The ring set restores compression, controls oil consumption, and maintains the correct combustion seal between the piston and cylinder wall. Fitting incorrect ring sizes on a rebored engine will result in poor sealing, excessive blow-by, and accelerated wear.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e+0.020 inch (0.508mm) oversize - intended for use with a correspondingly rebored cylinder bore\u003c\/li\u003e\n\u003cli\u003eSingle cylinder set - order one set per cylinder, four sets required for a full engine rebuild\u003c\/li\u003e\n\u003cli\u003eDesigned to OEM specification for the Land Rover 300Tdi engine\u003c\/li\u003e\n\u003cli\u003eCheck bore diameter with a micrometer before ordering to confirm the correct oversize grade is required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Land Rover Defender (1986–2006), Discovery 1 (1989–1998), and Range Rover Classic, all fitted with the 300Tdi engine.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
