Nissan Patrol 2000: Both the original and replacement engine failed

Asked by Jacquie May

In December 2000 I bought a new Nissan Patrol 3.0L diesel. It was serviced regularly at Nissan dealers and I often pointed out difficulties in starting the car and what seemed to be lack of power. In October 2003 the engine blew up -- apparently the compression in No. 4 was way down. Nissan replaced the engine with a new one, but two weeks ago the replacement blew up . . . apparently for the same reason. I know the car lost total compression and, soon after, clouds of black smoke appeared. Could you please supply me with some information? l want to avoid being in the situation of having another replacement engine blow up.

Many reports from the trade relate to the 3.0-litre diesel Patrol, and they don't make pleasant reading. It seems the motor suffers from head problems (head gasket leakage and cracking) which was fixed with a thicker head gasket that lowered the compression slightly. It also suffers from an oiling problem, which can become a worry when the Patrol is driven at highway speed in hot climates. Nissan increased the oil quantity to overcome this problem. I would suggest you keep a close watch on your engine, and perhaps ask Nissan for some sort of extended warranty coverage. Smaller used-car dealers are taking extended warranty on any 3.0-litre Nissan turbo diesel they sell to protect themselves against a problem later on, which should give you some idea of the how they view the vehicle.
