Jaguar S-Type 4.2 V8 Timing Chain Stretch

The S-Type 4.2 V8 uses the AJ-V8 engine. Across its production run, this engine is known for timing chain stretch, typically between 80,000-150,000km, signalled by a cold-start rattle. The chain tensioners and guide rails wear alongside the chain. We replace the timing chain, tensioners, guide rails, and gaskets as standard on every AJ-V8 rebuild.

Source: verified via multiple independent sources (AutoDoc, LR Engine Specialists), per VRF-jaguar-s-type.md. This claim applies to the AJ-V8 4.2L engine.

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.

01MOST POPULAR

REBUILDING YOUR S-TYPE 4.2 V8 ENGINE

Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your S-Type already has instead - strip it down, pressure-test it, and replace every worn or damaged component (timing chain, tensioners, guide rails, and gaskets) with updated OEM parts. You get a near-new engine with a 12-month unlimited-mileage warranty, without the compatibility risk of an unknown used unit. This is the option most S-Type 4.2 V8 owners choose, and it's the one we'd recommend for most situations.

From £4,500
02

RECONDITIONED S-TYPE 4.2 V8 ENGINES

"Reconditioned" is the term many owners search for when they mean the same thing as a rebuild - a full strip-down, inspection, and replacement of worn parts rather than a straight swap. If that's what you're after, our rebuild service is exactly that.

Learn more
03

REFURBISHED S-TYPE 4.2 V8 ENGINES

Similarly, "refurbished" often describes the same process from a different angle - restoring your existing engine to full working condition rather than replacing it outright. Our rebuild covers this.

Learn more
04

REMANUFACTURED S-TYPE 4.2 V8 ENGINES

Some owners specifically search for a "remanufactured" engine, expecting a unit rebuilt to original specification with updated components. That's consistent with what our rebuild service delivers.

Learn more
05

REPLACEMENT S-TYPE 4.2 V8 ENGINES

If your existing engine is beyond economical repair, we also offer full engine replacement and fitting - sourced and fitted by our team, with the same 12-month warranty.

Learn more
06

USED S-TYPE 4.2 V8 ENGINES

In some cases, a matched low-mileage used engine is the right call - particularly if you need your car back on the road quickly and your existing engine's damage is extensive. We can source and fit these too, though most owners who ask about used engines end up choosing a rebuild once they understand the compatibility risk a used unit carries. Enter your reg below and we'll talk you through both options honestly.

ABOUT THE Jaguar S-Type 4.2 V8 ENGINE

Jaguar E-Pace and Ingenium 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.

AJ-V8

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.

Jaguar S-Type 4.2 V8 ENGINE COMPATIBILITY

Black Jaguar E-Pace in a workshop

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 S-Type 4.2 V8 quote - it protects you from paying for parts that don't fit your actual car.
