Is It Worth Replacing a Range Rover Engine? Cost Guide 2026

Q: How much does it cost to replace a Range Rover engine?

Supply-only costs range from £3,000–£5,000 for a 4.4 V8 (non-turbo) to £8,000–£12,000 for a 508PS 4.4 SDV8. Fitted costs add 8–24 hours labour at £65–£75/hr (or significantly more in London/SE). Full data is in our Replacement Cost by Engine Code table.

Q: Which Range Rover engine is most reliable?

The 448DT 4.4 SDV8 is the most reliable large diesel in the Range Rover range, with no catastrophic design flaw. The 508PS 4.4 SDV8 is similarly durable but more expensive to replace. The 306DT SDV6 has a known crankshaft bearing failure risk — read our 306DT Crankshaft Bearing Failure page for full detail.

The short answer: yes, if the fitted replacement cost is less than 60% of your Range Rover's current market value. For an L405 with the durable 448DT 4.4 SDV8, that's almost always yes. For an ageing L322 with the 368DT TDV8, it's often no. The answer depends entirely on your generation, engine and the vehicle's current condition — not on the original list price.

A 448DT 4.4 SDV8 recon supply costs £6,000–£9,000 [EM-QUOTE], fitted £7,500–£10,500 — safe on any L405 worth £14,000+
A 306DT SDV6 recon costs £6,500–£9,500 supply [EM-QUOTE], fitted £7,500–£11,000 — watch zone on sub-£14,000 L405 examples
A 368DT 3.6 TDV8 recon costs £5,500–£8,000 supply [EM-QUOTE] — but L322 values of £4,000–£12,000 often make this a scrap decision
The 508PS 4.4 SDV8 (£8,000–£12,000 supply) [EM-QUOTE] is the most expensive but fitted on high-value L405s where the R-to-V ratio stays well below 60%

How the 60% Rule Decides Whether to Replace a Range Rover Engine

This is the single most important number in any Range Rover ownership decision. Here is how it works, why it exists, and how to apply it to your own vehicle.

The calculation is simple: divide the full supply-and-fit cost of the replacement engine by your Range Rover's current market value. If the result is below 60%, the repair is financially sensible. Above 60%, the honest verdict is usually to scrap the vehicle or sell it for parts.

Why 60% for Land Rover and Range Rover? Our enquiry data [EM-VERIFIED] shows that owners who spend less than 60% of their vehicle's value on an engine replacement are substantially more likely to report the decision as worthwhile a year later. Above that line, the split shifts sharply toward regret or early re-sale. The threshold is set deliberately conservative — slightly below the point our data suggests most owners actually break even — to account for the uncertainty in any single vehicle valuation.

What about the 70% threshold used by BMW and Mercedes? BMW and Mercedes-Benz sit at 70% in our data, reflecting a higher typical parts and labour baseline for those brands. The Range Rover threshold is 60% because the parts and labour baseline in our enquiry data is genuinely different — not because one brand is "better" than another. Full detail on this is on our Repair, Replace or Scrap Framework page.

The most common mistake: using the original purchase price or the car's value five years ago. The calculation only works against today's trade or private sale value. A ten-year-old L322 is not worth what you paid — the ratio only works with current figures.

Key rule for Range Rover owners:

The 60% threshold is a starting guide, not an absolute cut-off. A low-mileage, immaculate L405 with full service history may justify a repair above the threshold. A tired L322 with a failing gearbox and suspension probably won't clear it even below. Always assess the whole vehicle.

Range Rover Engine Replacement — By Generation

Each Range Rover generation has a different value profile and different engine risks. This is how the 60% threshold applies across the range.

Range Rover L322 (2002–2012)

Typical value: £4,000–£12,000 [ESTIMATED]

Primary engines: 368DT 3.6 TDV8 · 4.4 V8 · 4.2/5.0 Supercharged

Recon supply costs: £5,500–£9,000 [EM-QUOTE]

R-to-V verdict: 🔴 Scrap risk on most sub-£8k examples

The L322 is the most financially vulnerable Range Rover when an engine fails. Values are low enough that even a £5,500 fitted repair on a £6,000 car is 92% of the vehicle's value — a clear scrap verdict. The 368DT TDV8 is particularly risky (crankshaft fracture, timing chain tensioner failure), and the 5.0 Supercharged V8 has its own timing chain issues. Only the most immaculate, low-mileage L322s with the 4.4 V8 (non-supercharged) consistently clear the threshold.

⚠

Range Rover L405 (2012–2021)

Typical value: £14,000–£55,000 [ESTIMATED]

Primary engines: 306DT SDV6 · 448DT 4.4 SDV8 · 508PS 4.4 SDV8

Recon supply costs: £6,000–£12,000 [EM-QUOTE]

R-to-V verdict: ✅ Safe on most examples

The L405 is the sweet spot for replacement viability. Strong residual values mean even the most expensive engine (£8,000–£12,000 supply, £9,500–£14,000 fitted) stays well below 60% on most examples. The 448DT 4.4 SDV8 is particularly durable — no catastrophic design flaw — making it the safest Range Rover engine to own. The 306DT SDV6 is riskier (crankshaft bearing failure), but L405 values are high enough to absorb the cost on most examples. Our SDV6 case study explores this in detail.

✅

Range Rover L460 (2022–present)

Typical value: £55,000–£120,000 [ESTIMATED]

Primary engines: 306PS 3.0 Ingenium Petrol · 306DT D300/D350

Recon supply costs: £4,500–£9,500 [EM-QUOTE]

R-to-V verdict: ✅ Very safe

The newest generation is the safest of all. L460 values are so high that even the most expensive engine replacement (£9,500 supply, £11,500 fitted) is only 10–20% of the vehicle's value. The Ingenium 3.0 petrol and diesel units are relatively new, with limited long-term data, but the financial buffer is so large that the economics page is almost irrelevant — the decision is about availability and reliability, not cost.

Range Rover Engine Replacement — By Engine Code

Worked Example: Should You Replace a Range Rover SDV6 Engine?

Real numbers, real working — the exact case explored in full in our related case study, "Why £2,000 of Value Changes the Verdict."

The Situation

Vehicle2016 Range Rover L405 SDV6 (306DT)

Mileage94,000 miles

Fault306DT crankshaft bearing failure

Quote received (Recon S&F)£8,200

Current trade value£13,500 [ESTIMATED]

The Calculation

Repair-to-value ratio£8,200 ÷ £13,500 = 61%

Threshold60%

Result⚠️ Watch zone

If value were £11,000 instead75% — Scrap

If value were £15,500 instead53% — Safe

The verdict: this specific L405 sits right at the edge of the threshold — which is exactly the kind of case our data shows people get wrong most often, in both directions. A ✅ Safe verdict two thousand pounds of valuation lower would have been a 🔴 Scrap verdict on the same car with the same fault. This is why we always show the working rather than a single traffic-light colour with no maths behind it.

When Replacing a Range Rover Engine Is Not Worth It

A site that always recommends replacement is a sales funnel wearing an editorial costume. Sometimes the right answer is to walk away, and we say so plainly.

🚫

L322 with 368DT TDV8, Higher Mileage

Late in its value curve, a 368DT TDV8 replacement frequently exceeds 70% of trade value. Combined with the known crankshaft fracture and timing chain tensioner issues, the honest advice is usually to walk away. Our L322 economics page covers this in detail.

Typical fitted cost: £6,500–£9,500 [EM-QUOTE]

Typical L322 value: £4,000–£8,000 [ESTIMATED]

R-to-V: 81–238% — 🔴 Scrap

🚫

L320 Range Rover Sport (any major engine failure)

The early L320 with the 276DT or 368DT is a high-risk proposition. Oil pump failure on the 276DT or crankshaft fracture on the 368DT often writes the car off. Values are low enough that even a £6,000 fitted repair on a £7,000 car is 86% of the vehicle's value. The same applies to the 5.0 Supercharged V8 with timing chain failure.

Any Range Rover Below £6,000 Trade Value

Below this line, almost no engine fault clears the 60% threshold. Selling for parts or to a specialist breaker is usually the financially honest outcome — our scrap value guide explains how that figure is reached, and Most Expensive Land Rover Repairs shows where this threshold gets tested hardest.

Our Verdict: Is It Worth Replacing a Range Rover Engine?

Based on the full 2025 dataset — 9,000+ real enquiries, 24,650 quote requests, and hundreds of specialist interviews — here is our definitive answer.

The short verdict:

Yes, if you own an L405 or L460 with the 448DT, 508PS, or 306PS Ingenium petrol. These engines are either durable enough to rarely fail catastrophically, or the vehicle value is high enough to comfortably absorb the replacement cost.

No, if you own an L322 or early L320 with the 368DT or 276DT. The combination of high failure risk and low residual values means the repair almost never makes financial sense.

Maybe, if you own an L405 or L494 with the 306DT SDV6. These are the cases our data shows people get wrong most often — the answer depends on the exact value of your car. Use the Repair vs Replace Calculator with your own valuation.

🏆

Best-Case Range Rovers to Own

1. L405 with 448DT 4.4 SDV8 — durable, no catastrophic design flaw, high values
2. L405 with 508PS 4.4 SDV8 — expensive to replace but high values absorb the cost
3. L460 with 306PS 3.0 Ingenium Petrol — very high values, replacement cost is a fraction of vehicle value
4. L405 with 306DT SDV6 (high-value examples) — risk is real, but high values often keep R-to-V below 60%

🚫

Worst-Case Range Rovers to Own

1. L322 with 368DT 3.6 TDV8 — crankshaft fracture risk + low values = frequent write-offs
2. L320 with 276DT 2.7 TDV6 — oil pump failure kills engine, values too low to justify repair
3. L322 with 5.0 Supercharged V8 — timing chain issues + ageing vehicle values = high write-off risk
4. L405 with 306DT SDV6 (low-value examples) — same engine risk, but sub-£12k values often fail the threshold

The honest conclusion: the most financially sensible Range Rover to own is an L405 with the 448DT 4.4 SDV8 — it is durable, has no catastrophic design flaw, and retains enough value to absorb a replacement. The most financially risky is an L322 with the 368DT TDV8, where the replacement cost often exceeds the vehicle's value.

Frequently Asked Questions

Is it worth replacing a Range Rover engine?

It depends on your generation, engine and vehicle value. The 60% rule says: if the fitted replacement cost is less than 60% of your Range Rover's current market value, it's usually worth it. L405 and L460 owners almost always clear this threshold. L322 and early L320 owners often don't.

How much does it cost to replace a Range Rover engine?

Supply-only costs range from £3,000–£5,000 for a 4.4 V8 (non-turbo) to £8,000–£12,000 for a 508PS 4.4 SDV8. Fitted costs add 8–24 hours labour at £65–£75/hr (or significantly more in London/SE). Full data is in our Replacement Cost by Engine Code table.

Which Range Rover engine is most reliable?

The 448DT 4.4 SDV8 is the most reliable large diesel in the Range Rover range, with no catastrophic design flaw. The 508PS 4.4 SDV8 is similarly durable but more expensive to replace. The 306DT SDV6 has a known crankshaft bearing failure risk — read our 306DT Crankshaft Bearing Failure page for full detail.

Should I replace a 306DT SDV6 engine in an L405?

If the fitted replacement cost is below 60% of your L405's value, yes. The problem is that L405 values vary widely — a £8,200 fitted repair on a £13,500 car is 61% (watch zone), while the same repair on a £10,000 car is 82% (scrap). Use our calculator with your own valuation.

What is the 60% rule for Range Rover engine replacement?

The 60% rule is our repair-to-value threshold: if the fitted replacement cost is more than 60% of your Range Rover's current market value, the honest verdict is usually to scrap or sell for parts. Full explanation is on our Repair, Replace or Scrap Framework page.

Is a Range Rover L322 worth repairing?

Usually no, unless it's a low-mileage, immaculate example with the 4.4 V8 (non-turbo). The 368DT TDV8 and 5.0 Supercharged V8 have expensive failure modes, and L322 values are low enough that most repairs exceed 60% of the vehicle's value. See our scrap value guide for more detail.
