Land Rover 508PS Engine Replacement Cost (UK)
Condition | Supply Only | Fitted (Independent Specialist) | Typical Warranty |
|---|---|---|---|
Used | £4,500-£7,000 | £5,540-£8,300 | 3-6 months |
Reconditioned | £8,000-£12,000 | £9,040-£13,300 | 12-24 months |
Rebuilt | £10,000-£14,000 | £11,040-£15,300 | 12-24 months |
The final cost of a Land Rover 508PS engine replacement is heavily influenced by the condition of the supercharger assembly and the timing chain history. Units rebuilt with a new supercharger isolator coupler, updated timing chain tensioners (for pre-2013 blocks), and refreshed oil cooler seals command a slight premium but prevent near-term repeat failures. For a detailed breakdown of how specific component conditions affect the overall Land Rover 508PS engine cost, see our full reconditioned engine cost guide.

Common Problems
Land Rover 508PS Engine Problems - What Actually Fails
Every engine has its weak points. Here are the known issues with the 508PS, based on real-world data and verified failure patterns.
Verified issue focus: Supercharger coupler wear and oil cooler leaks.
1. Supercharger Coupler Wear
1. Supercharger Coupler Wear
Typical onset:
60,000-90,000 miles
What happens:
The plastic isolator coupler located between the supercharger snout and the crankshaft pulley degrades over time. This causes a distinct rattling, knocking, or "marbles in a tin can" noise on startup or under load, and can eventually lead to a loss of boost or supercharger drive failure.
Repair vs replace:
Coupler replacement is a standard, relatively inexpensive maintenance repair and does not require a full Land Rover 508PS engine replacement.
Read more about this issue
2. Oil Cooler Leaks
2. Oil Cooler Leaks
Typical onset:
80,000-120,000 miles
What happens:
The oil cooler seals or the cooler housing itself can degrade under repeated heat cycles, leading to external oil leaks. In severe cases, this can lead to coolant and oil mixing if the internal barrier fails.
Repair vs replace:
Oil cooler and seal replacement is a standard maintenance fix, though labour-intensive due to the tight packaging of the V8 engine bay. It does not typically require a full engine replacement unless severe overheating has occurred.
Read more about this issue
3. Timing Chain Tensioner Wear (Pre-2013 Units)
3. Timing Chain Tensioner Wear (Pre-2013 Units)
Typical onset:
60,000-100,000 miles
What happens:
Early iterations of the 5.0L supercharged V8 suffered from timing chain tensioner wear, leading to chain slap, stretched chains, and in severe cases, valve-to-piston contact. A distinct rattling noise on cold startup is the primary early warning sign.
Repair vs replace:
If caught early, tensioner and chain replacement is viable. If the chain has jumped time, a full reconditioned or rebuilt unit is required. Read our full timing chain failure guide.
Read more about this issue
Post-2013 508PS units received revised, far more robust timing chain tensioners and improved supercharger coupler materials, making them significantly more reliable and less prone to the early catastrophic timing failures seen in the 2009-2012 models .

Engine Variants
How to Confirm You Have the 508PS
The 508PS is Land Rover's specific high-output designation for the supercharged 5.0-litre V8 family. Confirming your exact code is critical because, while it shares its core architecture with naturally aspirated and lower-output supercharged variants, internal components and engine management are not universally interchangeable. WHERE TO FIND THE CODE: The engine code is stamped on a machined pad on the engine block, typically visible near the bellhousing or on the cylinder head cover. It will also be explicitly listed on your V5C registration document under "Engine Code" or "Engine Capacity", and can be decoded directly from your 17-character VIN. COMMONLY CONFUSED CODES: - 508PN: The naturally aspirated 5.0L V8. Externally similar but lacks the supercharger assembly, features different pistons, and has a lower power output, making it a non-straight swap. - AJ133: The broader Land Rover and Jaguar designation for the 5.0L supercharged family. While the 508PS is a high-output variant of the AJ133, specific ECU mapping, supercharger pulley ratios, and cooling plumbing may differ, requiring careful matching during replacement. Why fitting the wrong revision matters: Attempting to swap a naturally aspirated 508PN or a lower-output AJ133 long block into a 508PS chassis without updating the ECU, wiring loom, and supercharger plumbing will result in persistent fault codes, severe drivability issues, and potential sensor incompatibility. CLOSING LINE: Not 100% sure- Enter your registration above - we'll confirm your exact 508PS fitment before any quotes are sent.

Buying Guide
Buying a Replacement 508PS - What to Choose
Choosing the right replacement route depends on your budget, risk tolerance, and ownership goals. Here's a breakdown of your options.
Used:
A used Land Rover 508PS engine is only advisable if it comes with comprehensive, documented proof that the supercharger coupler and timing chain tensioners (if pre-2013) have already been replaced. Given the high performance and stress placed on this engine, the risk of inheriting hidden wear is significant without this history.
Reconditioned:
A reconditioned LandRover 508PS engine should specifically address this engine's known weak points: a new supercharger isolator coupler, updated timing chain tensioners, refreshed oil cooler seals, and all critical gaskets. This effectively resets the engine's reliability clock and is the most cost-effective way to secure long-term peace of mind for a high-value SUV. Compare reconditioned Land Rover 508PS engine options.
Rebuilt:
A full rebuild is justified for high-mileage examples, vehicles that have suffered from oil starvation, or if the cylinder bores show measurable scoring. An upgraded rebuild should include new pistons, a reground crankshaft, and a complete refresh of the oil pump and supercharger assembly, ensuring the engine can reliably handle another 100,000+ miles of heavy-duty use. View rebuilt Land Rover 508PS engine specifications.
Supply & Fit Line:
Buying through the EnginesMarket network means you can opt for a full supply and fit service, with the replacement engine installed by a Land Rover specialist and backed by a nationwide warranty. Learn more about supply and fit.
Vehicle Value Note:
The Land Rover 508PS is typically found in host vehicles (like the Range Rover L405 or Range Rover Sport L494) valued between £18,000 and £55,000+, heavily dependent on condition, mileage, and specification. For these modern, high-value chassis, an £8,000+ reconditioned Land Rover 508PS engine replacement represents a viable investment (well under 50% of the vehicle's total current market value), making replacement financially sound compared to older, lower-value platforms.

Question 4Should I buy a used or reconditioned 508PS engine-
A reconditioned Land Rover 508PS is strongly recommended over a used unit due to the high replacement cost of the supercharger assembly and the risk of inherited timing chain wear on pre-2013 blocks. A proper rebuild will systematically replace the supercharger isolator coupler, updated timing chain tensioners, and all critical seals. A used unit is only advisable with comprehensive, documented proof that these specific preventative repairs have already been completed.
