Does N53 330i have a CCV/PCV valve?

Hi,

I'm a little confused about EGR blanking and CCV/PCV catch can. I've got a few questions:

1. Wouldn't EGR blanking make a PCV catch can unnecessary?
2. Do petrol engines, and in particular N53 330i have an EGR valve?
3. Does the N53 330i have a PCV valve?

I am asking the last two because I can't seem to find the PCV valve on the BMW parts page:

So I thought, perhaps the N53 330i does not have a CCV/PCV, as strange as it sounds.

1. Wouldn't EGR blanking make a PCV catch can unnecessary? Personally I wouldn't fully blank the EGR as you will get codes. I partially blanked mine so there was still a small amount of gas flow. I also have an OCC and it catches plenty of liquid.
2. Do petrol engines, and in particular N53 330i have an EGR valve? Yes.
3. Does the N53 330i have a PCV valve? Yes - it's incorporated in the valve cover.
