ABOUT THE
JAGUAR AJ30 ENGINE
The AJ30 is Jaguar's 3.0-litre V6 petrol engine, produced from 1999 to 2012. It was derived from Ford's Duratec V6 family and used across two Jaguar model lines - the X-Type and the XF. The engine is generally well-regarded for its reliability, though certain components require attention as mileage accumulates.
JAGUAR AJ30
APPLICATIONS BY MODEL
Across the X-Type, the AJ30 powered the 3.0 V6 variant throughout the model's production run (2001-2009). The engine was the range-topping petrol option in the X-Type, providing the V6 performance that distinguished the range-topper from the four-cylinder variants. The XF continued with the AJ30 in its early years (2008-2012), using the same 3.0-litre V6 as the base petrol engine before the range transitioned to the newer AJ126 and Ingenium families.
JAGUAR AJ30
ENGINE COMPATIBILITY
Because the AJ30 spans two different model lines with different chassis configurations, compatibility comes down to confirming your exact vehicle, which we do by registration. A V6 from an X-Type isn't a direct match for a V6 from an XF - ancillaries, mounting, and ECU calibration all differ. Before we quote or supply anything, we confirm your exact vehicle.

Applications We Work On
AJ30 in the X-Type (X400, 2001-2009)
The AJ30 in the X-Type is one of the applications we work on regularly, across the 3.0 V6 variant (2001-2009).
Starting from:

AJ30 in the XF (X250, 2008-2012)
The AJ30 in the XF is one of the applications we work on, in the 3.0 V6 variant (2008-2012). AJ30 Symptoms That Justify Inspection The following symptoms don't automatically mean the AJ30 requires a rebuild. Proper diagnosis comes first. Sudden loss of oil pressure (sump/line failure) Engine failure with no warning Rough idle (intake manifold issues) Loss of power Check engine light

OUR WORKSHOP VIEW OF
THE JAGUAR AJ30
Built, rebuilt and tested by engineers who work on Jaguar engines every day.
Here's our practical view of the AJ30 across its X-Type X400, XF X250 applications.
APPLICATIONS WE SEE:
The AJ30 appears in the X-Type and early XF - two distinct applications with different chassis layouts and component arrangements.
WHAT WE REPLACE:
Main bearings, connecting rod bearings, timing chain components as required, complete gasket and seal set, and oil filter housing gasket as standard on every rebuild.
KNOWN ISSUES:
The AJ30 has a known vulnerability to catastrophic oil loss due to poor design of the sump and oil lines, which can cause sudden oil pressure loss and engine failure. The intake manifold geometry electric drive is also known for low reliability, and cracked intake gaskets can cause suction issues. While the engine is generally well-regarded, parts are expensive when replacement is needed.
AJ30 REBUILD INFORMATION
Typical rebuild scope:
A TYPICAL
JAGUAR AJ30 REBUILD
The following describes a typical rebuild scope for this engine - illustrative of the work involved, not a specific customer job. Real case studies from our own completed work will replace this section once available.
The AJ30 is known for catastrophic oil loss due to sump and line design - we inspect the oil system thoroughly on every rebuild as a priority. The electric drive for intake geometry can also fail, and cracked intake gaskets can cause suction issues. A full rebuild addresses these known vulnerability points alongside the standard component replacement and inspection scope.
01INSPECTION & STRIP-DOWN
Careful inspection of the crankshaft, cylinder head, and timing chain components during strip-down.
02COMPONENT REPLACEMENT
Main bearings, connecting rod bearings, gaskets, seals, and timing chain components replaced as required.
03QUALITY CHECKS
All major rotating assemblies, oil pump, and cooling system components inspected for long-term reliability.
Typical Scope:
Main bearings, connecting rod bearings, timing chain components, gaskets and seals, oil system inspection and replacement of affected components
Starting From:
£3,200

JAGUAR AJ30 REBUILD VS REPLACEMENT VS USED
Rebuilding Your AJ30 Engine
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your Jaguar 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.
- Strip down & inspect
- Pressure-test
- Replace worn components
- 12-month unlimited-mileage warranty
Replacement AJ30 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 unlimited-mileage warranty.
- Supplied & fitted by our team
- OEM quality
- 12-month unlimited-mileage warranty
Used AJ30 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, especially given the known oil system concerns on this engine. Enter your reg below and we'll talk you through both options honestly.
- Low-mileage units
- Quick turnaround

Reconditioned, Refurbished or Remanufactured?
JAGUAR AJ30 RECONDITIONED 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.
→ Our rebuild service is exactly that.
JAGUAR AJ30 REFURBISHED ENGINES
"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.
→ Our rebuild service covers this.
JAGUAR AJ30 REMANUFACTURED 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, regardless of which of the two AJ30-equipped models you drive. AJ30 Reconditioned / Refurbished / Remanufactured / Rebuilt - Terminology Explained Rebuilt: Existing engine stripped, inspected and rebuilt to original specification. Reconditioned: Broad industry term; we define our rebuild as a full strip and rebuild. Remanufactured: Usually implies a defined restoration process; our rebuild meets this standard. Used: Existing engine from another vehicle; we can source and fit these. What Jaguar Garage Means by "Rebuild": Full strip-down, inspection, measurement, machining where required, replacement of worn components, reassembly, testing, and refit - with a 12-month unlimited-mileage warranty.
→ That’s consistent with what our rebuild service delivers.
