OWNERSHIP VERDICT
Range Rover -
The Ownership Verdict
Verdict MetricOur Call
Overall Ownership Rating
★★★½ (3.5/5)
Replacement Economics
⚠️ The Widest Swing in the Range - a £6,500 engine is trivial in a £60,000 L405 and terminal in a £6,000 L322. Generation decides everything.
Reliability
★★★☆☆ - the engines are mostly better than the reputation; the air suspension and electronics around them earn the reputation
Most Reliable Engine
4.4 SDV8 (448DT) - the most dependable big diesel JLR made • BMW M57 Td6 (L322 era)
Highest-Risk Engine
3.0 TDV6/SDV6 (306DT) - crankshaft bearing • 3.6 TDV8 (368DT) - timing chain/tensioner
Best Used Buy
Late L405 4.4 SDV8 Vogue - flagship luxury, the range's strongest engine
Best Modern Buy
L460 D350 - the AJ20D6 six carries none of the old V6 legacy
Average Engine Replacement
£7,400 reconditioned, supply only [EM-QUOTE]
Most Common Failure Enquiry
306DT crankshaft bearing (L405 TDV6) [EM-VERIFIED]
Homepage Ranking
👑 Flagship - and home of our Most Dependable Big Engine (4.4 SDV8)
One-line verdict:
The Range Rover is where engine economics get emotional - the same reconditioned V8 that's a rounding error on an L460 invoice is a death sentence for a cheap L322, and knowing which side of that line your car sits on is worth more than any spec sheet.

01306DT Crankshaft Bearing Failure
Catastrophic
Catastrophic
The L405 TDV6/SDV6's defining risk - cold-start knock is the warning, and once the bottom end lets go there's rarely anything to rebuild. £6,500–£9,500 recon [EM-QUOTE].

02368DT Timing Chain & Tensioner Failure
Immediate
Immediate
The 3.6 TDV8's known weakness - chain and guide wear with snap risk on neglected oil intervals. Affects L322 2006–2010.

03AJ133 5.0 Supercharger & Chain Guide Wear
Immediate

Supercharger nose bearing whine plus timing chain guide wear on early 5.0s - noisy warning, expensive silence. Affects L322/L405 petrols.

04P38 Rover V8 Liner & Head Issues
Immediate
Immediate
Slipped cylinder liners and porous blocks on the 4.0/4.6 - the failure that halved P38 values. Top-hat liner rebuilds fix it permanently.

05Air Suspension Compressor Failure
Catastrophic

Every generation from Classic LSE onward; compressor burnout presents a fire risk. The most common non-engine enquiry across all Range Rovers.

Short-run D300/D350s dilute oil through interrupted DPF regens; P400e engines that never run suffer their own neglect patterns. Modern problems for modern Range Rovers.

Insights from the data:
Interesting insight: A £150,000 flagship generating 184 engine enquiries in its first years [EM-VERIFIED] is unusual - L460 demand is dominated by extended-warranty and due-diligence questions, not failures. Owners are nervous about the headlines, not the engines. (Editorial synthesis - specialist sense-check before publishing.)
L405 enquiries concentrate heavily on the TDV6/SDV6 - the SDV8, despite the biggest bills, barely features in failure enquiries. The most expensive engine is the cheapest to own per mile. (Editorial synthesis.)
368DT demand is declining in step with L322 values - the same end-of-economics curve we track on the Discovery 3. (Editorial synthesis.)
Editorial Pull-Quote
The One Thing We'd Tell Every Range Rover Buyer
“If you buy one Range Rover based on this page, buy a late L405 4.4 SDV8 - the most dependable big engine JLR ever made, wrapped in the last of the pre-L460 depreciation. And if a £7,000 L322 is calling you: the car is £7,000, the ownership isn't.”

The Range Rover rule -
generation is destiny: The same £8,000–£12,000 SDV8 recon is 15% of a nice L405's value (✅ Safe), 60%+ of a tired L322's (⚠️ threshold), and more than a whole P38 (❌ walk away, or buy a used engine). Before any Range Rover engine decision, value the car first - we'll do it with you for free.
Value the car first; the engine decision follows.

Buyer Profile
Rating
Our Verdict
Family Buyer
★★★★★
★★★★★
An L405 is a magnificent family flagship - budget running costs like a second mortgage payment and it will never disappoint.
Daily Commuter
★★★★★
★★★★★
The wrong tool. Short runs punish the diesels' DPFs and the PHEVs only make sense with a driveway charger and discipline.
Towing & Working Use
★★★★★
★★★★★
3,500kg with imperious ease - the SDV8 L405 may be the finest tow car ever sold in Britain.
Budget Owner
★★★★★
★★★★★
The most dangerous badge on this site for a tight budget. A cheap L322 or P38 is not a cheap Range Rover - it's an expensive one with the first year's bills prepaid by nobody.
Collector / Keeper
★★★★★
★★★★★
Classics are appreciating assets worth proper engine investment; a cherished SDV8 L405 is a future classic being written now.

FAQ
Range Rover Frequently Asked Questions
1How much does a Range Rover engine replacement cost in the UK?
Reconditioned units run £2,500–£14,000 supply only depending on generation and engine [EM-QUOTE] - from a Classic Tdi at £2,500–£4,500 to the L460's P530 V8 at £9,000–£14,000. Fitting adds £650–£2,100. Use our calculator for a personalised figure.
2Which Range Rover engine is the most reliable?
The 4.4 SDV8 (448DT) - the lowest failure-enquiry rate of any big JLR engine in our data despite the highest replacement cost. From the BMW era, the M57 Td6 deserves the same reputation.
3Which Range Rover engine should I avoid?
The 3.0 TDV6/SDV6 (<a href='https://landroverengine.uk/engine/306dt'>306DT</a>) without documented oil-interval history - its crankshaft-bearing failure leaves nothing to rebuild. The 3.6 TDV8 (368DT) needs its timing-chain history evidenced. Unrebuild P38 V8s carry liner risk priced into every listing.
4How do I know if my Range Rover engine needs replacing?
By engine: cold-start knock (306DT), timing chain rattle (368DT, AJ133), supercharger whine (5.0 SC), coolant loss and overheating (P38 V8). Use our diagnostic calculator for a personalised assessment.
5Is it worth replacing a Range Rover engine?
Entirely generation-dependent. L405/L460: almost always . L322: run the maths - a £6,000 car cannot carry an £8,000 engine ⚠️. P38/older: used engine or specialist rebuild as restoration, not repair. Use the Ownership Decision Tool for your car.
6Which Range Rover should I buy?
Late L405 SDV8 for the sweet spot; L460 D350 if the budget is new-car sized; a sorted BMW-era L322 Td6 for the informed bargain; a Classic if your heart has already decided.
7How do I find my Range Rover engine code?
On the VIN plate and vehicle documentation; block stampings vary by era. Or tell us your generation and variant (SDV6, SDV8, D350, P530) and we'll identify it.
8Range Rover vs Range Rover Sport - which is more reliable?
Mechanically they're siblings - shared platforms and engines mean shared strengths and shared risks. The Sport's harder driven life shows in our enquiry patterns; the full-size car's extra weight works everything else harder. Buy on engine and history, not badge. Read the full head-to-head →
