anyone replaced their PCV valve?

[tmg]

I have a weeping pcv a tthe back of the engine (some oil tricking down onto the gearbox bell housing etc)

nothing mad, but its poking my ocd

so has anyone done this before? the only hesitation I have is its quite cramped, and i dont know how long the breather hose is (as in can you lift it out and reclamp, or is it a mega faff). seems straightforward enough to get the PCV off (two bolts) but not sure about clamp, and how to re-attach it etc.
