    Not there I`m afraid - It`s round the back somewhere underneath, up by where it goes into the timing case

    most likely that will be one of the pivot bushes or the top cover seal leaking near the top and running down the face.

    I don't think there is any possible way of choosing your diesel fuel anymore.

    AFAIK once the Brisbane refinery stops production (which only supplies around a 100km proximity to Brisbane) , all diesel fuel in Australia will arrive by ship from Singapore.

    It is one brand.

    I spoke recently to tanker driver and funny as it sounds , the further the diesel is trucked , the cleaner it gets.

    The driver was telling me that after a long haul, a large quantity of sludge settles out into the tanker's sump , which unuseable for anything but road fill or bunker if centrifuged.

    So, it's all the same now , except Brisbane metropolitan , foams like hell and ****s the seals in old pumps.

    Yes, 2 stroke (not synthetic though) does help.

    Some do it 200:1 which I think is excessive.....more like 500:1 is my thinking.

    Possibly in a td5 with its hi temp hi volume recirculating system @ 200:1 you could be ok.

    But like the guy said, it might lube your pump but doesn't stop seal contamination.

    Thanks for your help guys - I`ve now ordered a seal kit off Ebay for `bugger-all`- BOSCH diesel fuel pump repair kit Land Rover Defender 2.5TDi Discovery 2.5TD | eBay - I`ll let you know how I get on with the rebuild when it comes - Thanks again all

    BTW An extra BIG thanks to Blknight for these links too

    As an extensive user of Bio-diesel I can confirm no problems with fuel seals in either my previous D2 which I ran on Bio for about 5 yrs nor on my present D3 2.7 which I've done for over a year now. Also my mate 3-Gees who brews the Bio ran a D1 Tdi 300 for about 5 yrs and and has been running a D2 TD5 for approx. the last 5 yrs on Bio without seal problems. Bio actually acts as a lubricant in diesel, even at percentages as low as 5 or 10% IIRC. Freedom used to sell a B-20 blend here in Brisbane which I've also used but I think it was more economic to move the plant overseas due to taxes, excise, etc.

    I had my 200 and 300 pumps and injectors rebuilt by DieselBob Tuning. He is pretty good and knows what he is talking about. I had the 200 set up to run vegoil as well as diesel - he uses heavier duty parts and special seals for that, as vegoil also attacks the standard rubber parts.

    I can't say about the rest of the EU, but the UK has a lot of diesel vehicles and almost all fuel stations have two grades of diesel, just like petrol. The higher grade is marketed for higher performance, but does give better mpg, runs smoother and has lubricants and cleaning agents in it which make it quite apparent to the interested driver which type they're running on. There is a noticeable difference in the characteristics between different suppliers, too. I found the BP premium diesel by far the best, Texaco the worst (noticeably worse than supermarket stations like Tesco and Asda).

    FFS this thread is piles of the proverbial, sprinkled with misinformation.

    Australian diesel is equivalent to the best standards worldwide. Including lubricity.

    I was just at an international conference where the same was confirmed.

    Modern fuels are actually better quality than the old high sulphur fuels (including lubricity), however the aromatic content has changed, which makes life tougher for old seals which have already gone hard.

    Modern commonrail diesels actually are much more sensitive to lubricity than older diesels.

    At the end of the day seals wear out and need to be replaced.

    All diesel in AU must conform to the same spec. There are only 3(?) refineries supplying most of the retail diesel in AU these days.

    I had a very good run with biodiesel in my td5, but now I own a commonrail vehicle I am trying to find answers.

    I have been on the ARfuels and the Australian Biodiesel websites this morning just trying to get a positive response.

    the ARfuels site waxes lyrical about several large truck fleets running their product and that they sell to Shell for mixing , but none are actually game to say their product is ok for any particular brand of common rail diesel engine.

    They say emphatically that it burns better , cleaner , increases lubricity so it should not damage any mechanical item it contacts.....that in fact is a superior product to dinodiesel......then why doesn't our country, our government , and the motor vehicle manufacturers who endorse the new low sulphur blends , give endorsement to what is touted as a superior product all round to the benefit of every diesel engined vehicle and to the environment.

    Am I missing something here?

    Are the biodiesel producers not handing enough kickback to the govt to get the endorsement it needs?

    Are the motor vehicle manufacturers around the world in collaboration with the major dinodiesel producers?

    As mentioned earlier there is some serious bull**** going down here.

    The reason is pressure... under the severe pressures of a Common Rail the Bio changes behaviour- and can do real damage to injectors and pumps..

    And Bio fuel on mass has less calorific energy, so consumes significantly more for the same distance.

    And a little touted issue - BioDiesel generates MORE emissions than Dino Diesel BIO-Fuel stuffing things up

    yeah Tombie , I have read and understood what you and many others say and it was because of another report where $12,000 damage was done as a claimed result of using a biofuel in a common rail diesel that I did a bit of research this morning.

    The two organisations I mentioned above refute this and make the claims that I have mentioned , hence my comment about bull**** flying around.

    ARfuels claim they have had trucks with common rail systems total more than a million km of trouble free driving.

    I think when companies such as these make claims like they have , that they should back it up with hard evidence.

    Maybe I should let them sponsor and warrant my vehicle , I'll even let them sign write it.
