Production years 2005–2010 meet Euro 4 emissions standards .
The Jaguar SV8TS is a 4,196 cc V8 petrol engine developed for grand tourer platforms (2005–2010). It features DOHC architecture with four valves per cylinder and sequential fuel injection to ensure responsive power delivery. Designed for Euro 4 compliance, it balances high performance with emissions control through advanced engine management.

The Jaguar SV8TS was used across Jaguar's X150 platform with longitudinal mounting and shared architecture with Daimler for select applications. This engine received platform-specific tuning-shortened intake runners in the XKR and revised exhaust manifolds in the XK-and from 2008 the facelifted XK LCI adopted updated ECU mapping and swirl flap design, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The SV8TS engine is fundamentally robust with good longevity when properly maintained. Pre-2008 models are more prone to swirl flap issues, while later revisions show improved reliability. Regular oil changes with correct specification (10W-40 WSS-M2C159-D) and use of premium fuel are essential. Well-maintained units can reliably exceed 180,000 km.
The most documented issues are inlet manifold swirl flap failure (especially pre-2008), intake valve carbon buildup due to port injection, and oil leaks from ageing valve cover gaskets. Timing chain tensioner wear can occur with poor maintenance. These are addressed in Jaguar service bulletins and technical documentation.
The SV8TS 4.2L V8 petrol engine was used in the Jaguar XK (X150, 2005–2010) and Daimler Super Eight (2006–2009). All models comply with Euro 4 emissions standards.
Aftermarket ECU tuning is common on the SV8TS platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In combined driving, the SV8TS achieves approximately 15.5–17.5 L/100km (16–18 mpg UK). Highway consumption is around 13.0 L/100km (22 mpg UK), while city driving may reach 19.0 L/100km (15 mpg UK). Real-world economy depends on driving style and vehicle weight, with the XKR being slightly less efficient than the XK.
Yes, the Jaguar SV8TS is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal engine damage. Maintaining the chain system through proper oil and timely servicing is critical to prevent costly repairs.
Jaguar specifies SAE 10W-40 synthetic oil meeting WSS-M2C159-D standard. This oil is essential for maintaining hydraulic lifters, chain tensioners, and valve train longevity. Change intervals should not exceed 12,000 km or one year, whichever comes first, to ensure optimal engine protection.
