Jaguar S-Type 4.2 V8 Oil Leaks & Coolant System Wear (engine I6)
The engine is a sophisticated 3.0-litre inline-six with an integrated starter-generator and electric auxiliary compressor — a more modern and efficient design than the older engine V6. We replace timing chains, bearings, water pump and gaskets as standard on every engine rebuild.
Because the S-Type 4.2 V8 uses a completely different engine family from the V8 M178 fitted to the Jaguar 63 and GT 63 S, parts and rebuild specifications don't cross over between them.
Source: Established engine specialist pattern — timing chain, bearing and gasket wear across integrated-starter-generator inline-six units.
Jaguar S-Type 4.2 V8ENGINE OPTIONS
Every S-Type 4.2 V8 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR S-Type 4.2 V8 ENGINE
We rebuild the engine your S-Type 4.2 V8 already has instead of selling you a used engine of unknown history — strip it down, pressure-test it, and replace every worn or damaged component (timing chains, bearings, water pump, gaskets) with updated OEM parts. Near-new performance with a 12-month unlimited-mileage warranty.

ABOUT THE Jaguar S-Type 4.2 V8 ENGINE
The S-Type 4.2 V8 uses the AJ-V8 — a 4.2-litre naturally aspirated V8 petrol engine. It was fitted to the X200-generation S-Type from its introduction in 1999 until the model was discontinued in 2008. The AJ-V8 was Jaguar's flagship engine of the era and is a completely different unit from the AJ-V6 found in the smaller-engined S-Type variants.
We continue to rebuild and replace engine engines for every S-Type 4.2 V8 on the road.
Jaguar S-Type 4.2 V8 ENGINE CODES
A 4.2-litre naturally aspirated V8 petrol fitted to the S-Type from 1999 to 2008 (X200 generation). Known for timing chain stretch over time — see the callout above. We replace the timing chain, tensioners, guide rails, and gaskets as standard on every AJ-V8 rebuild. Check Your AJ-V8 S-Type 4.2 V8 → [link to quote form]
Check Your engine S-Type 4.2 V8Jaguar S-Type 4.2 V8 ENGINE COMPATIBILITY
The S-Type 4.2 V8 uses the AJ-V8 engine across its entire production run. While there were no major engine code changes within the S-Type's lifecycle, ensuring the correct specification is still critical — particularly when it comes to ancillaries, electronics, and ECU matching. Before we quote or supply anything, we confirm:
- Your exact engine code (AJ-V8)
- Your generation (X200)
- Drivetrain and ancillary specification
- Any electronics or ECU considerations specific to your exact build
This is why we always start with your registration rather than a generic Jaguar quote — it protects you from paying for parts that don't fit your actual car.
