Toyota Surf

I've had a 1994 non intercooled turbo 3litre Toyota Surf for some 6yrs or so now, it's coming up to 159thousand kms, had it since 70kms
It' hasn't given me any trouble but Dinos thread got me thinking , maybe I should spend some money on it to
help avoid this cracked head thing people talk about
I am not exactly handy as a mechanic, I do know that if you turn the key on and it doesn't go then there is probably something wrong.

It has a 1KZ-TE motor is Auto and as I said neary 160th kms.
I've been told it has the bigger radiator. I've some questions perhaps the more knowlegeable could help with

1- how do I know when the injectors need done and should they be done about now.
2- would fitting a proper snorkel be of any benefit, if so what type is best.
3- I'm fairly certain my LSD doesn't work and have had the oil changed but it still doesn't seem to go, when I have it in normal two wheel drive and one back wheel is off the ground it goes nowhere , the wheel off the ground just spins, I have to put it in 4x4high to get the front wheels to drag me forward.
Do I actually need the LSD to work?
4-would fitting a better exhuast help avoid the head cracking, if so what should I do.
5- Anything else ?

I've serviced it every 6mths since I've owned it regardless of the amount of kms I've travelled and it has had new filters every 10thou.I fitted a trans cooler the day after I bought it and it has a turbo timer which I use.
cheers.

Your lsd won't work if tire is off the ground. It just puts a tiny amount of power to the other wheel. They tighten up as power is put threw the diff so need some traction on both wheels.
At those kms its probably pretty worn. No you don't need it and its unlikely to shit itself.
Old school rule of thumb was injector service every 100tho k
Dunno about electronic injection but it would probably like having them done.
Exhaust and snorkel won't hurt.
Clean out radiator and air con radiator.
Maybe run a flush threw and replace coolant.
Keep an eye on gauges when driving.
Would have thought if it was goin to crack head it would have by now but Im no expert on those motors.

Injectors every 100,000 ks
Does allow for clean air if driving dirt roads regularly.
Toyota LSD's are shit, complete shit. Fit a locker.
yes, as long as you fit a nice dump pipe from the turbo also - getting heat away from the motor always helps.

Thanks Guys
I will print your replies out a take to my garage
Coolant/anti freeze is replaced every 6mths
will investigate a snorkel
and see someone about getting the injectors done and the rest.
ta.

The 3lt motor should be sweet for 400,000 k's with out any major issues .
Wouldn't worry about LSD,problem solved when you lock the front diff;in.
The big exhaust is a definite plus & the snorkel will as said be great on dusty roads
nothing gonna kill you engine performance quicker the lungs full of gravel dust.
A bottle of Wyns injector clean every 6 months keeps thing working ,as does
putting good quality oil in the sump ,cheap shit gonna cost in time .
Turbo's don't like cheap oil apparently ,he said $1500 later .

Tell me more about this diff lock thing, how does it work, and front or back or both?
and ARB snorkel?

A diff lock works in the diff you put it in. Ie usually rear but can also do front.
You can get auto lockers, air or electric selectable lockers.
With front and rear locked you will keep goin forward till some thing breaks, you fall over, or all 4 wheels are spinning .

Unless your contemplating serious 4wding i wouldnt bother with the expense.

thanks VC.

Mates surf with rear Detroit auto unlocking diff(normally locked unlocks for corners(sometimes:D))

Fitted ARB to my last HiLux. Fuel consumption got better more torque down low . Noticeable differences as it must help it breathe better
The air intake original plastic from under the guard chokes the shit out of the air intake . You won't regret it

Excellent, cheers Happy

ARB snorkel will eb overpriced as shit, go get one of trademe for $250/350

get your radiator cleaned out and viscous fan hub reoiled, this is the biggy that kills a lot of the heads when age creeps in.

This 1 is parked correctly & right way up .

Think the snorkel not only help the engine breathing but improves fuel economy ,
this one seems to run on the smell of an oily rag but its a 2.4

They are more expensive for only one reason Sorry been there done that it was a fail unless you doing it to sell.

I got a 10% improvement in mileage with fitting a snorkel.

Well I've just booked in for plugs, injectors, radiator etc etc
Thanks for the help with spending my money.:)

Just check plugs, chances are if starts good they are fine. Cheap and easy to do yourself.

Think economy gains are more seen in na vehicles as turbo will(should)suck enough air unless filter seriously blocked.
Still a good idea tho for cleaner air and risk of hydraulicing in crossings.

Water pump too while its there , and cambelt if it has one and is anywhere near due. ... having said that , my mechanic is a mate so when my land cruiser gets a birthday atleast I know im not getting tucked ..
If you find a good mechanic look after him and see he never goes thirsty ..

I have a noticeable improvement. Can't remember if I changed the filter at the same time or not?

Is your vehicle turbo?

Gimps is 1kz too if its the same one he bought last year.

Mines now up to 290,000 km's. Original radiator, engine, head, never been opened, never had a new radiator, snorkel, or big bore exhaust. Driven hard too. 1kzte manual surf. Probably been wound back upon importing too like every other truck, so could be double that. Ive now heard of 1kz's going round the clock on the original head.

If I've said it too much stop me, but its all about oil and water.

Keep on top of the servicing (which you are) and an even keener eye on the gauges. If something is slightly out of normal, find out why.

When I bought mine some a few mechanics told me the heads always go, blah blah blah. This is the lowest KM vehicle ive ever owned and I always service them the same - 5000km or if something appears sus, whichever comes sooner.

Drive it as hard as you like, but keep an eye on those gauges and services, and you will have a long and happy run :)

Chris

5000 k services say it all that's the answer !

1 kzte, 260,000k on the clock but been wound back for sure

Interesting.

Cam you'll find that a turbo only sucks a tad harder than a non turbo, with diesels not running any vacuum the difference is far less than on a petrol.

Anyone seen one of those muppets who runs the snorkel backwards?

Doesn't that grind your gears?

I always used to run mine backwards off road(don't have one on the cruiser). Can completely fill an air box with gorse or broom flowers in 20 min driving up here!
Also saved me a hydraulicd engine a couple of times.

theres a terrano floating around queenstown with the snorkel head sideways flush with the windscreen, just asking for any spary off the wipers to be funneled in.

Must have a Merlin in it awaiting water injection:cool:

Never thought of the gorse, never really had that problem :)

If you dont have a valved water trap, I can see why.

Still annoys me

I've never used the truck to bulldoze through gorse or broom, but I can see your idea has it's merits. ;)

This off the Airflow site.....
In the case of the air ram being turned away from the direction of travel the result is lessening of the positive pressure that is desirable. In the extreme, a vacuum is caused (i.e. turning the air ram backwards which may cause engine damage and should only be used over short distances).

This off the Donaldson site....
All Air Ram inlet hoods MUST be installed with the screen facing forward to ensure best performance.
Airflow restriction will not be reduced if the Air Ram faces sideways; but if it faces backwards, restriction does increase and adversely affects engine performance.

But then this off the Safari site....
By rotating the air ram to face away from the prevailing wind/direction of motion, the air ram delivers additional protection from the choking effects of snow build-up inside the air intake.

Yep spin back round when ya take ya hubs out to go back on seal.
Not much ram affect in low second anyway.:D
