Range Rover 5.0 Engine for Sale | OEM Used Jaguar

Jaguar / Land Rover 5.0L V8 from the modernized AJ-V8 family. The Range Rover 5.0 engine is the OEM Jaguar / Land Rover AJ-V8 508PN 5.0L V8 engine, introduced in 2009 succeeding the earlier AJ-V8 4.4L / 4.2L variants. The AJ-V8 508PN serves as the premium V8 engine across the Jaguar / Land Rover lineup including Range Rover L322 (late) / L405, Range Rover Sport L320 (late) / L494, Land Rover Discovery 4 / LR4, and Jaguar XF / XK / F-Type applications. With output ranging from 375 HP (naturally-aspirated) to 510-550 HP (supercharged depending on application generation), the AJ-V8 508PN represents Jaguar / Land Rover's flagship V8 performance from approximately 2009 through the mid-2010s. Specifications: 5.0 liters displacement, 90-degree V8, aluminum DOHC 32-valve, direct injection (GDI), variable cam timing, timing chain driven.

Naturally-aspirated 375 HP vs supercharged 510-550 HP with substantial differences. The AJ-V8 508PN NA (Naturally-Aspirated): 375 HP at 6,500 RPM, 375 lb-ft torque, naturally-aspirated configuration without supercharger. Used in Range Rover HSE / Vogue, Range Rover Sport HSE, Land Rover Discovery 4 / LR4 HSE applications. The AJ-V8 508PS Supercharged: 510-550 HP, 461-502 lb-ft torque, Eaton TVS R1900 twin-vortices supercharger with intercooler. Used in Range Rover Supercharged / Autobiography, Range Rover Sport Supercharged / SVR (550 HP), Jaguar XKR / XJR / F-Type R applications. The NA and supercharged variants share the same basic AJ-V8 508 architecture but differ substantially: the supercharged variant adds the Eaton TVS R1900 supercharger, intercooler, revised pistons (lower compression ratio), reinforced internals, upgraded fuel system, and modified ECU. Cross-application between NA and supercharged variants is NOT recommended without major modification.

Multiple Range Rover / Land Rover / Jaguar applications. Range Rover L322 (late, 2010-2012): AJ-V8 508PN replaced the earlier 4.4L AJ-V8 for L322's final years. Range Rover L405 (2013-2021): fourth-generation Range Rover, AJ-V8 508PN throughout production (NA and Supercharged variants). Range Rover Sport L320 (late, 2010-2013): AJ-V8 508PN replaced the earlier 4.4L for L320's final years. Range Rover Sport L494 (2014-2022): second-generation Range Rover Sport, AJ-V8 508PN throughout production including SVR variant (550 HP supercharged). Land Rover Discovery 4 / LR4 (2010-2017): AJ-V8 508PN NA variant in LR4 HSE LUX trim. Jaguar XF / XK / F-Type: various Jaguar applications use the same AJ-V8 508PN engine. Cross-application between these chassis requires careful ECU, accessory, and engine mount verification.

Modern AJ-V8 vs classic Jaguar V12. The Jaguar / Land Rover AJ-V8 508PN 5.0L V8 (this listing) is the modernized Jaguar / Land Rover V8 engine from the AJ-V8 family. The Jaguar V12 engine is the classic Jaguar V12 5.3L / 5.3L HE / 6.0L V12 engines spanning multiple generations of Jaguar V12 production from the 1970s through 1990s (the historical predecessor V12 architecture from Jaguar's classic V12 era). The Jaguar V12 represents Jaguar's V12 heritage (smooth, refined high-displacement V12 engineering), while the AJ-V8 508PN represents the modern Jaguar / Land Rover V8 engineering (forced-induction performance and direct injection). Two British luxury engine listings across : (this listing) AJ-V8 508PN 5.0L V8 for modern Range Rover / Range Rover Sport / Discovery / Jaguar XF / XK / F-Type applications, Jaguar V12 5.3L / 5.3L HE / 6.0L for classic Jaguar V12 applications.

Eight well-documented failure modes. Timing chain wear: AJ-V8 timing chain stretch and tensioner wear is well-documented; chain stretch can cause cam timing issues and check engine codes; replacement requires engine-out labor. Cooling system / thermostat failures: the AJ-V8 has documented thermostat failures and cooling system issues; thermostat replacement is a common maintenance item. Coolant crossover pipe / pump: coolant crossover pipe and water pump are documented wear items. Supercharger nose bearing wear (supercharged variant only): Eaton TVS R1900 supercharger nose bearing can fail at high mileage. Direct injection HPDI fuel pump cam follower wear: standard direct-injection wear pattern. Carbon buildup on intake valves: direct injection inherent wear pattern requiring walnut shell blasting every 60,000-100,000 miles. Valve cover gasket leaks: common with age. Variable valve timing solenoid wear: solenoids can fail causing VVT codes.

Timing chain inspection, cooling system, carbon cleaning, supercharger service (supercharged variant). After acquiring a used AJ-V8 508PN engine, budget for these items. Timing chain inspection: budget $300-500 for inspection (replacement only if chain stretch is detected, typically $3,000-5,000 if needed due to engine-out labor on AJ-V8). Cooling system service: $500-1,000 for thermostat, coolant crossover pipe, and water pump preventive replacement (documented AJ-V8 wear pattern). Carbon cleaning service: $600-1,200 for walnut shell blasting on intake valves (recommended every 60,000-100,000 miles for direct injection). Supercharger service (supercharged variant only): $200-500 for supercharger oil service if not done recently. Strict synthetic oil maintenance: 5,000-7,500 mile intervals with Jaguar / Land Rover-approved premium synthetic oil. Specialty British marque support team familiarity recommended.

Reliable when properly maintained but specialty maintenance required. The AJ-V8 508PN is generally regarded as a competent modern V8 engine with strong performance, but specialty British marque maintenance is required to maintain reliability. The documented concerns (timing chain wear, cooling system / thermostat failures, supercharger nose bearing wear on supercharged variant) require specialty Jaguar / Land Rover technician attention rather than generic shop maintenance. When properly maintained at a qualified Jaguar / Land Rover specialist with proper synthetic oil intervals (5,000-7,500 miles), proactive cooling system maintenance, and timing chain inspection at 80,000-100,000 miles, the AJ-V8 can deliver 150,000-200,000 plus miles of reliable service. Neglected maintenance accelerates the documented failure patterns. Budget for specialty maintenance accordingly.
