Peaklander Posted October 20, 2015 Share Posted October 20, 2015 Hi all, I've started to think about my 300TDi engine and what might need doing after ~110K miles. One item on the list, is to have a look at the injectors. I approached a local diesel overhaul specialist (great testimonials on the www, mainly for pump overhauls) and was advised that testing is £5 each and reconditioning £70 (probably plus VAT). As a cross check (and not having a clue about costs in this area) I looked at the price of new and saw quickly that Bosch injectors are £68+ VAT each. So is this a case that sometimes it's no more expensive to buy new? Or is it that new are nowadays not of the same quality as a set that have probably been on the engine for 19 years? I'm a bit confused and need some direction! Thanks Quote Link to comment Share on other sites More sharing options...
Maverik Posted October 20, 2015 Share Posted October 20, 2015 No brainer. £68 for an injector sounds a little low to me, but I'm used to dealing with 200tdi injectors which are about £168 new!!!! If you can gen Genuine Bosch injectors for cheaper than an overhauled set then go for them... 1 Quote Link to comment Share on other sites More sharing options...
Peaklander Posted October 20, 2015 Author Share Posted October 20, 2015 That's what I'm thinking but I was sure there's a catch. That's the price on Paddock's website and others are thereabouts. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted October 20, 2015 Share Posted October 20, 2015 £68 seems very low, check around and see what the average price is. Quote Link to comment Share on other sites More sharing options...
KenM Posted October 20, 2015 Share Posted October 20, 2015 I bought 4 from Paddocks about 5 years ago cant remember the exact price but was under £60 each, turned up in Landrover boxes. They were new not service exchange. Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted October 20, 2015 Share Posted October 20, 2015 If you are that worried have them tested. But at 110k they should be fine,I've seen plenty go well over 200k without any trouble.Its the common rail injectors that are more likely to give problems....

Les Henson Posted October 20, 2015 Share Posted October 20, 2015 The price to recon is rather excessive, as they don't know if they are faulty and what needs doing to correct them. TDi injectors are totally mechanical, so wear/parts will be minimal and therefore unpredictable. If they are worn/weak, then usually adjustment is sufficient to correct them. I've never yet had to have injector parts replaced. The company I use here in Swindon test them while you are there and not only advise you of their condition, but also the total price to get them within spec. I've even just been asked to put a couple of quid in the 'coffee tin' as payment Les. Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted October 20, 2015 Share Posted October 20, 2015 Hi, don't know who you tried but had mine done at Potteries diesel came back like new, so you could try them there based in Hanley in Stoke. Can't give you a rough price as I had them done through a friend. Ian Quote Link to comment Share on other sites More sharing options...
Peaklander Posted October 20, 2015 Author Share Posted October 20, 2015 Well there's a lot of food for thought there - thanks. I've really no idea what condition to expect mine to be in, so I suppose the starting point is a £5 test (well £20 really). The new prices of Bosch start at £68 and there are one or two others close to that at £75 and £84 (+VAT) I was surprised at the recon price quoted but at least I can make an informed decision once I know if any of them need resetting etc. All I need to do now is get them out. I've seen and read much advice so will be prepared to make a slide hammer if I need to. Won't be for a least a few days though - work and other checks to do first.

Peaklander Posted October 22, 2015 Author Share Posted October 22, 2015 Hi, several things have cropped up: 1) am I looking at the correct injector? 2) is a new nozzle all that's required? 3) My local diesel specialist said "no thanks". 1) I noticed that the Paddock website has changed search method (for the better) and when I looked again at the cost of 300TDi injectors I was first offered ERR3348 at £159 ea Incl VAT. I had previously seen ERR3339 at £82. Both say 300TDi So I'm slightly confused. ERR3339 is what my parts book says. Is that the one? 2) Les (above) said "TDi injectors are totally mechanical, so wear/parts will be minimal and therefore unpredictable. If they are worn/weak, then usually adjustment is sufficient to correct them. I've never yet had to have injector parts replaced." So is it just the nozzles maybe that need replacing? What is the refurb method? 3) I asked the local company if they had maybe quoted for modern injectors and not the mechanical ones in a 300TDi and again I quoted the price for ERR3339 which is lower than their refurb price and the reply was that they couldn't purchase the nozzles at that price. Well again, the nozzles seem to be <£20. So I'm getting more confused, not less. I think I should take them out, get them tested and if there's any issues that a few more quid can't pay for, I should buy a new set of ERR3339 and they should go in without any set-up. Is that the correct way of thinking? Thanks Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted October 22, 2015 Share Posted October 22, 2015 I think you are over thinking this and maybe worrying about a problem that's not there.The 200Tdi that is going into my SII has covered 232,000m - runs a treat,has even suffered a fill of petrol in the past. So unless you have poor starting,smoke or running issues I'd leave them alone.On a 300TDI its more important to keep the cooling system in order,P gasket,water pump and radiator need to be in good nick...

ejparrott Posted October 22, 2015 Share Posted October 22, 2015 Have a Google with regards changing the nozzles yourself, I know there's a good write-up about doing a 200 Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted October 22, 2015 Share Posted October 22, 2015 Iirc a 200 injector according to land rover is good for 75000 miles where as the 300s are good for 150000 miles, after this the needle on the 2nd stage wears into a dome as apposed to a sharp point, reducing the nozzles ability to inject the fuel properly.

Retroanaconda Posted October 22, 2015 Share Posted October 22, 2015 Is there a source for that? Mine are on nearly 240,000 so a little overdue a change/refurbishment by that measure Quote Link to comment Share on other sites More sharing options...

Yup,and all this from the company that states that TDI heads can't be refaced,perish the thought that anyone would consider skimming a TD5 head.(Just had one done) What LR recommends and what the real world does are two very different things.

I don't want to over think it, that's for sure. It's just that I'm at a point where things aren't running as well as they might be. There's some lack of power when pulling (no load carried). I need to read around the engine related stuff to be in a better position to know what to do. (turbo hoses, manifold gaskets, turbo bearings, intercooler clean out, lift pump check, injectors...) When I got round to thinking about injectors, I just thought I'd see what the reburb advice might be without knowing if they even need pulling to be able test them. Maybe I should leave them alone. It was the price comparison that got me thinking about what a refurb consists of and that prompted the post. I'm grateful for the replies. Yes I always watch the coolant and in 10 months and 7,000 miles this year, I haven't added a drop . I hadn't planned to do any preventive maintenance on the P gasket but I assume that the minute the coolant level drops then I would start crawling all over the cooling system. As far as ERR3339 prices go I'll just assume it's competitive pricing for new verses slightly high refurb prices at the company I picked in Sheffield.

muddychris300tdi Posted January 29, 2016 Share Posted January 29, 2016 OK, bringing this thread back up. I've just had my head off to do gasket and get it skimmed. Two of the injectors came out nicely. I got half of the third one out and couldn't budge the 4th. So left it with diesel specialist to get the stuck two out and skim. Those two injectors are now scrap. I also gave them the two injectors I got out to test, the engine has done 178000miles and drove well so didn't think there would be a problem. Apparently those two are no good either and they wouldn't be able to just re-tip them. So now need to get myself four injectors, more expensive happy days.

Peaklander Posted January 30, 2016 Author Share Posted January 30, 2016 Hi Muddy That's a bit unfortunate but interesting that they've said the injectors are spent. What made you take the head off in the first place? Quote Link to comment Share on other sites More sharing options...
muddychris300tdi Posted January 30, 2016 Share Posted January 30, 2016 It was using water and blowing white smoke, so suspect head gasket. On removal cyclender two was clean but there isn't any signs of a brake in the gasket. So I'm still a bit concerned. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted January 30, 2016 Share Posted January 30, 2016 I'm very very surprised they say nothing can be done with the injectors. It's not like there's much in them that can render them irreparable. Quote Link to comment Share on other sites More sharing options...
muddychris300tdi Posted January 30, 2016 Share Posted January 30, 2016 Well I went to paddocks and brought some new ones. It will be good to see if there is any difference in performance. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted January 30, 2016 Share Posted January 30, 2016 You can rebuild injectors yourself. The nozzles can be bought from evilbay for both TDi's. Quote Link to comment Share on other sites More sharing options...
Peaklander Posted April 28, 2016 Author Share Posted April 28, 2016 Thought I'd close this thread by saying that I finally took the injectors to Sheaf Diesel Services in Sheffield where they cleaned them (ultrasonics) and tested them. All four are perfect. They were returned same day with new washers and a set of eight washers for the banjos. Total cost £12 incl. VAT To refurb them they would have charged £70 incl. VAT each My mileage is shown as 145K. The engine was changed at 36K. Don't know if the injectors were replaced then but I would very much doubt it. So they have done max 145K miles. The engine has been serviced regularly. Removing them was very easy - the engine was at operating temperature - they were easily turned in the holes. I had a 14mm nut with the wrong thread which went toto the tops just enough to hold and then needed a little bit of a pull upwards to un-seat them - not very much. The bad running problem that I was trying to solve was actually the elbow hose from the turbo to the metal pipe going to the intercooler. It had been ballooning and finally split - thus it became an easy diagnosis for a novice like me! I hope this helps someone else. 1 Quote Link to comment Share on other sites More sharing options...
