After a family 4x4 wagon, and no matter where you go patrol is always mentioned.
I didn't buy a patrol with the ZD30 from a lot of stories I heard on forums but now that I want to get into the more 'hard-core' 4x4 scene patrols seem to be the go. But like I said heaps of horror stories, then there is NADS which I'm sure would fix most engine problems but should I even consider buying a 2004 patrol with 180xxx that has never had these preventative measures? There are patrols still fetching top dollar with near 200xxx for over $20k
Would you guys consider buying one? Budget is about 20-25k

Shop around for a good price Zimbo - there are a lot on the market. We have a 2002 model and it is good vehicle with NO mechanical problems. They aren't all Hand Grenades.

Probably on about 190,000 now Zimba. We got EGT and Boost gauges. If they go up, slowing down cures the problem and the motor stress. We towed our heavy caravan with it including all over Tasmania. As, being auto, it is rated to tow 2.5 tonne we had to get a different tow vehicle to be able to load the caravan for big trips.

I owned the supposedly worst of them, a 2000 model. Did 195000, no engine issues whatsoever. The thing was running as sweet as brand new when I sold it. Occasionally wish I had kept it. Wish they'd put a bit more powerful diesel in the current one. I'd buy one.

No mods. When it first came out the sump only held 5 or 6 litres of oil. They did an in service mod that increased it to 8 litres or so.

Only thing I did was change the oil every 5000ks. It towed a caravan for the majority of the time including two round aus trips.

If Nissan would just replace the 3.00litre with a more powerful diesel they could corner the serious 4WD market. There's nothing around at the moment that's worth buying.

No I would buy a GU 4.2 diesel which you can get for your money from 1998 to early 2000's with anywhere from 200,00 to 300,000 because the motor will just keep going. My current 1993 4.2 GQ I purchased over 4 yrs ago with 350,000 now has 433,000 and still running fine no timing belt to muck around with either.

I would love the 4.2 but in the years I have been looking none have peaked my interest, so pricey also

It can take a while to find the right one but there are quite a few out there in your price range and you have to expect for the money it's going to be in used condition.

They still go up , but at a lesser rate. (A 2014 model last week)

But I'd do your sums Zimbo - I'm a long way in front with my 4800 Patrols and its a so much better 4wd and sports car all in one !



P.S. Talk about horror stories , I was with a group last week who insisted that D4D's go up more frequently.
I never put much credence in these things without reasonable proof though and the fact that someone might detail 1/2 a dozen engine blow ups really does not mean much unless you know things like the overall expiry rate.

Counter Intuitive isn't it Batts.

Until you look into it and find out they have a 48 degree rollover angle (same as a Cayenne) and some 6 degrees better than the most popular 4wd wagon out there.

Problem was the diesel versions never had the power and brakes to make use of it.

12 years now since they came out , and when they coupled 185kw engine bigger brakes and could hit 200kmh in the manual version - well they finally took 4wd of year off the cruisers and no-one really cared about the fuel use after they test drove them.

You could lower it and do modifications to the motor that increase its output to around 2,000 hp which is achievable and that would help in a straight line but it's not a sports car because it would be so unstable unlike a sports car at higher speeds. Your roll-over angle will help while your off road on uneven terrain at lower speeds but if you try and corner like a sports car on the road your 48 deg roll over angle will not help you as you're rolling down an embankment because the weight transfer of your 2.5 ton plus vehicle push it off the road. Power isn't everything it just helps in some places and gets you there faster but at the cost of burning a lot more fuel than a diesel.

Alot of the guys down my way are putting the 4.2 out of the gq into a grenanded gu 3.0.
Engine mount plates from Nissan and bell from the gq box on to the gu box. Couple of other mods, and your going again...

You could also do what the "TONY" project did and put a Toyota 1HDFTE in the Patrol and supposedly have the best of everything LOL

Zimbo Fox

I had one for my work and it has been replaced with a 76 series Landcruiser Workmate. Wish I still had the patrol. Much better vehicle.

Not all ZD30s fail. A lot of people get a good run from them. A friend of mine had one that failed. He put a chev V8 diesel in it and loves it.

One of the locals in my home town had problems with his hi-lux. New motor under warranty. Whatever you buy you can have problems. Toyotas have a well earned reputation for reliability yet I still see a lot of them on the back of tow trucks.

Whatever you buy there is some risk, especially when buying secondhand.

ZF - There are still excellent older 4.2L Patrols out there, you just need to look on an intensive basis.
Often the ads are stupidly worded in the title and the seller denies themselves the exposure to the market that they would have if they used a better title.

Here's a 98 model 4.2L powered gem with only 132,000 kms.

'98 Nissan Patrol 4.2L for sale

So guys I have found a 2000 series I ST 4.2TD Patrol with 250xxx on the clock, one owner and he is a mechanic. It's near immaculate, dosnt look like it's been off road too much. Sound good? Only thing is its the series one with 90kw where as series II bumped up to near 120kw and torque is also down on the series I compared too series II, or would it be easy to pick up that extra power?
Thanks

Zimbo

I sold my 2000 series II 4.2 Turbo Diesel 2 years ago. Still wish I had kept it. Very reliable vehicle. Lacking in power and thirsty compared to my present vehicle.

I have checked the power of the Series I and it is 114 kw and 330 nm. The series II is exactly the same.

The 2.8 TD which was replaced by the ZD30 put out 90 kw.

Yeah the standard diesel had 91 kw and the turbo 114 kw and it would be very easy to increase that by adding a snorkel and complementing that with larger exhaust this will see an instant improvement in fuel econ and power. If you want a bit more power you can find a reputable diesel tuning company to tweak the turbo up just a couple of pounds. As you may be already aware patrol motors and drive lines can handle massive increases in power and torque figures without compromising reliability so minor mods like I have mentioned have been quite common over the years.

It's the non intercooled 4.2, everywhere I look it's 90kw and 330nm, same power as non turbo just more torque, after driving it the power did not phase me, was fast enough.
Still though is it worth over 20k?
