    Hi,
    I am in the South UK with one of the above which sounds like it has an
    intermittent misfire... cold cranking current is pretty even across all
    cylinders so I am wondering if it is a poor injector spray pattern and time
    for an injector overhaul ( 165,000 miles ) ?

    Economy still seems good at low to mid 40's to the UK gallon, but it sounds
    sick at idle and up to 2500 rpm, burns no oil between changes and is
    otherwise going well..

    If so, what is the least expensive path to get this done ? Overhaul or
    replace with new / re-furbed items and who does
    a good price ?

    Thanks,

    Nick

    Didnt you ask about this about 6 weeks ago?

    I think we said then that at 165k the injectors would be well past their
    best.

    I could also be time to replace the ignition leads. The long plastic tubes
    that pass into the spark plug wells have been known to break down and cause
    misfiring, that gradually gets worse. It's happened to me.

    Hi Baz,
    Should I also check the distributor cap and plugs ?
    Thanks,
    Nick

    In an earlier contribution to this discussion,
    It would be an interesting DIESEL engine (the clue is in the 'D' of 2.5D!)
    which had ignition leads and spark plugs!

    Indeed it is a diesel....

    Yes, Tim - I did ask about this a while back, and further looking into it
    still seems to point to injectors... however I "lost" my PC hard drive and
    couldn't remember any replies or if I had asked whether anyone could tell me
    where to get injectors re-furbed, or if new was the only option, so I
    repeated the query again in full, for any new readers, together with the
    request for info for places to get re-furbed, to give them the full
    picture... apologies for the part repetition...

    Thanks,
    Nick

    In an earlier contribution to this discussion,
    I don't know the answer but the engine is/was made by Audi, and the
    injectors are probably common to a lot of engines - and certainly not Volvo
    specific. So they'll almost certainly be cheaper if they're not in Volvo
    packaging.

    Look for a specialist Diesel service centre in your area. Yellow pages is
    your friend!

    Hi Roger,

    Thanks for the info so far - I have identified a local to me injector
    overhauler
    who will test for a fiver each and refurb for another £25 each which seems
    pretty fair...
    assuming it IS a single stage injector in these engines...

    You suggested I obtained a Haynes 3573 manual which I am having difficulty
    getting locally.

    The Halfords near me has a large number and I was wondering if you knew if
    this engine
    is used in another car (Audi?) where the engine info will be pretty much
    the same, and
    hopefully there will be a manual for that available on the shelf....

    Not having removed an injector before, I am wondering if I must do
    associated things, like
    replace any seals / washers... so I only really need the paragraph detailing
    the
    removal / replacement of the injectors (I think !)

    Thanks,
    Nick

    Sorry - another question or three if that's OK ?

    Just had a look at the injectors, with the aim of removal, and note the
    following:

    It looks like removal of the glowplug cables would make things easier - do
    these pull off?

    The retaining bolt on each injector is a 6mm Hex head socket cap situated in
    the middle of a "bridge",
    one side which seems to press/hold the injector into position, the other
    side on some sort of spacer -
    does this fall out or is it attached to the "cross member", and when
    removed, does the injector
    pull out or unscrew - I imagine it pulls out as otherwise there would be no
    need for the bolt / spacer etc.
    In that case is there an O ring or two on the body of the injector which
    will need replacing ?

    and (last query)

    the "master" injector with the cable - the connector at the difficult-to-see
    end, how does that unplug / come apart
    as it's very difficult to get at - do I have to remove the vacuum pump for
    access ?

    Thanks again,

    Nick

    In an earlier contribution to this discussion,

    Hi Nick,

    When I suggested getting a Haynes manual, it was in connection with things
    like brakes. The Haynes manual for the Volvo 70-series only covers petrol
    engines - so the diesel ain't in it unfortunately.

    If you send me a private email with a valid email address, I'll email you a
    page from the Volvo VADIS system, telling you how to change the injectors.
    [Post here to confirm that you've done it because, as per my sig, I don't
    look at gmail very often].

    In an earlier contribution to this discussion,
    I've never touched the injectors on my 1999 V70 2.5D, so don't have any
    direct experience. But see my other post.
