Has anyone experinced long term problems with the engine in the Nissan 2.8L GU? Mine is still under warranty and I am wondering about the life of the motor. Has the 2.8 motor been used in any other nissan models?
Thanks Jim

As a specialist 4x4 mechanic I would just like to say , maintain it by the book with carefull attention to cooling system and engine oil changes.This engine has an alloy head and will not stand any overheating and must have correct coolant.Indirect injection means contamination of engine oil with soot from inefficient combustion so 5000k oil changes are essential.Look after the above points and you should get 4000.000k from the engine at least. Regards Ken.

In my opinion the 4.2 Nissan turbo and non turbo is the more reliable engine it is 'low tec' and has proven itself over nearly 15 years of production, however it is also indirect injection and needs to have 5000k services. Regards Ken

Charl. This one is going to take a bit of thinking about.Efi on petrol engines has been around since the early eighties and was initially just an add on to the existing engines of the day, things have moved along since then and engine design has gradually kept pace!Efi on diesels is relativly new and seems to be driven by the need for clean emissions as was the case with petrol.Small capacity high output diesels are a european thing brought about by engine size regulations.The 4.2 and 4.5 Nissan engines are old tec engines with hi tec efi systems attached I think that they are both good honest performers The new 4.8 is something else again with increased capacity and multi valves time and kilometers will be the judge of this one. Regards Ken.
