Opinion's on sheep shagger hilux's

[surf lux]

Hi guys,

It's time for a upgrade and my two options are
for 25K I could get either a 05/06 shagger shape lux with around 200-250km or for the same money a older say 02 to 04 shape 1kz hilux.
Heard alot of horror storys about the 1kd d4d engines being very
costly to maintain/injectors/clutchs etc.
So if anyones got any good or bad storys relating to these two different hiluxs I'd be interested to know which one is generally regarded as being better.
Use will be about 50 thousand kms a year and about 20% of that off road.

I only know about 1kz's from owning one and having the head go. If you do a few things to the engine to stop it cooking it self then youll have a strong motor. I did the following and havnt had any issues since. Min 2.5inch exhaust from turbo, 4 core radiator, remove trans cooler (if auto) from radiator and go external, EGT (exhaust gas temp) gauge, remove egr crap. Some people chuck manual injector pumps on which gives a good boost to power. Cant comment on the newer motors.

Find some of each model and take them for a drive. I bet you'll be hooked on the later model with the 1kd common rail engine.
They have heaps more power and heaps better fuel economy than the 1kz
The main problem the later engines had was the injector seat seals would leak causing combustion gas to blow into the rocker cover putting sludge into the oil which can then block the oil pick up in the sump.
So I would look for one that has been well serviced. Possibly had new injectors with new seat seals. Then keep it serviced with correct oil. I would also add a pre filter to the Toyota fuel filter if it hasn't already
The cost of injectors and pump etc will be similar to doing a head on an earlier 1kz.

Here is a photo of blocked oil pick up. As a result you need to replace whole engine

the injectors are always playing up on the d4d even when new from factory ring up a toyota dealer and ask for the faults on them but i know the injectors do crap out alot.

On the up side 99% wont have even seen a gravel track from 02 on.. keep an eye out for the double cab "business" utes when you drive to wk.

Thanks for the info so far, that blocked oil pickup looks nasty,
I've driven both I like the power/handling/room in the shagger model,
but the reliability and off road ability's of them just don't match up to
the older version, going to be a hard choice....

little bit off topic but my uncle has a 1kd hilux and has injectors done twice. And not leaking seats just stuffed injectors.Does 30 000ks a year Another guy i know has run his one with the two stroke oil mix and has now done over 200 000ks with no issues. And he uses diesel from all sorts of containers.( guys a little bit ecentric).

Bought one new in 07 did 250000 km in two years majic on road or on your front lawn off road not that flash pulled front bummper off four times pannels very light .if you want hard core 4x4 buy a bugger shape. But what would i no i own three rangerovers

[callum007]

I rate the early ones.. Ive given my work one death. often carries 5t with the trailer. done 240k and only recently had the injectors done as I suggested to the service dept that it was getting sluggish.
They do seem to get lighter duty as they got newer. Panels seem lighter.. I hit the old one with a digger last week, small dent. lent on new one, bigger dent..

Buy the newer model.

Early ones, such as 05- aug08 are the main ones with the injector problems. The insides wear alot easier. especially if have run contaminated fuel.
All D4D engines (prado,hilux etc) from august 08, toyota coated the internals of the injector with a Diamond like coating. We call them DLC injectors. This has made a huge difference and we pretty much dont see any problems with trucks fitted with DLC injectors. Unless some one has chipped the bloody thing! This is a big no no.

So id only buy a truck that has had injectors replaced and has good service history, or if you can afford it, but an aug08 onwards model.
Its part of the service schedule to have injectors removed every 45000km service anyway, which involves new seals, o-rings, and valve clearance checked.
I know this, ive done hundreds of these jobs! I work at manukau toyota.
Kms doesnt matter so much as long as theyre serviced properly. Changing oil every 7,500km is a must. Always run clean diesel. Pre filters are a very good idea too.
Its something like 2500$ for a set of 4 DLC injectors.
Clutches arent too bad. Alot of cases ive seen are driver error.. (shit drivers)

I guess the main issues with 1kz's are heads, and sometimes glow plug tips breaking off and ####### the internals lol. Not really alot to go wrong though compared to a 1kd, and cheaper to fix.

Yea, those copper washers are shit. The silver ones are much better, we fit those at each 45km service. and every aug08 onwards truck has them from factory.

Whys that?

[mumbls]

mine blew up yesterday, cause unknown as of yet, servied up to 111000kms blew up at 114 - low compression. havent pulled engine down, will do when i have a spare mintue once fitted new engine. shit happens with any car, drive some, buy one you like! if you own a business consider leasing?

When chipping with a basic cheap ecu chip, like most of the ones seen are, it plugs into the common rail, and intercepts the signal to the ecu. It tricks the ecu into thinking the pressure in the common rail is not enough, when it is. so the ecu ramps up the pressure to above normal. the fuel system is good to a certain level of pressure. they run up to 160,000psi easy, so whats it running with a chip? probably close to 200,000. the system may only be rated to 200,000.
The system is then running outside the ecus parameters. Ive seen a lot of injectors have swollen tips, from huge pressures in the system. Some swollen so much they can hardly even be removed from the head.

Theres even one case of a broken crank. Too much pressure in the system, the injector fired on combustion and pretty much blew bits of crank out the bottom.
