I looked up your car the best I could being my parts catalog(I work in parts at a GM Dealership) is for US models mainly. But It looks like their in't a PCV valve. Its possible it's a fixed orifice.
Here is anything that is related to the PCV system. its just hoses.
Hope this helps you out.
edit: I just noticed this is for a 1.6L forgin car. If I can get the last 8 digits of the vin number I might be able to look it up better.
