Replacing oil pan

[dalton1]

So I'm getting ready to do my oil pan and wanted to know if there is any thing else I should replace while I have the engine out thats not to expensive?
so far I'm planning on oil pan, glow plugs, up pipe gaskets, turbo pedestal o-rings.
what else is prone to failure/leaking while I have the engine out?
