2003 GU diesel - Gumtree (3.0L turbo diesel)

[Alex Roux]

We all know the TB42, TB45, TB48, and the TD42 motors are pretty much bullet proof, we all don't give enough credit to the ZD30 motor ( even I cannot believe I'm saying this, but the ZD motor has grown on me, like the TD42 has grown on Tinus ..... ). I assume the UN also had a spec on these motors for service as with the spec given for the other Patrol models and I presume Cruisers etc.

I suppose depending on how the motor has been treated will effect how long the motor will last. I don't know if after 150 000km, whether the block will need to be re-sleeved or just a quick honing. Injectors, well they would need to be replaced at some stage anyways I presume. I'm not sure what the life expectancy is on those.

The (sad) reality is that without having been managed by driving with an EGT, there is now way of telling the potential extent of cumulative damage done to date. In particular the cars of that generation (pre face lift) without an EGT installed I do not known" of one that lasted beyond 200,000, without extensive repair required.
