Jaguar XKR (X150) Oil Leaks & Coolant System Wear (AJ133 I6)
The AJ133 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 AJ133 V6. We replace timing chains, bearings, water pump and gaskets as standard on every AJ133 rebuild.
Because the XKR (X150) uses a completely different engine family from the V8 M178 fitted to the XK 63 and GT 63 S, parts and rebuild specifications don't cross over between them.
Source: Established AJ133 specialist pattern — timing chain, bearing and gasket wear across integrated-starter-generator inline-six units.

Jaguar XKR (X150)ENGINE OPTIONS
Every XKR (X150) is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR XKR ENGINE
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XKR already has instead — strip it down, pressure-test it, and replace every worn or damaged component (timing chain, tensioners, and guide rails) 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 XKR owners choose, and it's the one we'd recommend for most situations.
RECONDITIONED XKR 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.
REFURBISHED XKR 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.
REMANUFACTURED XKR 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 AJ133.
REPLACEMENT XKR 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.
USED XKR 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 XKR (X150) ENGINE

The XKR is the supercharged flagship of the XK range, carrying the AJ133 — a 5.0-litre supercharged V8 that was Jaguar's most powerful production engine of its era. It was fitted across the X150 generation from 2005 to 2014, and remains one of the most sought-after modern Jaguar V8s. The XKR sits above the naturally aspirated 4.2-litre and 5.0-litre XK models in the range, and was eventually succeeded by the even more powerful XKR-S. The X150 XKR was discontinued in 2014, but we continue to rebuild and replace engines for every one still on the road.
We continue to rebuild and replace AJ133 engines for every XKR (X150) on the road.
Jaguar XKR (X150) ENGINE CODES

AJ133 (X150 (2005–2014))
A 5.0-litre supercharged V8 fitted to the XKR from 2005 to 2014 (X150 generation). Known for the timing chain tensioner design flaw — see the callout above. We replace the timing chain, tensioners, and guide rails as standard on every AJ133 rebuild. Check Your AJ133 XKR → [link to quote form]

The XKR uses the AJ133 supercharged 5.0-litre V8 across the entire X150 production run. Before we quote or supply anything, we confirm:
Your exact engine code (AJ133) via registration or VIN
Your generation (X150)
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 XK quote — it protects you from paying for parts that don't fit your actual car.
