Rubber Seal/gasket On Plenum?

[Ruxis]

Hey guys,

i can hear from what sounds like a noisy valve in the plenum/intake manifold. before i take my daily apart i wa wondering are there rubber seals there or will i need to buy/make a new gasket?

its a 2000 model so if its a rubber seal maybe i wont need to replace it?

if i do where would be a good place to get one?? (NSW)

intake manifold gasket is a steel gasket from memory (at the head) and a rubber gasket between the runners and top half of the manifold

I would buy either or both from Nissan or someone who stocks Nissan genuine parts (eg Just Jap)
