How long to modern 4cylinder toubos last.

Sorry the runner had a 22r Motor
Cheers Pete

Plenty of 4cyl TD motors won't last 400,000k. They die from other causes before they wear out, especially cylinder head problems, even though they are well serviced. Doesn't seem to happen to 6cyl TDs like the TD42 and 1HD-FTE.

But most normally aspirated diesels last well.

If its a 3.0 litre Nissan then it won't last to long at all.

Who really cares ????



Fair dinkum.....IF you keep the 4x4 that long , you won't know if it was engine wear.....valve wear.....fuel pump failure etc..etc..

To buy a 4x4 now a days expecting big mileage is a bit of a lottery.......and don't say because it's a T**ta will guarentee anything !!

Hi All !

For what it's worth

The single biggest issues with modern motors, that I can see is that a some people do their own servicing, ( that's great ) and it's always been the case.
But here in lies some of the problems.... Modern motors want a specific type of oil, to get the circulation happening, properly..
The recommended oils are listed in the "owner's Handbook", and should be rigidly adhered to..

There is no future in using any oils, !.. as this will "bugger up", the circulation, or allow corrosion of the aluminium bits, inside..
Cannot grab any oil, just because that oil is on special

Other thing is the frequency of oil changes, and replacement of parts..I used to do the Navara every 10,000 km with a synthetic oil, and after speaking to a few mechanics, when towing change the oil every 7,500 km ....

Not sure what I would expect out of the motor, as I do not own it any more, but 350-400 thousand, would be in mind..

As for the turbo, I do know of others that have issues, but everything worked well in the Navara, with max boost, under load, on a dyno, was 16 PSI,,,and problems could be linked back to driving habits, type of oils used, and general lack of servicing/fault prevention....

By the way I have to agree with that the Rodeo 2.8TD motor.. They seem to go forever..and after I found out that the ZD30 Nissan motors were giving lots of drama's, I was trying to work out a "what if" mine went bang,, how was I gunna put a Rodeo motor in My Navara,,
Fortunately that never happened.

Have 3 mates all have had Nissan Navara's and all had turbo problems before 200,000km - latest was replaced at about 70,oookm.


Try to sell mine before 200,000km as well Pete, main reasons are that by then they have usually had several years of hard work and are just getting a bit loose everywhere and clutches need replacing etc.

Trouble is the current car still has better to power to weight ratio than newest entrants into the market and better 4wd credenials - so what to do !

I think that one reason why you won’t see extremely high k’s from a late 4 cylinder turbo diesel is the due the emission controls and high boost that they run for emissions.
Your EGR valve will clog up and fowl the engine long before the rings and bearings wear out and the oil in the intake system from excessive crankcase blowby will shorten the life of the turbo and affect your mixture control system.
It will be interesting to see how the later Nissan and Toyota sixes fair having EGR also, but there are so many 4 cylinder turbo diesels available today and they will be the subject of scrutiny.
They’re all good motors, but unfortunately some of them will be let down by inferior electronic controls. I think that as technology progresses, there will be further improvements to their control systems and perhaps we’ll see higher k’s again some day.
