Please help identify this hose leaking oil
Discussion
Does anyone know what this hose is that is leaking oil? Car in question is my 1999 mark 2 Seat Toledo 1.9 Tdi. I took the engine cover off and noticed the leak. Is it something that requires immediate attention or can I drive it for the moment? I don't think it's a big leak - I've not noticed any oil on the floor.
Any help appreciated.

As above, nothing to worry about - just a breather hose as stated.
It carries basically air that's displaced in the engine as a result of the pistons moving up and down - the air being pushed down with the piston on each stroke has to go somewhere, hence the top of the engine has a hole with a breather hose to allow this air to move away.
Within that air though is also a 'mist' of oil vapour - so the hose is connected to the engine's inlet to recycle the vapour.
So when the breather hose gets a bit tired, as yours has, you'll get a bit of oil mist / vapour leaking out.
The fix in your case is to buy a jubilee clip of the right size for that hose, and clamp it round the hose where it plugs onto the inlet, where it's leaking.
