3.0lt turbo diesel reliability

[esp22]

Which year did the 3.0litre turbo diesel strat getting reliable?Thanks

[drew4130]

the year is still coming

2003 - 2006 still have over boost issues but that is easily fixed.
No more turbo lag.

unless your talking about a navara zd30...? im not sure why gu people are not buying these engines to replace their gu zd30..?

oh for those that want to know, navara's have a solid flywheel, i don't care what you have been told, i just pulled my gearbox out and the engine out of the wreck and they were both solid.. 02 model dx and 05 model st-r.

cheers mark.

how much kms should i expect out of a 2003 GU III ST 5 speed manual 3.0 lt turbo diesel before i need a rebuild?Any other problem that ma come up

This would be a much better option, sure they aren't as powerful as the Patrol version, but simply intercool and up the boost with the standard wastegate Turbo and your off,

can't be that hard to swap over

It wouldn't be any better then the patrol engine. the ONLY reason they don't blow up AS MUCH in navs is because they are less stressed with less power in a lighter vehicle.

up the boost and put it in a patrol and BOOOOOMMMMMMM there goes your nav engine.

I would not necessarily call them stressed. Mine doesn't rev much over 2200rpm around town, doesn't boost more than 10 psi (around town) and egt's are typically around 250 degrees from behind the turbo. They fail because of some inherent design flaws with the ancillary controls like the MAF sensor. The ZD30 in the Nav's are not without their problems, but don't seem to be suffering as much as the Patrol engines. Probably because they use a traditional waste gated turbo and no MAF and as a result, different ECU. If you really want to know more information refer to this link: http://www.chaz.yellowfoot.org/zd30_engine_problems.htm. Chaz also lists the mods you should do to prevent the hole-in-piston type failures. So beware when buying second-hand.

the day they went common rail , as much as i hate to say it im yet to see a failure myself of a CR one altho fuel pumps etc is a different story still its in the back of your mind every time you drive one (nissan tech) is this one going to be the grenade, i owned an early series one and it did the hole in piston trick. someone else posted before about the solid flywheel in a navara , yes correct only patrols are fitted with a Dual mass flywheel with a zd30 , navara has a solid definately

Wrong. the navara zd30's do not have a MAF, no variable vein turbo and the have a coating on the pistons. They are not that much under powered than a patrol zd30 , although i do agree they are a little lighter than a gu but not that much..

how much kms should i expect out of a 2003 GU III ST 5 speed manual 3.0 lt turbo diesel before i need a rebuild?Any other problem that ma come up

most blow up ~70,000-120,000klms...

what bogged is saying is that there is not defined blow up point or rebuild point for a patrol zd30.

the length of time you go without cracking or melting a piston is entirely dependant on the MAF's lifespan (which is crap) and fuel supply being clean and uninterupted.

Cool, so I've already beaten your odds ay and I do not think that I'm in the minority

Get yourself an EGT gauge and it won't blow up at all cause you can keep an eye on what the electronics are doing.

I would guess a rebuild due to mechanichal wear would be past the 500 thou K mark based on what people have reported when pulled down at 250 thou.

Unless one of your injectors starts dripping instead of misting.

But that could happen to ANY direct injection/common rail diesel anyway couldn't it.

Do you think you would guess something was wrong with less power and an increase in fuel usage?

You would need to know your truck well but that is how I spotted my failing MAF, first with increased consumption and later on it was developing a flat spot (had no gauges then).
