When did they stop selling the patrol in the uk?

If I were to look for a late one, which is the best bet?

Not immediately planning to swap but towards the end of the year it'll be quite likely. I always take my time doing my homework and looking around :thumbs


Cheers :thumb2

Dave you can still buy a brand spanking new Patrol if you've got the cash. Latest to date is Y61 Mk4.

Y61 1998 to 2000 is the 2.8TD6. Straight 6 130bhp standard. 8 valve, SOHC belt driven. You can easily increase engine power on these with a tuning box:augie to 170ish without issues:clap

Y61 2000 to date 3.0ltr 4 cylinder 160ish bhp. 16 valve DOHC, chain driven You can also easily increase engine power on these with a tuning box:augie

There were some problems with the early 3.0ltr engines up until 2003 after that they sorted the engine. The problem was rumoured to be due to the variable vane turbo over boosting and the engine going bang. Nissan changed a few engines under warranty, but never fully disclosed what the problem was

4WD system is beam axle at the front and rear axle with difflock. Similar to T2. Normal driving is 2WD then 4 hi and 4 lo
Suspension is coil springs all round, no torsion bars:clap and rear anti roll bar can be electronically disengaged when on the ruff stuff.

You can get hi trim spec, ie leather etc or low trim, what ever your after.

Thanks Jocky, I can say with confidence a new one will be out of my budget

Having seen a few here and there for sale I would be going 54-55 plate ish but with an open mind.

I like to do my homework, I was looking around at 4wd's to pull the van for about a year before I got this T2 :lol:lol

cheers :thumb2

I don't think it was anything to do with the turbo. It was an overheating problem due to inadequate oil circulation that resulted in pistons 3 and/or 4 melting.

Although they made some changes to oil spray patterns to reduce the likelyhood of pistons melting, the real fix is supposed to have been merely a shortening of the dipstick (yes, seriously!!!), which increased the oil quantity by 2 litres (which is why they now use 8.2 litres on service, rather than 6.2 litres for the earlier engine).

There is a lot of info about this on the Australian Patrol owners website.

I have an 05 plate 'Troll. It's a fantastic towcar. You need to be sure, though, that you are comfortable with it's fuel consumption. I get (very) low 20's footling around near home normally and 18-20 towing a 1500kg caravan (mostly motorway). For long motorways journeys solo at less than the legal limit, you'll get around 28mpg - which is also quite typical for long runs on A roads too. Expect never to get as much as 30mpg no matter where you drive or how gently you drive it.

Dave, there are rumours going round that there is an all new Patrol out next year. I've seen pictures and it don't look nice:doh

One thing I've noticed with the later Y61's on the market is there seems to be loads of auto's and not so many manuals:nenau.

I'm planning to keep mine for a couple of years then get another Patrol Y61 or Pathfinder.
The thought of the £495 road tax will probably make the couple of years stretch to longer:augie

Hi Andrew, I'm not getting into an arguement about the problem
I've read all the oil stuff, the turbo over boosting, high exhaust gas temps and the pistons melting on the aussie site.
Only trying to point out there was problems with SOME engines between 2000 & 2003:nenau

Great cars BTW:clap

Hi Jocky
Buy a commercial or put a magnetic sign on, go self - employed it don't matter for what take up carpentry or something then the tax is "only" £185

Still got to be a strictly commercial variant on the V5 tho surely to qualify?

Beats going to the garage and asking for a longer dipstick.... as this one doesn't reach the oil..:lol:lol

I've read that, but don't think it was the full problem. If it was, all early 3.0ltrs would have been grenades.:lol

Why shorten the dipstick:nenaujust move the min & max points:lol

Davemudd has been telling me about his turbo boosting and exhaust gas temps as he's put a temp gauge on his to keep an eye on it.

 

[davemud]

Hi u guys very good post
Jocky as you know i have been moding mine since I got it Mainly due to the fact that it was much slower than my 2003 3.0 T2
I never had any issues on my t2 had it 5 years and covered and 120k
We took it to Spain and back with my caravan on the back 5 times but it was always well serviced that's why i got another 3.0L Auto

Performance Mods to date
3 guage set up as recommend by the Patrol Forum I can see oil pressure, Boost presure and Exhaust gas Temp post turbo
Injection mod from diesel Bob (as all Injection mods are nearly the same just increase fuel timing via the fuel pump)
Full 3" s/steel twin box exhaust System (built by me) as every one i asked quoted silly money
Single 17" main cooling fan removing viscous standard one (easy to refit if viscous if towing in hot climates ) Makes less noise and more free reving
Single 12" Inter cooler fan manually switched

The Only problem i have found to date is the over boost issue after fitting the bigger exhaust, u can see on the exhaust temp readings how much cooler it runs
but if you start to feed in to much fuel the temp starts to go back up,
The over boost issue is not a real problem i have been working out the best pressure to run at, to achieve the best performance.
Rolling road is what i would like to use and set the car up on there but non are available locally to me.

The Patrol Is one hell of a mota will literally go any where you ask it to, mine has seen some very steep hills, deep water, and loads and loads of Mud cant really fault it at all. :thumb2

Just one Real pain in the ass is parking as all parking spaces seam to be getting smaller but if you find a nice open car park every one keeps away :lol:lol

 

[Timbo_1975]

As far as EGT's vs fuelling vs boost pressure is concerned- yes you really need a rolling road to set it up nice for max power/torque, but as a base point:

1) pre turbo 1100deg F, post turbo 850 MAX continuous EGT.
2) boost pressure- enough to clear the smoke. More boost pressure = higher drive pressure = higher egt's. More fuel does NOT necessarily mean higher egt's.
3) lower back pressure from the exhaust = lower egt's = better.

Does your VGT have any control from the ECU ? It ought to be self compensating. Where in the rev range does it overboost?

 

[davemud]

Hi timbo
the VGT is controlled by the Ecu currently have fitted a Daws valve to limit the vacuum pressure to 18psi

It over boots under high load at about 3k then the ecu shuts down goes in to limp mode, just lift you foot of the pedal and apply the power again
