I took my engine cover off to change my oil and seems to be a load of oil seeped out at back of engine

is this something to be worries about

car is a tdi asv

It looks like the problem is part number 038 103 493 P VAG Hose, cylinder head cover breather.  Initially I'd give it a good clean and then check on a regular basis to confirm where the oil is misting from.  You may also be able to smell the sour engine oil smell in the cabin.

BTW your forum details are showing as a 2006 mk2 Octavia, not a mk1.  Is this correct?

 

Thanks, sorry thats my old car i will update.

not been smelling any smells but will give it a clean and see how it goes. 

Is that breather pushed home until it clicks into place on the inlet tract pipe thing? Looks like it's sitting a little ways off to me?
