    You may have seen my earlier posting "1991 605 head gasket gone - DIY or
    junk the car?"
    Well, I decided on DIY and I'm now beginning to collect bits of engine
    all over the garage floor...

    So - first problem for your assistance (there will be many more, I'm sure):

    Spec: 605 SLi, 1998cc, injection, 8 valve, XU10 RFZ engine

    How to detach the exhaust manifold from the exhaust front pipe?

    Exhaust attaches to manifold at rear of engine. (or rear side as its
    transverse, but you know what I mean)
    There is about a two inch gap between the engine and the bulk-head. The
    exhaust manifold bolts are too rusty to remove, and there's not enough
    room back there to swing a spanner anyway. So obvious thing to do is
    leave the manifold on the head and detach the exhaust front pipe.
    Manifold is attached to exhaust front pipe via a big flange and two
    sprung bolts. Not a simple nut-and-bolt arrangement, there are these
    spring things. Impossible to attack it from above as there's so little
    room behind the engine. Impossible to get to it from below as there's
    all kinds of suspension and cross-beams in the way. Apparently (I'm
    guessing) Peugeot saw the problem, and fitted these sprung bolts which
    fit into slots (not holes) on the manifold side - some kind of
    quick-release mechansim, but I'm stuffed if I can figure out how to
    release the front pipe from the manifold.

    I know there any not many 605s in the world, but anybody out there got
    one and done this ?

    10mm spanner on top (single hex)
    10mm socket from underneath (again single hex)
    they round very easily
    if unable to remove this way then cut them off through the spring with a
    and obtain a flange fitting kit which includes the bolts nuts seal springs
    washers etc

    OK - I'll give it another go this weekend. I have no idea how I'm going
    to get a spanner/ saw / blowtorch into that tiny space.

    I'll give an update on Sunday... and then (hopefully) it will be on to
    Problem Number 2, which I suspect will be how to get the timing belt
    cover off without removing the O/S top engine mounting... but let's deal
    with one problem at a time.

  4. Hi

    Peugeot part number 1798 75 exhaust fixing kit / downpipe repair kit is
    what you are after, Last one I bought from a Pug dealer was around £17,
    Comes in kit form with all the bolts, springs, nuts etc you need.

    I did it!
    It didn't need spanners, saw or blow-torch.
    What it needed was a long screwdriver, a really big hammer and lots of
    rust. A few well-aimed blows on the very rusty "cups" over the spring
    ends amd it all fell apart....
