This video shows a typical valve cover failure on a Range Rover Sport 3.0L TDV6.
This malfunction occurs on all versions of the 3.0L TDV6 engine, which is installed on a wide range of models.
A symptom of a broken cover is the inscription "Engine power limitation" and lack of traction during acceleration, as well as black smoke from the exhaust system.
Errors in the on-board computer are recorded by mass air flow and by lunch mixture.
For this diagnosis, it is necessary to check for errors, remove the decorative engine cover and increase the engine speed to 2500 - 3000 rpm, examine the operation of the intake manifold system. If a crack occurs and air pressure occurs during the occurrence of revolutions, then the intake manifold must be replaced.
