Q
I have a 2009 Nissan Navara 2.5 diesel and I am concerned about the stories I have read about these motors failing anywhere from 60,000 to 120,000 km. I have also read about the timing gear failing. Have you heard anything about this and if it's true what can I do to prevent it?

There are reports of engines failing, but those that have appear to have failed because they weren't serviced by the book. It's important to religiously service the Navara, and use the Nissan recommended oil. The failures we have heard about are mostly failures of the camshaft, cam timing gear etc that have led to more serious damage. It's believed the initial failure of the cam or cam gear is due to a lack of proper servicing, leading to blockages in the oil passages feeding the top of the motor.
