    Hi everyone, first poster here and hope to contribute more.

    I need advice please. I noticed a loss in power recently on a motorway drive home along with a strange "whirring" sound coming from the bulkhead behind the centre console under acceleration.

    Local garage has test driven it and had it on the ramp. Its been diagnosed with a leak in the cross pipe that links the turbo to the EGR. It will need replacing and by all accounts its a very difficult part to get to. 2 ways. One to remove the gearbox and the other to lift the body off the chassis. Both extremely expensive with the part also costing an arm and a leg.

    Its a 2007 disco 3( 118K miles) and I'm having to consider the cost implications versus scrapping the car for parts.

    Is there any way to get to this pipe without the costly measures stated above? Apart from this problem the Disco is great and ran brilliantly so I don't want to have to scrap it.

    What would I expect to get for it without the work done ?

    All advice very much appreciated.

    I think you dind its called a crossover pipe and is what links the right hand engine back to the turbocharger and has nowt to do with the egrs.
    They tend to fail due to lack of support after any big gearbox repairs.
    There was a thread on the D3/4 forum where a guy did one in situ, but apparently it was a pig of a job!
    I will go and find a pic

    after reading that thread i see it can be done without removing the body and gearbox, learn something every day as i always thought that was the only way

    wasn’t there also someone on the D3 forum who had second hand cross over pipes , re welded them and then sold them

    those prices are indeed eye watering and imagine the guy who done the work saved a serious amount of cash

    there was another one i saw who hired a small crane and lifted the body off on his driveway , then done all the hard jobs whilst the body was removed , think it was the aussie forum???

    Any sensible mechanic would run very very fast and then ring in sick!

    What was wrong with the oil return pipe?
    I dont think I have ever changed one on a truck ever, gaskets and turbos yes but not the pipes.

    Both the feed and return pipes were badly corroded, they look like a bit of gnarly tree branch - the return pipe is still on the truck at the moment, but here's the feed:-

    It is, yes. I suspect it's been a horsebox for a large chunk of its life, given the state of the engine. The design of the box means its not a tilt cab anymore, and to get to the engine you have to take the seats out, take the carpet out and then remove about 20 screws to take off the rather crudely cut engine cover. It doesn't encourage preventative maintenance, that's for sure!
    It also doesn't help that horse owners will spend any amount of money on a horse and its welfare, but when it comes to the transport - Nah, just bodge it up for the plating!
    So while I'm there it's getting a new turbo & oil pipes, compressor cooling pipes, fan belt and alternator. Oh, and a new throttle cable!

    I thought so as most truck engines have a slight misting of oil around round the oil pipes to turbo gaskets and yours is bone dry and rotten.

    Last time I saw a truck with a mechanical throttle must have been around 1993/4:D

    You're getting good at this! It's a 1994 MAN L2000 8.153, and a bit of a challenge to get bits for if you don't want to bend over at the dealers parts counter - thank gawd for the internet. And yes, oil-wise, it's 'as dry as a buzzard crutch' on that side of the block. The exhaust end of the old turbo is so corroded it looks like it came of a shipwreck.
