Just took off the breather hose which connects the airbox thing on top of the throttle body to the engine block and it's full of yellow gunky stuff, almost blocking the tube.
Usual or should I clean it, what with?
Ta!

done my best to clean it.
does having the pipe clogged up affect performance/running.

tbh its not really needed, i fitted mine as i got it free, some information can be found here:
http://corsasport.co.uk/board/viewthread.php?tid=215575
The cam cover breather pipes ae connected to the induction system of the X and Z 1.2XE engines via the top hat, and under hard driving conditions oil sludge can be drawn up this pipe and into the induction system. The engine was designed like this so that any oil vapours released by the engine would be combusted, but the down side is oil collecting in the throttle and induction system. This can lead to fouling of the injectors, giving a poor spray pattern and gumming up of the passageways in the throttle. The manifold is designed so that any oil that might collect in the plenym stays there and does not trickle down the header pipes to the ports. This could be prevented by fitting a breather filter by pipercross, the connection on the top hat would have to be blanked off to stop unfiltered air entering the induction system. This may or may not have a slight effect on the flow meter depending on how much air was drawn through the breather line.
and that from http://corsasport.co.uk/board/viewthread.php?tid=41366

the breather tube can quite often get clogged up because water vapour gets in.

Better to vent the vapour to atmosphere and clean the pipe out every few weeks, whenever you wash the car, check tyre pressures, check your bulbs are working, etc.
Just routine checks/maintenance.

only better because oil capour lowers octane rating but not legal though it is

A gunky crankcase hose is the least of your worries
