turbo noises

Discussion in 'alt.fan.landrover' started by Richard Wilkinson, May 31, 2006.

  1. Recently the turbo on my 96 disco has started making a kind of sucking,
    whining noise when the engine revvs reach 2000 and above - almost sounds
    like theres a vacuum cleaner under my bonnet speeding up!

    I havn't noticed any loss of power and its not terribly noisy, but certainly
    noticeable. It seems to have started happening around the time I changed
    the air filter (which was pretty dirty) - could it just be the engine is
    breathing better?

    I only ask after having read Gary Jones' catastrophic problems a blown up
    turbo had on the rest of his engine! I don't really want mine to go the
    same way.

    Also, I have noticed there is a bit of white smoke coming out of the exhaust
    when I start the engine. I would expect some black smoke, but I don't know
    what white smoke signals, if anything.

    Any info would be great!

    I love the sound of a turbo diesel ( I have to the miles I put in)- changes
    after a new air filter I would be looking at the pipes for splits around
    the filter box and checking the filter seated correctly and the clips didn't
    pop open if its a sucking sort of noise not a bad idea to get a partner to
    hold the throttle open while you have a listen under the bonnet to work out
    whereabouts the noise originates as splits often hide from view till
    provoked.

    I'm fairly sure that white smoke from a diesel is unburnt fuel (or
    oil...).

    Had a similar noise to OP which turned out to be a split in the right angle
    hose between turbo and inlet manifold, at the bottom of the turbo. Hard to
    spot from above, needed a mirror to see it and only then when turbo in
    boost. Small split - big noise - bad thoughts about lots of dollars , but
    15min to pull out and replace and problem solvered.

    Cheers

  6. Yikes,

    Okay white smoke could be turbo bearings on the way out. Another scarey
    thought is head gasket. Has it overheated at all? If it has then I am
    certain you are looking at an ill turbo.

    You need to get the turbo tested.

    If I am honest I think your turbo is ill.

    Yours

    Andy

    Smell the smoke - both unburnt fuel(usually associated with white smoke)
    and oil (more usually associated with blue smoke) have distinctive
    smells. It's not just water vapour (innocent or otherwise)is it?.

    Like already said, get everything checked out asap, mine did not make any
    unusual noises at all before meltdown. Still dont know for sure what went
    first, the head gasket, or the turbo followed close by by various engine
    parts, whatever it was it all took less tha 15 seconds or so.
    If all else fails carry a can of petrol in the back, a box of matches and if
    it goes like mine, use the petrol and the matches then runaway.
    When back home call the insurance and tell them it was nicked.
    :eek:) If only.
    Cheers Gary

    Marge (110TD) always clears her through after starting with a good white
    fogbank, but after she's warmed up there's almost nothing, even under
    heavy load. I think it's the Defender equivalent of smoker's cough...

    .... but I put it down to the tolerances being off until the turbo has
    warmed through thoroughly. Hope I'm right :-o
