Disadvantages of the Land Rover 306PS engine
Timing chain tensioners are the most well-known weak point of these units; the blower drive frequently fails and needs to be replaced here; valve seat loss and a blown cylinder head gasket occur infrequently but occasionally;
Here, fuel injectors and throttles need to be cleaned on a regular basis;
A small resource separates the pump from an additional cooling fan.
