Jaguar AJ16 Rebuild Components
Timing Chain
We inspect and replace timing chain components as standard during a rebuild.
Bearings
We replace main bearings and connecting rod bearings as standard during a rebuild.
Gaskets & Seals
We replace all gaskets and seals as standard during a rebuild.
Twin-Scroll Turbocharger
The AJ16's twin-scroll turbocharger is a key component that is removed, inspected, and refurbished or replaced as part of the rebuild.
Additional Inspected Components
Fuel injectors, high-pressure fuel pump, PCV system, timing chain tensioners and guides, and cooling system components are all measured and inspected.
Components drawn directly from VRF Key Components data. If your AJ16's exact ancillary set isn't covered above, we confirm the full scope once your engine is inspected — not guessed in advance.

JAGUAROUR WORKSHOP VIEW OF
THE JAGUAR AJ16
Built, rebuilt and tested by engineers who work on Jaguar engines every day.
Here's our practical view of the AJ16 across its 2 model applications.
Note: engine-specific case studies with real job details are not yet included on this page — they'll be added once a documented set of completed AJ16 rebuilds is available to draw from, rather than filled with placeholder examples now.
A TYPICAL
JAGUAR AJ16 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.
A full AJ16 rebuild involves stripping the engine down, inspecting the crankshaft, cylinder head and timing components, and replacing worn bearings, gaskets and seals with updated OEM-specification parts (Inline-6 (I6), 4.0L (3,980 cc), Petrol).
Typical Scope:
Timing chain, bearings, gaskets, twin-scroll turbocharger inspection/refurbishment, calibration of fuel injection system
Starting From:
£2,200

ENGINE REBUILD COST

Exact pricing depends on the condition of your existing engine and the parts required — submit your registration for a fixed-price quote within 30 minutes.

REBUILD VS REPLACEMENT VS USED
Rebuilding Your AJ16 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. This is the option most AJ16 owners choose.
Replacement AJ16 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.
Used AJ16 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.
MERCEDES-BENZ AJ16
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.
MERCEDES-BENZ AJ16
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.
MERCEDES-BENZ AJ16
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 six AJ16-equipped models you drive.
