Jaguar X-TYPE 2.5 V6 AWD Engine Specialists – Rebuilt In-House | 12-Month Warranty

From £5,600 - including full rebuild, head gasket replacement, fitment, road test, and 12-month warranty. This covers the AJ-V6 engine found in all X-TYPE 2.5 V6 AWD models (2001-2009). Our Billericay workshop uses genuine Jaguar components like timing chain kit LR096682 to ensure reliability. The complete process takes 5-7 working days at our Unit A5 Windsor Road facility.

With proper maintenance, yes. The AJ-V6 engine is robust but prone to head gasket issues after 100,000 miles. We've rebuilt over 185 X-TYPE 2.5 V6 AWD engines since 2009, incorporating reinforced MLS head gaskets and updated ignition components to address X200 generation weaknesses. For daily drivers, we recommend our comprehensive service package that includes throttle body cleaning and fuel system maintenance specific to the AJ-V6 architecture.

Head gasket failure is most common in high-mileage X-TYPE 2.5 V6 AWD vehicles, typically showing as coolant loss with no visible leaks. We replace the original composite gasket with a multi-layer steel (MLS) version during every rebuild at our Billericay workshop. This addresses the thermal cycling weakness specific to the AJ-V6 engine in X200 generation vehicles. The repair includes cylinder head resurfacing and torque sequence verification per JLR specifications.

Yes - the X200 generation X-TYPE requires specific ECU adaptation after engine work. At our Billericay facility, we use JLR SDD diagnostics to perform full immobilizer sync and adaptation. This ensures proper communication between the ECU and the rebuilt AJ-V6 engine, preventing 'check engine' lights and maintaining the vehicle's original driving characteristics. We follow JLR technical bulletin TSB-05-23-007 for complete system integration.

Absolutely - we specialize in vintage Jaguar engines. Our rebuild process for stored X-TYPE 2.5 V6 AWD vehicles includes ultrasonic cleaning of all components, replacement of degraded seals, and verification of the AJ-V6 engine's critical dimensions. We've successfully restored numerous X200 generation vehicles that had been in storage, ensuring they meet modern reliability standards while preserving their classic character. Our Billericay workshop has specific protocols for engines with ethanol-blended fuel residue.

Many believe the AJ-V6 engine is unreliable, but this stems from improper maintenance of the head gasket system. At our Billericay workshop, we've found that with our reinforced MLS head gasket installation and proper coolant maintenance, the X-TYPE 2.5 V6 AWD engine can reliably exceed 150,000 miles. The AJ-V6 is actually one of Jaguar's most durable V6 designs when maintained correctly. Our rebuilds at Unit A5 Windsor Road include upgraded components specifically designed to address the X200 generation's known weaknesses.
