Offroad-Express

Im waiting on feedback about an AA check on this 4runner 4sale

http://www.trademe.co.nz/Trade-Me-Motor ... 575889.htm

tjm bullbar
40mm bodylift
33tyres bfg's
front auto locker
2.8 with aftermarket safari turbo kit
snorkel
diff breathers
cb Radio
good stereo
Rear bars and hooks
side bars
Alarm
manual hubs
2.5 exhaust

it has new clutch and wheel bearings
If AA check comes back good I will be buying, I have a baby and need something that can be a daily runner and go okay offroad aswell, so i need 4door and that limits me to what I can get , as safaris and bighorns ect are a bit too big for me, I know its IFS but that will work on my side being a daily driver.
now I know ya can buy a nz new 4runner For about 5-6grand but ive calculated About $9,000+ wirth of goodies on this, and I would prefer to get one with work done.
and if i got the 3.0td model I would be looking at about t$9500 for a standard one, so thats not an option.
Petrol one im not interested.
and 2.4td Not keen as too slug n slow as i have an old 2door one currently.
What do yous think, reacon itl be powerful n a good combo for on road and offroad and holidays and baby puller.
Reacon its worth money or rip off?
when i get it ill be puting bracket on back for spare wheel and getting tubes for tyres and fitting my old man emu shocks off my 86surf (hopefully if they fit) probs a very small lift using 30mm spacers as 2" i reacon will be to high to run round in all day. and eventually a winch
any advice on if its worth this value is very appreciated
thanks

Please anyone reading this Consider the 4x4 sold as I'm 99% purchasing

This truck is at the airport as the owner works for Air New Zealand, I have looked at it several times as I walked past and it is very well maintained would be a good option for you

You're calculations for money spent on mods would be about right, but I would estimate quite a bit more than that), looks really good value for money, and would be a nice daily driver, nice truck
Those 2.8's are a bit sluggish (the turbo will help), but they seem to go forever, and are really cheap to run and maintain

Looks like a tidy truck ,

Does it have a cert for all the mods?
I noticed the rear bar is welded in place.

Does the speedo read correct?
Also noticed that it doesn't have a oil presure guage or volt meter

thanks for the replys its a big help. It is all certifyied.
I think with it not having a voltmetre and oil pressure will be as its NZ new 4runner model , They also have wind up windows and No aircon,
as far as i know there is no other difference other than the 2.8
anyone know if Shocks off a 86 surf will fit as i really wanna keep my old man emu's to keep cost down.

the front ones mite fit but the rear ones wont

You can go Holden rear shocks in the rear of the surf, I think this is what Matt4u has done right?

I did these on another surf also they bind up near the top on the one I did but they allow a lot more droop we did end up changing the rear shock mount a little but it was getting certed so didn't care.

We made new towers for the front Supralux style (but painted) and I have no clue what he got for us to throw in the front I think they were IFS 2wd Hilux shocks but don't quote me.

Holden rear shocks in the front, on Solid axle surf for travel.

Rear of LN130 and later surfs is a top pin, bottom eye set up, same as the front but a weeee bit longer.(quite a bit longer actually).

Crizpy your front shocks will fit in, just have to check the length.

for rear shock go for ones out of the front of a 60 serries cruiser. new ones will be abit stiff but slighly used should do an will be cheap. I put new ones in my surf and they where really stiff when not loaded up but it handeled really well on and off road with them.

The diff lock in the front will help out with the ifs. I have done very simila things to my surf and for having ifs it goes really well and handels great for a lifted truck. Price is on the high side but if it looks imaculate and you will struggle to find one modded that much and so tidy. I would go for it if you aren't interested in doing the work your self would cost atleast that to do it.

and some 4runners came out with all the electrics but i think it was only the top of the range v6 ones (like mine manual with crise control and elec windows and cumfyer seats lol)

got AA report back and bad news i think,
The compression is


1 2 3 4
535 410 460 530

leakdown
90% 40% 60% 94%


IS this bad news and do yous think i stay away from it, I understand compression looks okeyish but 2 and 3 slightly down.
But the leakdown test looks very bad, I dont exactly know what that means though.
please help.... was so excited

Leak Down Test

This involves pumping high pressure air into the cylinder and noting how quickly it leaks out on a gauge. The leakage rate should be very low if the rings etc are in good condition. Most garages have leak down testers and it might be worth having this done if the compression test shows a problem but you aren't sure where it lies. During the leak down test you can also listen for where the air is escaping and this can pinpoint the problem to a valve, gasket or ring fault. If the leakdown test shows no fault but the cranking pressures are low then it must be a cam lobe or cam timing type of issue. Copyright David Baker and Puma Race Engines

Doing a compression test as a first step whenever there's an engine running fault can save a lot of time in the long run. Plenty of people have struggled in vain to find an ignition timing or carb fault to try and cure a rough idle or lack of power when there was nothing wrong with those items in the first place. Nowadays with complex engine management systems and electronic everything, it's easy to fall into the trap of assuming an engine fault must be due to something horrendously complicated in a little black box somewhere. As often as not the answer is much more simple than that. Mechanical things go wrong much more often then electronic ones after all. The motto is "when in doubt, check the basics first and save the panicking for later".

Personally I wouldn't touch it at that.

Yuk, i personally would be thinkin about walking away from it, or at least presenting the comp/leak down data to the seller and making a significantly lower offer on it.

Being a 2.8, it will probably run like that for ever and a day, but due to the fact that you now know there are either glazed bores, poorly seating valves or worn rings in at least two of the cyclinders you don't want to be paying top dollar for it.

Remember that overhauling a diesel is expensive, about $6000 for a full rebuild on a Nissan TD42 as found in the Safari's.

First up, ring your toyota dealer ship, or drop in there with your data and talk to one of the service guys, they will let you know what the acceptable difference between compressions is for that motor.

Talk to someone about getting it reconditioned, and find a cost first. Diesels as said above are not cheap to recondition, once you have and idea on the recondition cost you can come up with an offer.

It is up to you but it will cost a lot more to recon than you would think but if you give him the info (cost of rebuild and the leak down test info) and then give him a price he may look at it all and say yes if you still think it worth while.

I have made contact with him , he says he talked to a diesel mechanic and showed him the results he says that it sounds like they havnt turned the fuel off when doing the compression test so #1 and #4 are actually too high and #2 and #3 are in spec.
I replyd and said . okey but leakdown results would still be that same wouldnt they?
he replied with
Yes but a leakdown is not the best test because you dont know where the pistons are located.

im not convinced , im going to call a diesel mechanic myself , Ill be saying I will not buy until another compression test is done by a profesional is done and given the ok.
but if a leakdown test would be that unreliable and show 40% why would they be so important , I read that 80% is the limit and anything under could require a repair.

Compression and leakdown are two separate things.

If there is liquid in the cylinder there will be more compression (liquid doesn't compress)

The leakdown test is there to see how much wear there is this wear in rings and cylinder bore is the bit you need to recon it for the leak could even be a small crack in the head, without pulling it down it would be impossable to tell even for a mechanic, they can only say what they suspect it is and judge from experience.

thanks for all the info its a big help.Im going to get a second oponion through a diesel specialist , and have him do compression and leakdown if the owner agrees .
not willing to buy unluss im %100 sure the motor is a good one.
I talked to specialist here and he said AA may of done a crap leakdown test not closing the exaust valves and turning motor to get the highest reading.
what do yous think about leakdown results?
what Percentage is a Good result and worth buying.
and what percentage would ya say dont touch it?

Speak to Diesel Services Limited

150 for leakdown and compression test, they know what their doing...

You're right, he's a workmate of mine at the airport. I always thought he looked after it pretty well, but seeing those results... Does look good though lol

okey so he has rechecked compression and the result was the same as AA check, So based on compression would yous say It sounds okey enough or do ya think I could be buying a problem,
as far as leakdown goes he doesnt seem to cooperate much to take it in for another leakdown.
he said that compression must all be above 280 and that They are all ok just a bit of a varience between them.. what efect would this have on the motor running with a varience and reliability in compression.

Variation in compression usually means there is a weak or poor seal somewhere this could be a valve or ring's the leak down test is the most important and costs more to do, It also if done right can tell you more exactly where any issue is.

Personaly if you want to get a leakdown test I would get it done by Diesel Services you can also call the AA and ask who did the leakdown test if they say diesel services (they do a few of them for other companies) then you know it is right, I would also go in to diesel services with the leakdown test and compression report you have now and ask them what they think, if they bring out a long pole then you know, your own independent expert looking at those results would be better than someone elses expert .

Uneven compression and bad results on the leakdown are not a good look I would keep and eye out for another one, and spend less buying it and set it up over time.

Get one install a locker front and rear and some bars and wait till you outgrow it and need a landcruiser or it becomes a play truck and you go for an exo, SAS, longfield axles, Dual cases, flat belly and put a 3 or 4 link in the back end...

everyone is different but reconditioning a diesel is not a cheap exercise unless you can do a lot of the work yourself and buying something with a questiopn mark over it you will never fully trust it for a long time, and then when you do it will let you down.

Edit to read better

The compression should be within a certain band between all of them for it to be ok. Based on the results you've had, I would leave it well alone. My motor had results simair to that and to recon it was going to be $5.5K (done by Diesel Services)
