Things to replace once re-fitting intake manifold on m20b25

Hi,
I'm wondering what other parts need replacing besides the manifold gasket it self? Part numbers will be helpful to so i can get a price on here also!
Thanks

It's manifold gaskets - there three of them. Throttle body gasket should be replaced (but is often reusable), the O rings on the spring loaded oil tube need replacing, and the injectors need new O rings if they've been removed.
If the injectors have been sent for reconditioning, they will normally be returned complete with new O rings.
There's also a gasket for the thermostat elbow, if that has been removed.

Thanks, will most likely send the injectors of for reconditioning, seen a fellow zoner who does that on here, is it best to order all the gaskets etc from dealers? Also is it essential to remove the thermostat once taking the intake of?

No, you shouldn't need to take it off to get the inlet manifold off. However, whilst in there with so much easy access it's a good time to change that as well, sods law a few months down the line it'll end up leaking.
