[Saloon-lovers] Removing the Intake manifold safely 3.4lt S Type

I have recently removed the head from my motor as part of a rebuild
process. I need to remove the intake manifold from the head and as
is often the case it is proving very stubborn. Has anyone ideas as
to how to safely remove the manifold. I suspect that a previous
owner has used some kind of glue when last fitting the manifold.–

Get as many studs out as possible, using 2 nuts.

you can try grinding the nuts a bit to make them thinner.

the ones you cant get out, soak in penetrating oil

strike the manifold with a rubber mallet

as an absolute last resort, you can drill the offending stud

I did this job on 2 heads recently, and had no joy at all
until I removed nearly all the studs.

the problem is the bi-metallic corrosion and coolant form a
whitish paste that is effectively a damm good glue for the
studs to the manifold

unavailable studs can be remade if neccesary using threaded rod–

I have had the same problem, corosion between the stud and the
aluminum manifold. In addition to removing the studs that you can, I
made a small stud press out of a threaded rod coupling and a bolt.
There are places you can insert this piece between the head and the
underside of the manifolt, then screw the bolt out of the rod coupling
to press the manifold off. Once you get it to move, you have it made.

Thanks John, sounds like it could help. A friend of mine broke his
manifold in half trying to get it off so I am being rather
cautious. Plutos–

Thanks for the help on this topic.
I was successful today in removing the manifold in one piece. In
the end I did not need to remove studs. A helpful hint for others
however, what I did was use a stanley knife in the gap to create
enough opportunity to get some penetrating fluid (WD40)into contact
with the gasket after scaping out what I could of the gasket with
the knife I soaked the gap with WD40 over night and this did the
trick allowing me to remove the manifold reasonably easily this
morning. Maybe I was just lucky. - Plutos–
