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 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.

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.

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.

The AJ133S shares the same architecture and timing chain pattern as the naturally aspirated AJ133, and we service it to the same standard. Do you supply used XF 5.0 V8 engines? Yes, in some cases a matched low-mileage used engine is the right option. Our team will advise honestly once we've matched your registration and understood your situation.
