ENGINE SUPPLY & REPLACEMENT EXPERTS

Jaguar XJ Engines Replacement Specialists, Fast Turnaround with Warranty

We sell Jaguar XJ engines for sale across the UK. A serious engine fault does not have to mean a new engine from the main dealer. We supply used, reconditioned and rebuilt Jaguar XJ engines with the same performance and reliability for up to 40% less than a new crate engine.

Engine Rebuild covers all generations of the Jaguar XJ, in petrol and diesel. Before any supply or fitting work, we match every Jaguar XJ engine to the correct engine code, such as the 306DT diesel, the AJ126 V6 and the AJ133 V8. Our in house rebuilding facility means your engine is stripped, checked and rebuilt by our own team, not sent to a third party.

We offer Jaguar XJ engines for sale on a supply only basis or as a full supply and fit service. Every engine is backed by warranty options, and we can arrange recovery for a non-running car. We also run engine diagnostics to find the real fault before we recommend a repair or a replacement.

Used, Reconditioned and Rebuilt Jaguar XJ Engines

Used Jaguar XJ engines come from existing vehicles and are sold without a full strip down. They are the cheapest option when price and speed matter. Every used Jaguar XJ engine is checked for the correct engine code, condition, mileage and included parts. Reconditioned Jaguar XJ engines are the longer term option. The engine is stripped down to the block, and every part is inspected, machined, repaired or replaced where needed. The engine is then rebuilt and tested before sale. You get near new performance for a fraction of the price.

Jaguar XJ engine rebuilds suit engines where the main structure is still sound. We strip it down and inspect the block, crankshaft, cylinder head, pistons, rods and bearings. The rebuild is done to manufacturer standards, and the engine is tested before it goes back in the car. We also offer engine diagnostics before any work starts. Advanced diagnostic checks identify the fault first, so you only pay for the right fix. If a replacement is the better option, we supply one with clear support from start to finish. Our team will tell you which Jaguar XJ engine for sale suits your budget.

Jaguar XJ Engine Supply and Fitting

We follow a four step process for every Jaguar XJ engine replacement.

  • Step one: vehicle and fault assessment. We check the symptoms, engine condition and history.

  • You can choose supply only or supply and fit. Experts check the engine code before anything is confirmed.
  • Warranty options are available on every Jaguar XJ engine for sale. The warranty period depends on the engine condition and the work done.

FREQUENTLY ASKED QUESTIONS

Explore common questions about replacement engines, fitting, costs and warranties..

The 3.0 litre V6 supercharged petrol engine is widely considered the most reliable Jaguar XJ engine. It experiences far fewer critical mechanical failures than early diesel or early 5.0 V8 models when serviced regularly.

A Jaguar XJ engine typically lasts between 100,000 and 150,000 miles. Frequent oil changes and timely timing chain replacements can extend engine life beyond 200,000 miles.

Crankshaft failure in 3.0 litre TDV6 diesel engines occurs due to oil starvation, oil dilution, and worn main bearings. Increased friction causes the main bearings to spin, which snaps the crankshaft.

The most common issues include timing chain wear, crankshaft snapping on 3.0 diesels, water pump failure on 5.0 V8 models, and coolant leaks from brittle plastic hoses.

A Jaguar XJ engine rebuild generally costs between £2,500 and £5,500+ in the UK. The overall price depends on the engine code, the extent of internal damage, and required machine work.

Key symptoms include a metallic rattling sound on cold starts, rough idling, a "Restricted Performance" dashboard warning, and engine misfires.

Rebuilding a Jaguar XJ engine usually takes 5 to 10 working days. The exact duration depends on parts availability and workshop capacity.

Yes. A reconditioned engine replaces worn internal components with new OEM or upgraded parts. The engine block is cleaned, re-machined, and pressure tested to match original factory standards.

A rebuilt engine repairs or replaces only defective parts. A reconditioned engine undergoes a full teardown, professional machining, and complete replacement of all wear components.

Overheating in 5.0 V8 engines usually stems from failed water pumps or cracked plastic coolant crossover pipes. Rapid coolant loss leads to blown head gaskets and warped cylinder heads.

Change engine oil every 5,000 to 7,000 miles, replace plastic coolant pipes early, address cold start timing chain rattles immediately, and check oil levels weekly.

Yes. Professional UK engine reconditioners provide up to a 12 month warranty covering both parts and labour.

No. A snapped crankshaft causes severe structural damage to the engine block and main bearing seats. Resolving this fault requires a reconditioned engine block or full replacement engine.
