{"product_id":"tappet-kit-cylinder-head","title":"Tappet Kit - Cylinder Head for Defender (1986 – 2006) Engine valve - Hydraulic – RTC6564","description":"\u003cp\u003eRTC6564 is a tappet kit containing hydraulic valve lifters for the cylinder head, used in Land Rover's four-cylinder diesel and petrol engines fitted to the Defender and related models. Hydraulic tappets automatically compensate for valve clearance changes as the engine heats and cools, eliminating the need for manual adjustment. Worn or collapsed hydraulic tappets produce a characteristic ticking noise at startup and can cause reduced valve lift, leading to loss of compression and performance.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eHydraulic tappet design providing automatic valve lash compensation without manual adjustment\u003c\/li\u003e\n\u003cli\u003eKit format supplies the full set of tappets required for a complete cylinder head rebuild or replacement\u003c\/li\u003e\n\u003cli\u003eManufactured to OEM specification, compatible with Land Rover part number RTC6564\u003c\/li\u003e\n\u003cli\u003eWhen fitting, inspect camshaft lobes for wear and replace engine oil and filter to prevent debris contaminating new tappets\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Land Rover Defender (1986–2006) with 2.5 Diesel NA, 2.5 Petrol, 2.5 Turbo Diesel, 200Tdi, and 300Tdi engines; Discovery 1 (1989–1998) with 200Tdi and 300Tdi engines; and Range Rover Classic with 200Tdi and 300Tdi engines.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
