Hi all, reading back in previous post about replacing injectors on the 2.8 rodeo at about 150,thou klms cause they can burn hole in top of pistons has any body else had this problem or was this a one off. Also remember reading a post not so long ago and some one was saying the injectors are worth a fortune for them is this true or no dearer than say a hilux. I thought some one said in the vicinity of $1000 to replace all four ???. Regards Steve M

Never touched mine when I had one. Did about 250,000+ and ran sweet from day one until I foolishly traded it.

Once again AJB, same same, but at 280000.
(Doesn't the man listen, or is he just being thorough?)
No offence Stephen M, but I think '666 is the only bloke with a bad bite on a 2.8 Rodeo. Sure, I bagged our 94 model for appalling, woeful, atrocious and potentially dangerous turbo lag, but apart from that, it was the Ducks Guts: sorry it's gone.
I thank you for MM regarding the 99 model that you've just test driven: seems that they fixed the lag problem in the 5 year interval. As I think I said, our 2001(plated)
3L is good as gold wrt lag, but I just don't think it is quite as good as it could be.
Stephen, I'll be the bunny, and ask for complaints re 2.8. (Then I'll duck).

Na pretty much decided on a rodeo, over the gutless hilux, yeah great off road but over being the last on the cue all the time. Trying to con the wife into some $$$ and I would buy myself an SR5 99/04 hilux but that aint gunna happen so only have $15k to play with just havnt told her how much to add all the extra's, OME, snorkel,lift, new UHF, muddies, diff lock etc. Going to tidy the old lux up over the weekend, steam clean, repaint the bullbar, clean all the dust out the air vents etc, new pin stripes (have in box when old bloke hit the rear tray just never put the rest of them on) repaint inside the rear tray and then try an flog her off. Bloke at work was gunna buy last year when I was gunna buy trucksters patrol off him but he has already bought some thing but few other blokes interested so should go pretty quickly. Will put 12 months rego on it next week so should be a good selling point as well.Unless I win lotto in the next couple of weeks which aint going to happen seen as I dont play it. Going to have a look at another rodeo tomorrow but still have to get the wife to sit in one as she is just on 6 foot and always complained of the lux being too short for her legs. Might have to modify the seat runners or some thing so the seat slides back further.Cant think of any other vehicle that suits my needs and after having 2 dogs in the back of the lux today in 41d only for 15 mins had to take to work to get vacinated thank crist they werent in the back of my wifes new car, bloody slobber from one end to the other in the ute well.Regards steve M

Why would you just replace them? if you are concerned there may be a problem why not take them to a diesel injection shop and have them tested, if they find them leaking or have a wrong spray pattern they can usually overhaul them and only fit parts required.

Hi there Chris, havnt actually purchased one yet just doing some home work before I do. From a previous post some one was saying that even with out known knowledge that the injectors can stuff the top of the pistons at a certain amount of klms even if vehicle is running ok but seems that he may have been the only person with that problem. Have heard they are expensive to replace but looks like its not an issue any way. But yes that would be my first port of call to have a diesel mechanic to check them out if I thought they were to be an issue. My motto is if running ok dont touch except normal servicing but if it was to be an issue then I would get the injectors checked but doesnt seem to be an issue. Regards Steve M

Hi Stephen et al,

Like most other replies, I can't see a set of injectors suddenly deciding to start burning piston crowns. Before the spray pattern got that bad I'd imagine there'd be other symptoms like loss of power and plenty of black smoke. And as mentioned, a injector test is pretty cheap insurance if you're worried. Go to a diesel injection pump & injector specialist, not just any mechanic.

Also, the so-called "turbo lag" of smaller capacity turbo diesels is much more likely to be due to severe underfuelling when off boost and at low boost. This was common on mechanically-injected TDs, to enable them to meet ever stricter emissions requirements. A bit of judicious 'tuning' of the boost compensator will usually bring about a remarkable improvement in low-boost, low-rpm performance, without anti-social smoking.

Again, see a reputable injection specialist (or if you're feeling brave, send me an email and I might be able to supply some info.) However, I wouldn't increase the fuelling of a turbo-diesel without fitting an EGT gauge (but then, you'd expect me to say that, wouldn't you?)

Hi guys
Re Rodeo injectors we have owned 7 2.8 tds all taken to over 200,000 ks 3 of them cracked pistons, 1 at 189000ks 1 at 205000 ks and 1 at 238000ks we rebuilt them ourselves and the comment on the injecters were that they were stuffed but pumps within or close to spec.
The pistons all showed heat spots and some showed minor to major cracking.
In all cases No 2 piston was the one that failed which causes the sump to pressurize and force oil through the pcv system and into the intake which makes the engine want to run away to destruction if you disengage the clutch.
The piston has a steel band at the top which cracks scoring the bore which has to be replaced.

When pulled down these engines showed very little wear and were well serviced and looked after.
After these problems we replaced injectors at 150000ks and had no more probems and am quite aware that others have had very high ks without problems

On the average these units are very robust and reliable.
