Jaguar XF 4.2 V8ENGINE OPTIONS

Every XF 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 XF 4.2 V8 ENGINE

Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XF 4.2 V8 already has instead - strip it down, pressure-test it, and replace every worn or damaged component 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 XF 4.2 V8 owners choose, and it's the one we'd recommend for most situations.

From £4,500
02

RECONDITIONED XF 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 XF 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 XF 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 on the AJ34.

Learn more
05

REPLACEMENT XF 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 XF 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 XF 4.2 V8 ENGINE

Jaguar E-Pace and Ingenium engine

The XF 4.2 V8 uses the AJ34 - a 4.2-litre naturally aspirated V8 petrol engine. It was fitted from 2007 until approximately 2011 across the X250 generation, before being superseded by the 5.0-litre AJ133 V8. The XF 4.2 V8 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.

We continue to rebuild and replace AJ34 engines for every XF 4.2 V8 on the road.

Jaguar XF 4.2 V8 ENGINE COMPATIBILITY

The XF 4.2 V8 uses the AJ34 engine across the X250 generation. Before we quote or supply anything, we confirm:

Your exact engine code (AJ34) via registration or VIN

Your generation (X250)

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 XF quote - it protects you from paying for parts that don't fit your actual car.
