Jaguar XF 5.0 V8 Timing Chain Tensioner Wear (AJ133/AJ133S, X250)
If your XF 5.0 V8 is from the X250 generation - roughly 2011 to 2015 - timing chain tensioner and guide wear is a well-documented design flaw on the AJ133/AJ133S V8, subject to a US class-action lawsuit covering this exact engine across multiple JLR models. The hardened steel tensioner piston wears an aluminium guide button over time, which can fail with little warning.
We replace the timing chain, tensioners, guides, and water pump as standard on every AJ133/AJ133S rebuild.
Source: verified via multiple independent sources including confirmed class-action lawsuit scope, X250 XF explicitly named per G-BRF. Applies to AJ133/AJ133S X250 generation only.
Jaguar XF 5.0 V8 (AJ133)ENGINE OPTIONS
Every XF 5.0 V8 (AJ133) is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR XF 5.0 V8 ENGINE
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XF 5.0 V8 already has instead - strip it down, pressure-test it, and replace every worn or damaged component (timing chain, tensioners, guides, water pump) 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 V8 owners choose, and it's the one we'd recommend for most situations.
From £4,500RECONDITIONED XF 5.0 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 moreREFURBISHED XF 5.0 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 moreREMANUFACTURED XF 5.0 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 AJ133.
Learn moreREPLACEMENT XF 5.0 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 moreUSED XF 5.0 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 5.0 V8 (AJ133) ENGINE

The XF 5.0 V8 uses the AJ133 engine family, a 5.0-litre V8 petrol unit that replaced the earlier 4.2-litre AJ34 in the X250 generation from around 2011. The naturally aspirated AJ133 powered the standard XF V8, while the supercharged AJ133S - producing significantly more power - powered the XFR flagship. Both share the same 5.0-litre V8 architecture and the same timing chain tensioner design, which is the key known wear point across this engine family.
The XF 5.0 V8 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.
Jaguar XF 5.0 V8 (AJ133) ENGINE CODES

AJ133 (Naturally Aspirated)
A 5.0-litre naturally aspirated V8 fitted to the XF V8 from around 2011 to 2015 (X250). Known for the timing chain tensioner design flaw - see the callout above. We replace the timing chain, tensioners, guides, and water pump as standard on every AJ133 rebuild.
Check Your AJ133 XF V8
AJ133S (Supercharged / XFR)
A 5.0-litre supercharged V8 fitted to the XFR from around 2011 to 2015 (X250). Shares the same AJ133 architecture and timing chain tensioner pattern as the naturally aspirated version. We replace the timing chain, tensioners, guides, and water pump as standard on every AJ133S rebuild.

The XF 5.0 V8 uses the AJ133 engine family across its X250 generation run. While the naturally aspirated and supercharged versions share the same core architecture, they have different ancillaries, cooling requirements, and ECU mapping. Before we quote or supply anything, we confirm:
Your exact engine code (AJ133 or AJ133S) via registration or VIN
Your X250 generation year and specification
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 V8 quote - it protects you from paying for parts that don't fit your actual car.
