    Re: removal of manifold

    I would get a new head gasket and do the lot. I can't imagine the manifolds are much fun to remove with the head in situ.

    Lol.. Only kidding mate

    Does the Haynes Manual not have a write up on it? Personally, I wouldn't change the headgasket whilst doing the Manifold if you haven't blown the headgasket.

    Re: removal of manifold

    I agree not an easy task to undo the bolts to the manifold with head/engine in place. Remove engine or head to do. Unless you want to try with it in place. More than likely easy to remove downpipe to get easier access to the bolts and insert socket to undo. Good luck there though

    Re: removal of manifold

    I could have sworn I took my manifold off before the head, when I changed a headgasket on my old GTT. Might be wrong though

    That would have been a very awkward way of doing the head gasket

    Re: removal of manifold

    I think it can be done but bet it's a right bastid. For the sake of a £20 head gasket and a bit more work it'll save a lot of stress.

    Re: removal of manifold

    I always do the inlet/exhaust manifold gasket in situ, don't disturb the head gasket unless its necessary, more expense imo. Easy enough job to do just time consuming.

    Re: removal of manifold

    I have removed the manifolds whilst engine is in situ it is a pain in the arse but if you have got child like hands like me and not big sausage mits you have a little more room to manouvere and get to the awkward nuts.

    Re: removal of manifold

    A decent ratchet spanner always helps with the awkward nuts

    Whilst your doing it id fit some spring washers/decent locking nuts on aswell, the manifold gaskets usually go due to the nuts coming loose imo. Also be careful if the studs withdraw themselves from the head, its easy to cross/knack the thread refitting them, a tap set comes in handy to chase/clean the threads out.

    Remove turbo, carb, throttle cable, boost hoses etc. If that ain't enough advice get a haynes manual

    Re: removal of manifold

    • take the carb off.
    • remove boost hoses
    • remove all inlet manifold pipes.
    • remove the plate that sits on the inlet man and also the 2 bits that sit ontop of the plate.
    • undo the downpipe from turbo elbow
    • undo the nuts that secure the inlet manilfold to the head first[will give you more room]
    • undo the ex man nuts.
    • take manifold gasket off.
    • clean surfaces,making sure no old gasket is left anywhere.[i do this by removing the manifold studs and running a stanley blade across the head & manifolds surface]

    • refit in reverse order.

    Re: removal of manifold

    I always take the turbo off, as the oil feed/return always need to be disconnected, its only 4 more nuts & makes it a lot easier to lift the manifold out

    If your doing it with the head in situ as you say then you'll need to get at it from top, side, front, back, bottom, inside, outside, under, over......... it's a right pain in the arse.
    You'll get the first 6 bolts out no worries, then for the rest you'll either wish you had taken the head off, or wish you had 4 wrists on one arm so you can get the spanner in under the exhaust man' and above the starter heat shield. Good luck

    Re: removal of manifold

    It sure is a nightmare... one of the first things I did completely on my own, without the help of a mechanic, was changing the standard exhaust manifold with a tubular manifold. And I left the head in place! It's doable, but probably better to take the head off

    Re: removal of manifold

    Honestly its not as bad as you think, for the arkward bolts i use a small 13mm socket on an extension which gets to them easily and the 2 under the carb are easy to get to with a 13mm spanner.

    Do take everything off the manifold as it makes it easier to work round but apart from that the hardest part wil be if you had a siezed bolt/nut.
