Landrover Discovery 3 (4L V6) - Timing chain tensioner

[Kevin H]

Thor,
Just as an aside, do you know why there is some prevalence for the 3.0L diesel engines in D4 to seize?

A friend here in Melbourne had his seize recently and remarkably Landrover replaced the engine free of charge (I say remarkably because he had done 173,000 km!). He had to pay for the labour but he's very happy and relieved! He believes LR did this because he bought the car new from an authorised dealer and had it serviced by them, on time, religiously. The dealer made a "good will" claim on his behalf.

He now wants to know what he can do to avoid it happening again.
