V6 spark plugs - bit of a job!

    I thought Subarus were a pain in the neck with a flat four and having to
    remove half the gubbins on each side of the engine to get to the plugs!

    However, my 69500 mile 406 V6 was a bit reluctant below 4000 RPM so I bought
    (2x4 pack :( ) plugs. Front bank is easy under the engine cover and the coil
    packs lift off.

    But to do the rear bank I had to remove the whole inlet
    manifold/plenum/throttle body!

    Masterpiece of design there Peugeot. Are all V6s like this - I've never
    really looked.

    Good news it that there is now a much smoother performance below 4000 RPM
    with no sudden wild cam feel at 4000 RPM, but much more torque below.

  2. Is it a difficult job, apart from being a pain in the arse ? I've thought
    about doing mine (spend a lot of time working on my racebike, so I'm pretty
    mechanical), but I'm curious how big a job it is.

    Well I did the wife's Puma first and that took 15 minutes. This took 90
    minutes. Not difficult, just rather cold doing it when the temperature was 3
    degrees.

    If you are doing it I suggest getting a new inlet manifold gasket. Mine
    split in a few places and I ended up using sealant. It is not leaking, (not
    like it is under boost or anything ;) ), and where it split and was adherent
    to the inlet manifold the other matching part was still adherent to the
    block.
