Gasket Materials
Evening folks,
Last week I re attached my intake manifold. Making a new gasket as the old one broke/ripped/snapped.
Now I thought the material I used was gasket stuff but it turns out its the worlds best absorber and transporter of water.
And as the water flows though one of the holes, this is a problem.
Now I could just order one new off ebay, ~£10 and 2 weeks wait or I could have another go with a different material.
So really I have 2 questions, what is a good material, where can I get some locally on a saturday?
I had another idea, would aluminium sheet work? I have plenty of ~0.8mm sheet left over.
Or would I never be able to clamp it down enough to seal?
Thought and suggestions welcome...

Normally ordinary thick cartridge paper works fine for gaskets that run up to boiling water temperature.
Could the manifold nuts be coil bound on the studs ?.

A decent motor factor should be able to sell you proper gasket paper

Good point, ill make sure the studs are actually doing there job.
Any thoughts on aluminum?

Gasket material needs to deform in order to seal, which means the parts either side need to be a stronger material and the clamping forces need to be
sufficient to crush the gasket at least a little bit. I don't know what you're using for a manifold, i would be surprised if it met both
requirements.
I've only really experienced metal head gaskets, consider how tightly they're fitted. Are you angle tightening your manifold nuts for
example?

Erm, i used angle tightening as an example to apply sufficient clamping force, not sure it would have been appropriate for an inlet manifold. Sorry.

No need to apologise, the nuts and studs were indeed not allowing the correct clamping force for the torque. Some cleaning and proper tightening was
the key. Thanks!
