We rank the costliest Land Rover and Range Rover engine repairs using real 2025 UK enquiry data, supplier quotes, and independent labour rates – and apply our 60% repair-to-value threshold to show you when a repair becomes a write‑off.
The short answer: the most expensive Land Rover repair is a 508PS SDV8 engine replacement, costing £8,000–£12,000 in recon supply and fit – but the 306DT crankshaft failure is the most commonly quoted catastrophic repair, at £6,500–£9,500. The real cost to you depends on the vehicle's value: a repair that exceeds 60% of the car's worth is usually a write‑off.

We've ranked the costliest engine repairs across the Land Rover and Range Rover range, based on real 2025 UK supplier quotes and labour hours from our proprietary data. The table shows reconditioned supply-and-fit costs, used alternatives, and the typical vehicle value context – plus our verdict on whether the repair is financially viable.

Verdicts assume average condition and typical trade valuation. A well‑maintained, low‑mileage example may justify spending above the threshold – our framework explains how to make that judgment. All costs are supply‑and‑fit at independent specialist rates; main dealer costs can be 30–50% higher.
The most expensive repair isn't always the one that breaks the bank – it's the one that exceeds 60% of the vehicle's value. Here's how to calculate whether your Land Rover repair is financially viable.
Not all expensive repairs are equal. Labour hours, parts availability, and vehicle access all affect the final bill. This table shows the full breakdown for each of the top eight costliest engines.
| Engine | Recon Supply | Used Supply | Labour Hours | Labour Cost (Indie) | Typical Total S&F |
|---|---|---|---|---|---|
| 508PS SDV8 | £8,000–£12,000 | £4,500–£7,000 | 16–20 | £1,040–£1,300 | £9,040–£13,300 |
| 306DT TDV6/SDV6 | £6,500–£9,500 | £3,500–£5,500 | 15–20 | £975–£1,300 | £7,475–£10,800 |
| 448DT SDV8 | £6,000–£9,000 | £3,500–£6,000 | 18–24 | £1,170–£1,560 | £7,170–£10,560 |
| 368DT TDV8 | £5,500–£8,000 | £3,000–£5,000 | 14–18 | £910–£1,170 | £6,410–£9,170 |

Some repairs are so costly relative to the vehicle's value that the only sensible answer is to scrap or sell for parts. Here are the cases where our data shows owners walk away – and they're right to.
With recon costs at £6,500–£9,500, a Discovery 4 worth £9,000 gives a ratio of 72–105% – well above the 60% threshold. Our 306DT write‑off guide covers this in detail.
Recon costs £5,000–£7,500 on a vehicle worth £6,000 – that's 83–125%. The oil pump failure is catastrophic, and the vehicle's age rarely justifies the spend. See our 276DT oil pump failure page.
Pre‑2010 3.6 TDV8 units have crankshaft fracture risks. With recon at £5,500–£8,000 and typical L322 values under £10,000, this repair often exceeds 60%. Our 368DT Knowledge Centre warns against early examples.
Though cheaper at £2,000–£3,500, a Freelander 2 often sits under £4,000 – making the ratio 50–87%. Combined with other age‑related issues, the honest answer is frequently to scrap. Our Freelander economics explains.
The 508PS SDV8 (4.4 V8) has the highest reconditioned supply‑and‑fit cost at £8,000–£12,000 [EM-QUOTE]. However, the 306DT crankshaft failure is the most commonly quoted catastrophic repair, with 980 enquiries in 2025 [EM-VERIFIED].
We divide the repair cost by the vehicle's current trade value. If the result exceeds 60%, we recommend scrapping or selling for parts. For example, a £7,800 repair on a £9,000 Discovery 4 is 87% – a clear write‑off. Full methodology on our framework page.
Yes – a used unit can save 30–50% but carries higher risk. For the 306DT, a used engine costs £3,500–£5,500 versus £6,500–£9,500 recon. However, the 306DT's bearing failure can recur if the used engine is not properly inspected. Our guide explains the trade‑offs.
Range Rover L405 and L494 models with the 508PS or 306DT engines top the list. However, the average repair cost is lower than the peak – most owners spend £3,000–£6,000. See our average cost by model for full details.
