    Question Please identify this pipe

    Good evening fellow Land Rover owners.

    Can someone please identify for me the pipe towards the centre of the attached picture coming out from the rear of the gearbox. The reason I ask is that it is leaking transmission oil when the engine is running.

    I presume that it takes the oil from the transmission forward to be cooled before being returned by the pipe that disappears at the top of the picture.

    In the morning I will try and tighten up the nut at the top of the pipe in the off chance that this is an easy fix.

    Thanks in advance,

    crl

    please identify

    Check on discovery2.uk site, this fellow had to replace these pipes. I had a similar situation but proved to be the pressure valve (deisel td5) at the rear of engine

    They are the pipes that take the ATF to the cooler which is at the bottom of the middle radiator pack

    Not unknown for those pipes to leak (come loose) as well as fail completely, although they normally fail at the flexi section on the swages where they join the cooler.

    They have "O" rings in them on the solid ends, maybe worth check tightening it to make sure its not simply come loose

    Thanks for the replies guys. I crawled underneath this morning and tried to tighten the nut but she was already tight.

    So once again my Disco spends a night at Land Rover awaiting assessment and repair the next day.

    Luckily I have ready access to my Mum's car, ironically a D2A. Pretty sad when you think about it, I'm 34 and I still have to ask Mum if I can borrow her car!

    The possibility here is that the Oring has actually been blown out or damaged. Undo the pipe and drop it out, and check to see if the Oring is even still there. I have seen a few come loose and the Oring imediately gets blown away with the pressure. The other possibility, the worst case, is that the thread is damaged thats why it can't be tightened further. This is serious, as in their infinite wisdom, LR (ZF) decided to remove the steel adapter fittings and screw the pipes directly into the pump housing, which is aluminium. That is a retrograde step if ever I saw one.

    Hope the first scenario is the one...

    identify this

    As i previously pointed out, when the fuel reg on the td5 goes--deisel flows down the block and over these pipes--by the time it has flowed that far it is all dirty and unless yours has a definite red tinge to it Iwould check this.

    Yes it's definitely transmission fluid.

    Now I am in the process of replacing my auto oil cooler-it startedwith weeping on the pipes(I also got caught trying to tighten those pipes) check under the radiator covers (UNDERNEATH THE CAR) mainly the left side there maybe a very slight crack in the tubular canister that the pipes connect to on the auto cooler. You will also have a build up of oil on the main radiator- if so -directions on the UK site for the removal of the intercooler gives you access to the auto cooler, DO remove the fan though, makes the job a little easier. Best of luck Greg
