Inlet manifold questions

Hi all,
         a few questions with regards to standard 2L 32/36 inlet manifolds. Im replacing the messed up one on my car.
  Firstly, does the inlet manifold gasket require any sealant on it or do most people fit it dry ? the gregorys manual says to use some around the coolant passage but Im thinking if you're going to do a little bit you may as well do the whole gasket.
   Secondly , one of the manifold studs was loose and backed out with the nut when removing the manifold mount nuts , effectively making it a bolt ! Are these studs loctited into the head?
 When fitting the carb to the manifold is it customary to use a gasket on both sides of the Bakelite spacer beneath the carb?
              Cheers

    i have always used loctite master gasket 518 for all gaskets, and there thread locker, to stop the rattling out.

    hi,
    #sealant around water passage only.
    #studs aren't loctited, but the stud thread at nut end  is either damaged or **** type of locking nut used. replace with undamaged stud
      and/or appropriate non locking nut.
    #gasket both sides of carby spacer. If surfaces serviceable no sealant needed.

    Yeah it had nyloc nuts which I thought were the wrong type of nut for an inlet manifold. I vaguely recall on all my other escorts having normal nuts with spring washers..
    When installing a stud do you use double nuts locked up on each other to screw  it in till tight then remove the nuts ?

    Yep that's fine, you should see unthreaded part of stud bottom out and go tight.

    Cheers

    you could also replace the nuts with a "cone nut" as it has the same principle as a nyloc but with out the nylon
