{"product_id":"bolt-cylinder-head-183579","title":"Bolt - Cylinder Head for Discovery 1 (1989 – 1998) Long – 602193","description":"\u003cp\u003eThis is a long-pattern cylinder head bolt designed for the Rover V8 engine as fitted to Land Rover Discovery 1, Range Rover Classic, and Series 3 models. Cylinder head bolts clamp the head to the block, maintaining the head gasket seal under the thermal and mechanical stress of combustion; stretched or fatigued bolts are a leading cause of head gasket failure on the Rover V8. Using the correct long bolt variant is essential, as mixing long and short bolts results in incorrect clamping torque and potential gasket failure.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eLong-pattern cylinder head bolt, matched to the specific block deck depth of the Rover V8\u003c\/li\u003e\n\u003cli\u003eMust be torqued to the manufacturer's specification in the correct sequence to ensure even head gasket loading\u003c\/li\u003e\n\u003cli\u003eSuitable for both 3.5 and 3.9 V8 petrol engine variants\u003c\/li\u003e\n\u003cli\u003eCylinder head bolts should be replaced whenever the head is removed - reusing stretched bolts risks incorrect clamping force\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 1 (1989–1998) 3.5 and 3.9 V8 Petrol, Range Rover Classic 3.5 V8 Petrol, and Series 3 3.5 V8 Petrol (long bolt applications).\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
