    Haha gosh maybe I'm too used to driving more refined newer diesel engines at work all day (hiluxes and bt50s etc) but I swear that flappy noise wasn't there before...My dad actually rolled his eyes at me too and just told me to shut up and that it was hardly anything "it's just an older car" he said...Perhaps I'll focus on the actual issues like this new oil leak I just found woohoo it's a good one though, a proper leak, might put that in a fresh thread...

    With all the rain we ended up with, we forgot to go for a drive in mine.
    I pointed out all that sound insulation I had fitted, and I reckon yours felt both smoother and quieter than mine too.

    Plus the expectation that with those muddies, I was expecting at least some roughness and howling from underneath too.

    You should take a 90's hilux diesel for a spin one day just for a laugh .. to understand why the Disco was regarded so highly in it's time.

    As I remember the diesel rattle noise it makes is due to the direct injection design of the times, so while it may seem rough, back then that was considered avant garde in it's day.

    My dad's 62 series cruiser diesel was much rougher from the get go(second hand, but far fewer klms than our D1s currently have).
    Half the go that our Tdi's currently have(granted not a turbo, but still a 4.2 lit lump of boat anchor.
    He had new injectors fitted which helped with it's smoke issue, but did nothing for power. I never drove it far enough to determine it's economy for the way I drive .. dad's a Uranium footed driver .. lead far too light and gold too expensive .. but Uranium is about heavy enough for his right boot
    He used to get between 6.5 and 7 km/lt!
    The only thing it had over the Disco's direct injection was that it's indirect diesel rattle(the typical clack clack diesel sound you hear from a diesel) was much quieter.
    So at about 1500 - 2K RPM all you really hear was a droney exhaust sound, rather than the Tdi diesel rattle.

    In the end that 'ol bruiser ended up going to a good cause ... a pseudo chook shed.

    And don't be shy about finding noises on the vehicle too.
    I started hearing a rattly metallic sound coming from under and the rear of mine after my recent drive.
    To me it sounds like a loose-ish brake cover doodad(which reminds me .. must pulls wheels and check brakes this coming week too).

    Hey we did forget to go for a drive, and ran out of time haha next time for sure! Btw...HAPPY NEW YEAR!

    Yeah it seems like I might be jumping at shadows and trying to make the old girl sound like a brand new car. I guess it was just a noise that I hadn't heard before and then it popped up so it bothered me, sounds like I'm on to a good thing though and I think I need a few other Disco diesels for a baseline comparison haha

    Yeah I used to drive a 90s hilux diesel for work, damn noisy thing and not a lot of go either, pretty indestructible though, used to flog the heck out of it and do big paddock surveys through thick mud and it got through most things, it's easier when it's not your car haha one time it just stopped and thew a bunch of warning lights up and we popped the bonnet and there was a couple of belts that had just snapped which we could take out of the engine bay and hang around our necks and pose for photos to show the bosses...don't think they were too impressed but we thought we were pretty funny

    Those muddies sure do drive nicely, I did had a bit of a skiddy moment while driving back from your place in that storm though when I thought I was going to go straight into the gutter, pretty sure that was the big lugs on the slippery road, that's just me having to be a bit more conservative and remember they're not really road tyres even though they are quiet and are a silica compound and have a couple of sipes etc. etc. still they are a great driving aggressive tyre and damn reliable too from all I've read.

    Found another noise the other morning too, seems like it's half the fun with these cars, this one sounded like a squeaky pulley which died down after the car warmed up, shouldn't be too hard to find that one.

    New year, new leak and new noise, wouldn't have it any other way

    Mine fan bearing in timing cover does that. Probably my fault from when i did the timing belt and cleaned the cover.

    So the other day(NY eve) after work, and again today whilst waiting for the kids to come over .. I was having a quick squizz in the engine bay to see if anything obvious was causing this annoying tinny rattle in mine.
    To me sounds like rear .. eg. like a loose rear brake guard rattling .. but thought to check the engine bay .. check oil and coolant levels, and trans colour(at least .. level another day) .. just quick easy stuff that doesn't require the use of grey matter.

    So I've also found an oil leak. Mine seems to be coming from the vacuum pump, or it's gasket.
    It's not really a leak, but it's a spraying of oil that seemed to have stopped. a bit of oil under the car, but no oil leaks(drops).

    So now I'm thinking is my oil leak and rattle a coincidence, or are they related?

    I remember yours was fuel pump and back, whereas mine is vacuum pump and down(a little) sprayed under car .. and no current drips(driveway clean). The oil slick under the car also doesn't extend too far back, seems to stop at about the cross member, or front of transfer case .. so at least it's not an ongoing issue(which is going to make finding the source a lot harder)
    Checking oil level AGAIN .. to confirm that I saw it was still at the top mark .. confirmed that it was indeed level at the top mark.
    So .... it's lost oil that it hasn't quite lost

    I'm theorising it this way: Over the years I reckon I've had about 25 Rover vehicles of various types, and all of them have had oil leaks one way or another.
    If not the engine seals, then the power steering pump, lines, reservoir, and even the bottle of top up fluid kept in the engine bay for ease of access.
    Either way, oil has always escaped the item created to contain it, be that an engine, or reservoir, or gearbox .. or even the bottle that wasn't a Rover created item, just being in the vicinity of a Rover product has educated this bottle of (Shell, I think) power steering fluid to know how to act in the presence of an aristocratic vehicle!

    This D1 tho, has me confounded(and IT knows this) .. other than my one muck up with he front main seal, it's never really dropped a single drop of fluid of any type in the 18months I've known it.
    So it knows this, it understands that in my current delirium .. and therefore an ongoing inability to compute the terms 'Rover' and 'oil leak' as anything other than two mutually inclusive terms .. it's felt sorry for me, and helping come to grips that my preconception may be incorrect.
    So it's doing this temporary thing .. leaking a little, just enough to show me that they still do leak, but then stops, for the purpose of re-educating me that maybe they don't always all leak, and that I need to do discard my old preconceptions and experiences of yester-yester-year.

    That sounds like the start to the Australian Land Rover Owners Memoirs

    The old girl is just looking out for you, making sure you're not going too crazy...great theory!

    Nah! If I related my other theory here without taking the topic on a wild tangent .. you'd understand that the old girls job is a wasted effort!
    My state of mind is well beyond the 'too crazy' point of no return.
    On the odd occasion tho, She has been the reason I've regressed a little backwards from the beyond state and back into the 'too crazy' state.
    For a few moments this morning I progressed forward, and beyond, again with thoughts on how to shoehorn another unwanted D2! .. into the limited space at my place(knowing that I have a shed to build in the coming months and a house to renovate one day too).
