No it is sealed by an O'ring.
Necropost FTW.
Just some info on the EGR, you said remove the vac pipe where it attaches to the articulator. Do I need to plug the vac pipe with anything or just tie it out of the way and let it suck air from atmo? I decided to have a butchers at mine today, wasn't too cake, but figured I'd disable it anyway.

Yep, pull it at the EGR diaphragm and plug the pipe (not the EGR) with a screw
Thought so, lets see how much difference that makes to the coking up of the EGR. Intercooler needs to be cleaned up next. Dirty dirty diesels.

If EGR is never open it can't coke up. But the intercooler contamination can be significantly reduced by cleaning out the oil separator and valve in the cam cover.
That was going to be my next query as it seems to spit a lot of oil into the intake. I will soon have an uberclean derv.
Ta muchly good sir.

I've not being able to find my oil separator. The diagrams in Rave didn't help. I know it must be really obvious to the mechanics out there. I know what the spiral thing looks like, I just don't know where it is!
Someone take a piccy for me

The plastic manifolds don't have one the oil mist is sucked strait In,Via the air intake that goes above the engine

So I don't have one on a 2002? That would explain my lack of success...

Look at your rocker cover the little black tube goes into the air intake system without any filteration!
Unlike early versions

All diesels have an oil separator and PCV inside the cam cover. Remove the cam cover and the PCV and oil separator gauze can be removed and cleaned.

I seem to be getting the same MPG figures as you. Is there a reason why I am getting less MPG in colder weather than I did in the summer?

Take the cam cover off if you must but you won't find anything in there apart from the cam the rubber cam cover gasket and the hole for the rubber tube that goes into the air intake . As you can see from this picture 14 is the old type with an oil trap that sits on the outside of the cam cover and the later type just have a hose number 21 no trap

Have you had the cam cover off? As far as I'm aware Wammers is correct on this one, there is an oil seperator in there. No way would it just be a pipe to a hole in the cam cover as there would be loads of oil mist sucked into the intake.Take the cam cover off if you must but you won't find anything in there apart from the cam the rubber cam cover gasket and the hole for the rubber tube that goes into the air intake .

Others have reported cleaning the seperator, never done it myself but it's on the to do list.

Yes I have to change the cam cover gasket .
Show me the part numbers for this so called seperator.
yes the later ones its just a tube from the cam cover to the air intake tube the
Non egr ones have a little filter bowl that sits on the outside that can be cleaned and goes inline between the air intake tube and the cam cover.

Sounds like yours has an early cam cover then. My early one has the external filter, as far as I'm aware, later ones have the internal seperator. Happy to be proved wrong as it would knock a job off the list but others have reported cleaning it.
Get enough oil vapour into the intake and the engine will run out of control on it.

Good point data I have the early type head fitted to mine .Sounds like yours has an early cam cover then.

This is the early type seperator itself .
So yes maybe mine should have a gauze around the hole but I've not seen one just a hole the pipe and that's it .
I've run this car for 30 k now and it will take more than a few misty vapours for a runaway engine

It's more than a bit of gauze round the hole and engines will run away on oil mist if there is enough. I'd fit the external one if I was you.Good point data I have the early type head fitted to mine .
