I've put 2.4 in the ***le but I'm sure the 2.0 will be the same.
After this valve was mentioned in another thread I decided to inspect it and the hose to check it's condition. You need to remove the 2 10mm silver nuts on top of the engine cover and then pull it off to see the entire hose.
The valve is located above the alternator to the right and the outer part is red.
You will have to release the spring clip and pull it back where the hose attached to the manifold and the valve can just be pulled out of the grommet it sits in. Then remove the hose from the PCV valve.

PCV Valve Grommet
With Grommet Removed
Hose - Manifold End
After pulling the grommet out, I noticed the rubber had gone quite hard. I cleaned all the oil out of the holder with some carb cleaner. I did try to remove this but it was fairly tight and I didn't want to risk snapping it.
I fitted a new grommet and new valve, both were a tight fit but I got them in without using lubrication. The old grommet obviously wasn't sealing very well cos I could pull it out very easily. If you do have to use something to get the valve back in then oil is recommended rather than something like washing up liquid!
The old hose had collapsed where it joins the manifold and looking inside there was only a slit as an opening so this wouldn't have been doing the engine any good.
New Grommet, Valve and Hose
New Hose
I had read that if the valve or hose is faulty it can lead to increased oil consumption as one of the symptoms. I tend to get through a lot of oil between changes, probably around 2 litres and the car does roughly 8k miles a year. I'll keep an eye on this and update if the consumption goes down.
Since fitting the new parts it seems to have cured (I hope) an issue I was having with the rev counter. When doing under 60mph and I lift off after accelerating the rev counter drops immediately to 500rpm (idle speed) and then rises. Now it drops more progressively and smoothly and not to 500rpm. I had put it down to an electrical gremlin as it didn't seem to affect how the car drove but it looks like this hose and/or valve was the culprit.
