Land Rover 2.0 Ingenium Engine Rebuild
Common Land Rover 2.0 Ingenium Engine Failures
The 2.0 Ingenium diesel engines are a common sight at Dieselheads and are prone to a number of failures in all configurations:
204DTD – Range Rover Evoque, Land Rover Discovery Sport
During inspection we have found varying degrees of damage, some engines are seized and are often not repairable. In these cases a replacement block is required to create a reconditioned engine (engine surcharges). A number of times we have discovered failed turbochargers on both single and twin turbo variants, most of these examples are engines that have not been maintained with regular oil changes. The intake of oil causes the turbocharger to spin, rev up and overload the capabilities of the engines internals. The contamination of soot and particles from the plastic timing chain guides make their way down and can block oil feed and galleries, therefore components lose the lubrication they require (often causing spun bearings). Another area prone to lack of correct lubrication is inside the cylinders, in some cases we have found over fuelling injectors have contaminated the space between the piston rings and cylinder walls. Due to the difference in material hardness between these two areas, without ideal lubrication the piston rings create a cutting effect and it wears the walls as the piston travels down. Like most engine failures this can cause multiple following failures, as the piston drags the contaminated oil down through many revolutions this can in turn create the oil distribution problems listed above.
The Ingenium engine can also commonly suffer from timing failure, in these cases the timing chain can stretch or snap causing damage to rocker arms, cam carrier, vales and guides.

204DTA/204DTD Evidence Of Damage
Land Rover 2.0 Ingenium Engine (204DT)
In 2015 Land Rover released their own branded range of modular engines to replace the previous Ford variants like the 2.2 eD4, these platforms were produced to incorporate both petrol and diesel. The engines were designed for flexibility, the design allows for easier production of versions with fewer or more cylinders and the ability to be mounted transversely or longitudinally for 2 or 4 wheel drive applications.
The first diesel Ingenium engines used were fitted to the Range Rover Evoque, this was the single turbocharged 204DTD. This was also later fitted to the Land Rover Discovery Sport, both of these are transversely mounted. In 2017 a twin turbocharged variant was fitted to the larger vehicles in the line up, this includes the Land Rover Discovery 5, Range Rover Sport and Range Rover Velar. This is the 204DTA and is mounted longitudinally.
