    A Few Issues to Sort Out on my D2 TD5 - Need a Little Help

    Hi,

    I joined a few days ago as I have just purchased a 2002 D2 TD5. I've been reading a bunch stuff on the forums and its a real privilege to be a member of such a great community. Its really cool to see everyone helping each other out so much and very knowledgeable people out there.

    I bought my Disco with 190 km from a very honest man who purchased it new of the showroom floor, he's had it serviced regularly with the paper work to prove it and has taken really good care of it as far as I can tell. I bought it interstate and caught a plane down, checked it out and drove it some 1300 km back to home to Brisbane where I put it in for a safety certificate inspection with RACQ. I know they are a bit hard on inspections but since I am buying it I prefer it that way. I have a reasonable knowledge about engines and cars in general but I have never owned a Land Rover before and I have never owned a diesel before so I need a little help as I go along.

    First up it failed a few things on the rd worthy - some where expected some not. Here's a list of what failed.

    1. Front drivers seat assembly - excessive free-play
    2. Rear number plate lights inoperative
    3. Front right indicator lens cracked
    4. Hood lining insecure
    5. Rear air bag suspension faulty
    6. Front diff leaking oil
    7. Wide spread engine oil leaks
    8. Gearbox oil leaks
    9. Transfer case oil leaks

    The only 2 things I was surprised about was the hood lining and the air bags. The hood lining is actually in really good nick, just coming away marginally in a couple of places - which I intended on fixing but didn't think it worthy of failing a rd worthy. The air bags where replaced in 2012 and the system has no leaks and seams to be working fine - goes up and down with the 4WD mode button on the dash (I had to read the manual for that ). When I questioned the inspector he said that in his opinion the air bags where too soft and did not provide satisfactory spring action when going over a bump and was adamant it was the air bag and not the shocks/dampeners.

    After researching the forum I then took it to M.R. Automotive at Redcliff to get their opinion as some of you guys rate them highly. I have to say I was pretty impressed with M.R. as they provided good free advise, took the car for a drive and spent some time talking to me about it. They considered that the motor had a bit of a miss in it and that it was running a bit rough shaking around a little. I thought this was just because it was a diesel and was expecting to hear that . I hit the oil leaks up with a high pressure cleaner the day before to get a good look at what was going on when I took it there, and they wear of the opinion that the transfer case was leaking from the main input shaft area and needed to come off (the leak is quite bad). apparently there is an on going problem with this as Land Rover have been using the same transfer case for years and are still continuing to use it and have never addressed the issue. M.R. offer to machine the casing and sleeve it to fix this problem permanently which seems logical to me. Does any one have input/advise on this? I could save a bit money by purchasing a sleeved case and doing the job myself and was wondering whats involved in doing it myself - are there any traps with shims and/or pretensions? Is there a good guide on the forums for transfer cases? I haven't had a chance to do a search so any help would be appreciated.

    M.R. were really busy and couldn't fit me in for two weeks to look at it properly - I have it booked in for a compression test next Thursday 10/11 and for the transfer case pending the result of the compression test.

    I went to Lee Bros & Co upholstery for the roof lining but they are so busy they cant fit me in to next year. That's no satisfactory and after talking to them they agreed that if I could removed the hood lining and brought it in they will find the time to re-upholster it. I had a quick look around the net and found some written instructions on a UK site and the general conses was that its not that difficult. Has any one got any information on this?

    My Disco also has twin sunroofs and I want to fix any water leaks while I am at it. From that UK site I mentioned the leak problem seems to be at the junction of the drain pipes on the corners of the sunroof tray which can be fixed easily. The sunroofs are not really leaking at all but I do see some very slight brown staining on lining which means water getting in some how maybe through the roof rack rails also. Any advise?

    I'll be pulling the rails off and spraying the roof as well because the paint is a bit faded - paints good every else. If I'm going to pull the lining out, fix the sunroof and remove the rails to seal the mounting screws then now is the time to paint it.

    Due to the fact that everyone is so busy there is now way I can get all this stuff fixed in 2 weeks for the safety certificate from RACQ so I'll have to get another - I plan to use M.R. since they doing some work on it.

    Now that I have a couple of weeks I decided to address these issues and check the mechanics out as best I can but its all really hinging on the compression test next week. So I jacked it up and set to work.

    I removed the front drive shaft and replaced the universals with extra heavy duty with grease nipples from M.R. Automotive. First time doing a cardinal joint - that was fun ! I then took it to Hardy Spicer and had it balanced for good measure.

    driveshaft1.jpg

    Next I replaced the front diff pinion seal which should fixed the leak.

    On advise from a very reputable LR mechanic (whom I won't identify just in case I cop some flack over this) explaining that there is a cavity between the back of the sump and the transmission plate that fills with oil and crap over the years and gives the result of dripping oil where the sump and the bell housing meet - I drilled a hole into this cavity to let the oil out. However his explanation of exactly where the cavity is located was incorrect - advising that the casting line on the bottom of the sump was where the cavity wall was. There was a lot of oil in there alright about 5 ltrs of it LMAO Oh dear! Well I didn't mind to much because the sump gasket really needed replacing anyway and it really was a blessing in disguise because that then made me do more research and I learned of the infamous oil pump bolt which I consequently replaced and all though the bolt was tight there was NO locking compound on it!

    For those interested here is a pic showing the wrong place to drill

    sump1.jpg

    And here is a photo of where it should be - after I had the sump welded.

    sump2.jpg

    sump3.jpg

    I replaced the number plate lamps. I purchased a new front right hand indicator assy genuine from Land Rover for $55 which was surprisingly cheaper than Ebay.

    I ordered genuine engine mounts of Ebay for $175 each from 4x4 Industries along with sump gasket, centrifuge oil pump drain pipe to sump gasket, oil pump bolt and inlet manifold gasket.

    I then pulled the EGR valve and inlet manifold off (which was loose in my opinion) to inspect the sludge and was very happy to find the EGR valve inlet blocked and not much sludge in the manifold.

    EGR.jpg

    I cleaned out the manifold with degreaser but left the EGR for moment because I need to pass safety certificate inspection and it can stay blocked. I will delete this later.

    From info I found in the forums about filters I contacted Mann & Hummel and the gave me the contact of Active Air Spares in Sumner Park who are there main stockest in Brisbane. I had a chat with them, they are a small business but keen to help and competitively priced. So if anyone is interested I bought

    ZR700X Centrifuge Rotor $38
    W7139 Oil Filter spin on $16
    WK7302X Fuel Filter $41
    C25146 Air Filter $22
    Provent200 $173

    They had the provent 200 on the shelf but the other stuff they got up from Mann & Hummel in a couple of days. They are a small business and are keen to keep stock if the demand is there.

    I have to thank you people in this community for the Provent - I only learned of this by reading the posts.


    Looks like I can only insert 5 photos so I need to do another post - hope I am not boring you guys!

    1. Front drivers seat assembly - excessive free-play
    Not sure what you can do about that, you'll probably need to take the seat out and see what can be done, maybe a bit of bending or welding a bit of material back on.

    2. Rear number plate lights inoperative
    3. Front right indicator lens cracked

    4. Hood lining insecure
    That's actually a roadworthy thing? Did you annoy the guy.. Even the UK didn't have that kind of thing, thankfully SA doesn't have it all

    5. Rear air bag suspension faulty
    There isn't any adjustment for the rear air bag pressure, you can change the rest height with a nanocom. However, it is more likely that it's rebound and damping so new shock absorber not bag.

    6. Front diff leaking oil
    7. Wide spread engine oil leaks
    Check the Fuel Pressure Regulator, this can easily be mistaken as oil, it is diesel after all and collects all the dirt on the way down. It then collects in that cavity you were aiming for
    The FPR is well known for leaks

    8. Gearbox oil leaks
    It looks like an auto, so as you'll see, check the pipes running to the cooler. Specifically the swages from rigid to flex and the actual connectors to the cooler. Don't be gentle, if they come apart or the swages can be twisted then they will fail. As a temporary (like forever temporary maybe.. ) you can replace both swage and connector with hose clamps, suggested best method is two clamps, one on either side of the raised section of the pipe.
    Leaks elsewhere, like ATF from the bellhousing, would require box out to fix seals.

    9. Transfer case oil leaks
    There are a few places this can leak.
    GEARBOX output shaft seal, you might no be able to tell the difference after it sneaks through between EP90 and ATF
    Transferbox input shaft seal.
    The O ring on the intermediate shaft, this is the sleeving job. You may get some mileage out of just O ring replacement, that was what I just did.
    The front casing to main case face, I reckon I have seep from here, I should have done that when I had it off.
    The front casing side plate - I did reseal that one.
    The rear output case.
    Lots of the bolts go straight into the transfer case cavity so need some thread lock or thread sealant/tape to avoid a seep.

    It's a creeping job though, if you take it off to do the intermediate, I suspect you'd be so far into it that you'd want to think about doing a full transfer box overall (including front diff) otherwise you'll get it back together later and think why didn't I (or maybe it's just me). They are apparently not too complex to do, but I've never done one, yet.


    "Now that I have a couple of weeks I decided to address these issues and check the mechanics out as best I can but its all really hinging on the compression test next week. So I jacked it up and set to work."
    The other check is the injector loom, pull off the connector on the ECU next to the battery and see if any sign of oil and pull off the connector drivers side front underside of the rocker cover (you'll see the connector). If either of these show oil then it's time to replace the injector loom (under the rocker cover) and give the connector from engine to ecu a good clean.

    Looking around I noticed a few things.

    Is this a temp gauge in the fuel regulator and whats it for?

    Fuel regulator.jpg

    And I notice this switch on a vacuum for the turbo - what is this and what does it do? I think one can adjust boost with the adjuster on the turbo but this is my first turbo so I am learning - any info on this in the rave or workshop manual etc?

    turbo switch.jpg



    I am worried about the engine running roughly so I am trying to check everything I can. I pulled the inter cooler out thinking there might be oil in it if too much blow by but it was clean! washed it out anyway - the provent will fix that.

    The wiring harness (internal and external) has been replaced in 2010 identified during servicing. I checked the external and its all clean red socket on ECU is good. I do notice oil just starting on the plug to the rocker cover is this a sign that the internal loom is contaminated?

    loom.jpg

    I guess it is possible that an injector is faulty but if that was the case I would expect it would being alot worse than what it is. Have to keep my fingers crossed for the compression test.

    I'm in the middle of putting it back together now - all and all its looking pretty good.


    Later on after all this I would like to fit a boost guage and EGT sensors any info how and where to fit these?

    The previous owner tells me He purchased the factory chip up grade as soon as it came out. I'm assuming this would have been a complete ECU swap - the code on the ECU is NNN500030. Like I said I will be looking at deleting the EGR and maybe the CAT - not sure if I need a bigger intercooler. Can anyone point me in the right direction for info on getting it remapped in Brisbane? Also would like info on the best type of OBDII scan tool for these cars, can you get one for your laptop? can I flash the ECU myself? how much do they cost? etc?

    I'll keep posting as it progresses - Thanks for your help.

    It's a temperature sensor on the fuel pressure regulator, the ECU does 'stuff' with the knowledge, not sure what...
    The solenoid on the turbo is under ECU control, it monitors the pressure via the MAP (found on the inlet manifold) and when it reaches the right amount of boost it operates the solenoid causing the wastegate to open. As I understand it, this means the wastegate is either closed or fully open (give or take) on the D2 and not graduated opening like the 300Tdi and TD5 in the defender.
    I can't tell from your picture if there is any oil on the actual pins, you might be better using a mirror to look at the engine side. Replaced 5 years ago might not rule it out, but I personally haven't had to deal with this yet.
    The killer on these engines is that to do the compression test you can test 1-4 via the glow plugs, but no 5 has to be via replacing the injector with the tester (under the rocker to boot), presumably a special TD5 item.

    If you are removing the EGR, then the blanking plate, if placed on the end of the exhaust manifold, not EGR cooler, is a reasonable place. People oom and ahh about would somewhere else be better, but in the scheme of things, it's an easy fit for a bit of info, versus removing the manifold, drilling, tapping etc.

    I think the 2002, if pre-facelift and not the EU3 (which has like an exhaust silencer like EGR cooler on the front), can be a cheap upgrade to the D2a intercooler. I'm not sure how the D2a intercooler stacks up against an aftermarket one though, I'd be interested to know if the difference is worth it for mine.

    OBD tool wise, there are 2 or 3 that you should consider. A britpart type item, which I can't remember the name of and nanocom. I've not used the two back to back, so can't comment with any authority on what is best.
    Nanocom is a nice device though, easy to use, has a few niggles (the autobox screen needs sorting out as the fields are too short and values are 'odd' for temperature) but everything I've tried has worked. Also, no need for a laptop or anything, mine lives in the drivers seat base cubby box.
    Nanocom supports both read and write of the engine map.

    I'm about to get a bit of exhaust work, removing the cat and middle silencer, all reports are that it's a noticeable improvement.

    EDIT:
    Another source of oil leaks, front and rear, is a plastic blanking plug on the camshaft, not easy to check the rear one, front one is pretty easy.
    I notice on the FPR picture that your lifting eye is still bent at 90 degrees. There was a TSB that it should be bent at about 130 so as to avoid chafing the heater matrix hoses. I made up one of these (mine was missing), fitted it and was happy as. Replaced the engine mounts and the matrix hose was fouled and worrying, that was how I stumbled upon the TSB, so I'd advise to take it off and just 'unbend' it to make sure it's got a heap of clearance. Also, you have great access to the FPR with the manifold off, so if it shows any signs of leaking, would be a good time to replace it.

    WOW fast response Steve thanks.

    I forgot to mention the front drivers seat is electric and yeah not sure about that either.

    I think I've got the oil leaks sorted now except for the transfer case. I'll be sure to check the back camshaft seal too.

    I agree if the transfer case comes off I might as well rebuild it - be crazy not to.

    I think mine is September 2002 and is pre-facelift but I think its EU3 because its got the butterfly in the EGR and the EGR cooler on the front of the head. Is there any difference in ECU map for EU3 as opposed to EU2 and below? I was under the impression you could delete without changing software - not sure with EU3 though?

    Great pickup on the lifting eye Steve - which way? you say unbend it towards the front of the car so it has 130 degrees i.e away from the firewall?

    Which ones are matrix hoses?

    Forgot to mention M.R. are doing the compression test via injector ports - for the exact reason you mention.

    Wheres a good spot for the boost sensor - on the NO-EGR pipe (yet to be fitted) between the inlet manifold and the hose?

    Hi, some extra info for you, that FT(fuel temp) sensor in the FPR is used by the ECM's addaptive strategy for hot start and acceleration fueling calculations, quite important to give good readings but it can be checked only by reading live data inputs with tester

    the wastegate modulator as said is restricting the pressure to the wastegate valve as to keep the boost as high as possible all the time, it's closed at low revs and opens gradually as the load increases

    as your own tester if you go for a nanocom you'll be able to remap that NNN ECU yourself and if you are determined to buy one wait untill it arrives then you can read fault codes and fuelling inputs to see the cause of the rough running dont torment yourself to go on a guessing basis

    you can insert the T piece of a boost gauge in the hose which comes from the intercooler to the bottom of the wastegate modulator

    Good luck

    Thanks Sierrafery. M.R. have checked the fault codes and it doesn't really have any. Apart from a some S+M errors - hope that dosen't cost me a selector switch dang their expensive.

    Where can I find Technical Service Bulletins such as the one Steve mentions?

    There are TSB's in RAVE, you can find some online for free if you search enough or there are sites where you can find all of them against a certain fee ...if no faults are logged in the engine ECU it means the rough running problem is most probably fuel supply related cos the fuel delivery system is not covered by diagnostics though it can be a bad sensor which's readings are inside accepted limits to not trigger a fault code but not good enough for the engine management to work perfect and that's traceable only with live data readings

    For what it's worth, a number of us have our Nanocoms set up in the car in instrument mode. Mine uses the BBS carrier and is attached just in front of the L/H gearbox lever. Gives you accurate instantaneous volts, coolant temp, turbo boost, speed and revs from memory. Then you just add whatever else you want in the way of gauges. Strongly recommend EGT, transmission temp and engine oil pressure. If space becomes an issue - add a Mudpod console.
    You can also get a low coolant alarm from our e-shop which is very cheap insurance.
    Without rechecking posts, I'm assuming you already have the RAVE CD - again available from the shop.
    Welcome and enjoy!

    Rear number plate lights failure is usually due to the rear door handle gasket failing and letting water into drip and corrode the the number plate fittings. Starting to become a common repair as the D2s age.
