The 5.0-litre supercharged V8 turns a two-and-a-half tonne Range Rover into a sports car. Owners adore it. Technicians respect it. It has a set of well-documented weaknesses that, once addressed properly, leave you with an engine that runs beautifully for years.
1. Supercharger nose bearing
A whine that rises with engine speed, most noticeable at idle with the bonnet open, is the supercharger's front coupling and bearing wearing out. The fix is a nose cone rebuild with an upgraded coupling. It is not a supercharger replacement.
2. Coolant crossover pipes
The plastic pipes running beneath the supercharger become brittle in heat and crack. The symptoms are a coolant smell and a level that drops slowly. Access requires supercharger removal, so we fit aluminium replacements that will never fail again.
3. Timing chain tensioners
Early engines had tensioners that could lose pressure on cold start. The updated tensioners and guides cure a rattle that, left alone, can cost the engine.
4. Water pump
A weeping water pump is normal wear at 100,000 km. We replace it with the thermostat and belt at the same time to avoid repeating the labour.
5. Oil consumption and PCV
A clogged crankcase ventilation system raises oil consumption and can push oil past seals. A PCV service is cheap and often transforms consumption.
Every one of these repairs is carried out in-house with genuine or upgraded parts. If your V8 is showing any of these symptoms, message us for a diagnosis before summer arrives.
