Re: Oil on the air filter and Oil Separator Leaks (T31 Diesel)
58phil; sure, go ahead and show them this thread!
To update my post of 4 April, Lander Nissan replaced the EGR valve under warranty. They showed me the old one - the one-inch diameter port looked completely blocked with soot and they told me it was not repairable, it was not possible to clean it. I did not argue with this as they were replacing it under warranty!
I have now done 1500km with the new EGR valve and software update. The engine performance is noticeably better, it spins to the redline more easily but in normal driving it is often in a gear higher than before (it is the auto gearbox), happy to spin at 15 - 18k rpm. So, more torque below 2000 rpm.
The fuel economy before the repair was 8.3L/100km over about 5000km. Now, 1500km since the repair: 7.5L/100km!
Lander told me that they do not expect the valve to block again because of the improved version of the EGR valve and the software upgrade. They also told me that they believed that the previous owner must have used the car around town but with few long runs at 100km/h.
So I am happy with this, and my experience with Lander Nissan was very positive.
Cheers,
Bill

Re: Oil on the air filter and Oil Separator Leaks (T31 Diesel)
I have just had my 20k service done, the oil was on the airfilter, not too bad but the mechanic cleaned out the box and fitted a new filter. He reckons most Euro turbo diesels have the same problem.

Re: Oil on the air filter and Oil Separator Leaks (T31 Diesel)
Probably have oil on the MAF (Mass Air Flow) sensor. It should be located on the intake between the air filter box and the turbo. You can buy specialised cleaners from auto parts stores. It only take two screws to remove it for cleaning.
