{"product_id":"piston-ring-set-20-tdv6","title":"Piston Ring Set +20 TDV6 for Discovery 3 (2005 – 2009) +0.02 Inch – E274103","description":"\u003cp\u003eThis piston ring set is machined to a +0.02 inch (0.50mm) oversize specification for use during engine rebuilds on the 2.7 TDV6 diesel engine, where standard-bore pistons are no longer viable due to cylinder wear. The ring set seals combustion pressure, controls oil consumption, and transfers heat from the piston to the cylinder wall - functions that degrade when rings wear, leading to blow-by, excessive oil burning, and power loss. Using the correct oversize specification is critical to achieving proper ring-to-bore clearance after cylinder honing or reboring.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e+0.02 inch (approximately 0.50mm) oversize - intended for use with rebored or honed cylinders at this specific diameter\u003c\/li\u003e\n\u003cli\u003eFull set covering all rings per piston; confirm quantity required against number of cylinders being rebuilt\u003c\/li\u003e\n\u003cli\u003eDesigned for the 2.7 litre TDV6 diesel engine shared across Land Rover and Jaguar platforms\u003c\/li\u003e\n\u003cli\u003eReplace piston ring sets in conjunction with checking bore condition, piston clearance, and bearing wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits the 2.7 TDV6 diesel engine as found in the Discovery 3 (2005–2009), Discovery 4 (2010–2016), Range Rover Sport (2005–2009), Jaguar S-Type, XJ (2003–2009), and XF (2009–2015).\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
