Expert care for naturally aspirated and supercharged AJ133 engines.

Flagship AJ133 V8
Specialist AJ133 Care
The AJ133 5.0 litre V8 powers some of the most capable Range Rover, Range Rover Sport and SVR models built, in both naturally aspirated and supercharged form. An engine at this level of cost and performance needs a genuinely informed approach, not a generic V8 diagnosis.
Owners typically come to us either investigating a specific fault, such as unusual engine noise, or weighing up rebuild costs against replacement. Given the value involved, getting clear, honest guidance early makes a real difference.

We explain exactly what drives the cost of AJ133 repair work before you commit.
Cam follower wear is one of the most widely reported AJ133 issues, where the follower surface degrades and can send metal debris circulating through the oil system. Left unchecked, this can damage camshaft lobes and turn a contained fault into a far more serious rebuild.
Where cam follower wear is found, we look at fitting DLC-coated followers rather than standard replacements, since the coating is designed to resist the wear pattern that caused the original failure. This is particularly relevant on supercharged variants, which place additional load through the valvetrain.
Beyond cam follower wear, we also check timing chain condition and general engine health as part of any AJ133 diagnosis, since these factors affect whether a targeted repair or a full rebuild is the more sensible route. We'll always explain that reasoning clearly before recommending either option.

Request A QuoteIs the Range Rover 5.0 supercharged V8 reliable?
It can be dependable with attentive maintenance, but cam follower wear is a well-documented issue across the AJ133 range. Reliability depends heavily on service history and how quickly early symptoms, such as ticking noise, are investigated before more serious damage develops.
What are the most common AJ133 engine problems?
Cam follower wear is the most frequently reported issue, sometimes leading to camshaft lobe damage if metal debris circulates through the oil system. Timing chain condition is also worth checking, particularly on higher-mileage supercharged variants under greater mechanical load.
Which Range Rover models use the 5.0 supercharged V8?
The supercharged AJ133 is fitted across higher-trim Range Rover and Range Rover Sport models, with the Range Rover Sport SVR receiving the highest-output performance tune. Naturally aspirated versions of the same engine are fitted to entry-level V8 trims.
How much does it cost to rebuild a 5.0 V8 engine?
Cost depends on the extent of cam follower or timing chain wear found during diagnosis, along with whether a targeted repair, rebuild or full replacement is appropriate. We assess each engine individually and provide a clear, itemised quote once diagnosis is complete.
What's the difference between naturally aspirated and supercharged versions?
Both use the same 5.0 litre V8 block, but the supercharged version adds forced induction for significantly higher power output. This extra load makes the supercharged variant somewhat more demanding on components like cam followers and the timing chain.
Are DLC-coated cam followers worth fitting during a rebuild?
In most cases, yes, since the coating is designed to resist the wear pattern responsible for the original failure. Fitting standard replacement followers without addressing the underlying cause can lead to the same fault recurring later on.
Do reconditioned Range Rover 5.0 V8 engines come with a warranty?
Yes, reconditioned and replacement AJ133 engines are supplied with warranty cover. We'll confirm the specific terms for your engine and vehicle before any work is booked, given the value involved in this engine.
What areas do you cover for Range Rover V8 engine work?
We're based in Grays, Essex, and regularly support customers across Essex, London and the wider South East, alongside UK-wide enquiries for engine supply and fitting. Contact us to confirm availability for your location.
