pugwash Posted February 15, 2008 Share Posted February 15, 2008 Now that i'm running a diseasel powered vehicle i need some general advice. How long do diseasel injectors realistically last. The landcruiser is a little underpowereed and not very ecenomical and it has been suggested that along with a good service it might be worth getting the injectors refurbed. The car has done 130,000 miles, is 14 years old and i don't believe the injectors have been serviced although i know the pump has been. I don't know how big a job it is to do on a Landcruiser- although looking at the manual it seems to be a case of undoing the injector pipes and unscrewing the injectors- so not very long then! I have to take the vehicle off the road to get the PAS pump refurbed so i might as well do this at the same time. Does anyone know of a diesel injector specialist in the southwest that does really good work? On a different note it would seem that the fuel pump seems to work on the same principles as a 300tdi- ie just turn the screw to dump more fuel in. At this point am in the world of EGT probes to ensure i don't go around overfuelling the engine? The engine as standard isn't intercooled, so is it worth waiting until i can get an intercooler fitted? What exactly is the fucntion of this "screw", am i right in thinking that i just adjust maximum demand? so i only get overfueling when i have the throttle buried, or does it supply more fuel all the time? For a 1993 vehicle what emissions do i have to pass and how would fiddling with the fuelling effect this. I currently don't get any real smoke from the exhaust pipe when i floor it- this suggests to me that the engine, if anything, is underfuelled. I have also found a hole in the exhaust downpipe not far from the turbo- i have covered it with exhaust wrap but was interested to know if this would have a detrimental effect on performance or positive?

GBMUD Posted February 15, 2008 Share Posted February 15, 2008 Ah, sorry Jim. I thought you were asking about a Toyota diesel, I did not realise it had been replaced with a Landrover one. My mistake it seems. Chris Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted February 15, 2008 Share Posted February 15, 2008 These people may be able to help, they seem to have some experience with your type of vehicle. This site is more general but may help. HTH Mo Quote Link to comment Share on other sites More sharing options...
pugwash Posted February 15, 2008 Author Share Posted February 15, 2008 is this going to be the official forum attitude from now on? if someone asks a perfectly reasonable, relevant question then we don't bother answering unless it directl involves land rovers? what a shame especially as the LC-80 uses a japanese Bosch pump just like other land rover products. the ih8mud forum is yank based and has no diesel info on it, and ttlocuk forum doesn't have particulaly knowledgeable peeps on it. i'm saddened by the first 2 responses on here.

Matt Neale Posted February 15, 2008 Share Posted February 15, 2008 Jim. Did you get anywhere with the injector servicing? I used to have a contact in Bristol, but as he's now retired I too am looking for a decent diesel specialist who won't charge the earth....

TheRecklessEngineer Posted February 15, 2008 Share Posted February 15, 2008 The general consensus from other diesel forums is that injectors should be replaced every 60k miles or so. I believe that the Land Cruiser uses a Jap copy of a Bosch pump - should be nearly identical and therefore just as tuneable It may be that the engine is more sensitive to tuning so I'd fit an EGT gauge to be on the safe side...

GBMUD Posted February 15, 2008 Share Posted February 15, 2008 Sorry if you did not like my answer Jim. In the absence of knowing the answers you wanted I did the best I could and gave a pointer to somewhere I believed may be better able to answer some of your questions. If you don't like that then ignore it - indeed, you know where the 'ignore user' button is, don't you. Take notice that this is my attitude and not that of the forum. You will see that there are no smileys this time. Chris Quote Link to comment Share on other sites More sharing options...
freeagent Posted February 15, 2008 Share Posted February 15, 2008 Jim, I would say the injectors should be serviced/ replced every 60-70k do you know if they are two stage injectors? if so i have heard that the 'second stage' is quite difficult to calibrate when the injectors are reconditioned.. might be worth asking the question.. I too think the first two replies were a bit sad, I know this is a landrover forum, but as several of the forum members also run Landcruisers (at least 3 that I can think of) i don't see the harm in the odd 'cruiser' question... at the end of the day its only vehicle tech isn't it? good luck with it, I think my next vehicle purchase (if I don't blag a company car next year) will be a mid 90's 'cruiser... better make sure my coat and hat are next to yours on the peg next to the door eh...

jimmy_neutron Posted February 15, 2008 Share Posted February 15, 2008 Your talking about adjusting the pump at the same time as talking about servicing the injectors. At 130,000 miles if its had a reasonably calm life, them the fuel injectors may never of been touched and may never of been a problem. My opinion, which is not shared by all, is to only recon known good injectors once. If at all unsure, and probably in your case replace them all with new ones. Make sure they are new and not from fleabay, polished on the outside jobs. Once the injectors are replaced, see if ya really need to give it more go. If ya don't need it then don't do it.

muddy Posted February 15, 2008 Share Posted February 15, 2008 I know its not ideal but i would get the engine warm and fill a freash fuel filter with redex or similer before taking it out for a damn good thrashing. Our 130 (300) has done 130 thou i did the above and then gave to injectors to a mate of mine who does diesel injection, they were all very good certainly within limits and all cracked off within 2bar of each other i think. just my thoughts. Will. Quote Link to comment Share on other sites More sharing options...

Les Henson Posted February 16, 2008 Share Posted February 16, 2008 Getting the injectors checked is relatively cheap (about £20) as long as you remove them yourself. Adjusting them will cost more - especially if they need to be taken apart, cleaned, etc. At 130k miles the engine might be generally worn, which might be affecting fuel consumption. Look in the inlet side of the turbo for oil contamination. I wouldn't adjust anything until I knew the injectors and other basic stuff is working ok - you might make things worse. Les.

jimfoo Posted February 16, 2008 Share Posted February 16, 2008 Injectors with a very bad spray pattern can cause engine damage, and any kind of poor pattern will cause some loss of power. As far as the fuel, you should get an EGT gauge if increasing the fuel, especially on an NA engine. Put the probe as close to the engine as possible, like right where all the runners meet. You will get increased power by increasing fuel, but will also get increased smoke and higher EGT's. To counter this, increasing boost will lower both smoke and EGT's. While not Rover related, this thread explains things very well along with this one. Now that i'm running a diseasel powered vehicle i need some general advice.
