2016 Land Rover Range Rover Sport 3.0L Diesel · RF66 NFM

The most recent MOT test on 2025-11-01 returned a clean pass, with the vehicle’s overall roadworthiness confirmed as compliant with current standards. However, the persistent oil leak advisory from three consecutive MOTs—recorded in 2023, 2024, and 2025—indicates a recurring issue that requires careful attention. While the leak is not deemed excessive, its recurrence suggests a potential underlying mechanical fault, such as a failing oil seal, gasket failure, or a worn piston ring in the engine, which could escalate into a more serious oil consumption problem over time. The absence of any other failures or advisories in the latest test suggests that the owner has managed to mitigate the immediate risk of roadworthiness failure, but the oil leak must be addressed promptly to prevent accelerated wear on critical components like the cylinder head gasket or camshaft bearings. A thorough inspection of the oil pan gasket, valve cover gasket, and oil filter housing gasket is essential, along with checking for oil contamination in the coolant or fuel systems, which could indicate a more severe internal engine issue. The vehicle’s recorded mileage of 112,810 miles on a 2016 model represents a moderate annual usage rate of approximately 11,281 miles per year, which is consistent with typical long-term ownership patterns for this age and class of SUV. This level of mileage is not unusually high for a ten-year-old Range Rover Sport, particularly if the vehicle has been used primarily for family road trips, commuting, or light off-road driving rather than high-performance or heavy-duty use. However, the absence of significant mileage gaps—suggesting prolonged periods of inactivity—could contribute to other wear and tear issues, such as standing corrosion in the brake systems, suspension components, or undercarriage. For instance, brake discs and pads may show signs of corrosion or binding if left unused for extended periods, and suspension bushes or coil springs could stiffen or develop clunks due to lack of movement. The annual mileage also implies that consumables like fluids, filters, and tyres may have been replaced at a regular interval, but this does not eliminate the need for a comprehensive inspection of age-related wear, such as tyre sidewall cracking or the potential for internal fluid degradation in the engine or transmission. Given the recurring oil leak advisory, the prospective buyer should prioritise a detailed mechanical inspection by a qualified Land Rover specialist or a qualified independent engineer. Focus on the oil pan, valve cover, and oil filter housing for signs of gasket failure or cracks, and verify the oil level and condition during the next oil change—any dark, gritty, or milky oil suggests internal contamination that warrants immediate attention. On a test drive, listen for unusual engine noises such as knocking, ticking, or a loss of power, which could indicate piston ring or valve train issues. Additionally, check for oil leaks under the vehicle, particularly around the front and rear of the engine bay, and inspect the oil filter for signs of bypass flow or excessive oil flow past the filter element. If the oil leak is confirmed to be minor and the engine appears to be in good condition, the buyer should schedule a service within the next 1,000 miles or 6 months, whichever comes first, to replace the suspected faulty gasket and perform a full oil change with fresh, high-quality synthetic oil suitable for the Range Rover Sport’s specifications. For the broader roadworthiness assessment, the buyer should also conduct a thorough inspection of the vehicle’s age-related wear and tear. Given the vehicle’s age and the recorded mileage, the tyres should be checked for sidewall cracking or perishing, which can occur even at moderate mileages due to prolonged exposure to UV light and temperature fluctuations. The tyres should also be evaluated for tread depth and signs of uneven wear, which could indicate alignment or suspension issues that may have developed over time. Inspect the brake system for corrosion on the discs, particularly if the vehicle has been stored for extended periods, and check for binding calipers or uneven braking pressure, which could lead to reduced braking performance or premature pad wear. The battery should be tested for voltage and capacity, as older vehicles are more susceptible to weak or failing batteries, especially if the vehicle has been left unused for prolonged periods. Finally, the fluids—coolant, brake fluid, and transmission fluid—should be checked for age-related degradation, with a recommendation to replace them according to the manufacturer’s guidelines, typically every 60,000 to 100,000 miles or every 5 to 10 years, whichever comes first, to maintain optimal performance and prevent catastrophic failure. Additionally, the suspension, exhaust system, and steering components should be visually inspected for signs of wear, corrosion, or damage, as these areas are particularly prone to deterioration in a high-mileage vehicle.
