Version #1 involved increasing the diameter of two orifices by drilling them out. The orifice on the oil trap was to be increased to 5mm (originally 3.5mm or something in that range). You have to get under the car and remove the oil trap to inspect the orifice size.

It also specified increasing the size of the bore of the small barb fitting on the bottom of the PCV fitting (the one going into the valve cover) to 2.5mm. You can probably pull this part off without tools to inspect it and probe with a drill bit which matches 2.5mm in size, ~3/32 inch.

But Version #2 is the currently recommended repair so I wouldn't worry whether or not Version #1 was performed. These changes were recommended to prevent excessive internal engine cranckcase pressures. Too great of pressure can cause oil leaks past the engine seals. My past experience with industrial pumps has been that once a non-adjustable seal starts to weep, it needs to be replaced. That is why I consider this to be a preventive measure - one you want to do before the oil leakage starts.
