJ-V8 and 4.2 supercharged V8 engines fitted to Land Rover Discovery 3, Range Rover, and Range Rover Sport models. Upper engine gaskets seal critical interfaces within the top end of the engine, preventing oil and coolant ingress into areas such as the cam cover or inlet manifold mating faces. A failed or deteriorated gasket in this location can result in external oil leaks, misfires, or coolant contamination, making accurate like-for-like replacement essential.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned specifically for the upper engine assembly on AJ 4.4 V8 and 4.2 V8 supercharged variants\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement ensuring correct dimensional fit at the upper engine mating face\u003c\/li\u003e\n\u003cli\u003eMatches original Land Rover specification for material and sealing properties\u003c\/li\u003e\n\u003cli\u003eWhen replacing this gasket, inspect adjacent seals and fastener condition before refitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 3 (2005–2009) 4.4 AJ V8, Range Rover (2002–2009) 4.2 V8 Supercharged and 4.4 AJ V8 (to VIN 6A000001), and Range Rover Sport (2005–2009) 4.2 V8 Supercharged and 4.4 AJ V8.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
