Excessive oil consumption. PCV valve? 2017 Peugeot Boxer Euro 6 2.0 Blue HDi 130 (96kw / 130cv)

[TheEuroWombat]

I have a 2017 Peugeot Boxer Euro 6 2.0 Blue HDi 130 (96kw / 130cv) and it is consuming an excessive amount of oil (5ltrs in 800km).

There is no leak and no smoke.

I’ve read a few things online which suggest checking the PCV valve (I’ve also read that diesel engines have a CCV not PCV?)
Other than this I can’t find much information about it or a replacement part anywhere.

Can anyone point me in the direction of where I will find this in the engine bay and where I could source a replacement part?
and if anyone has any good advice, videos or resources on how to check / replace this that would be amazing.

I've had to top up with 6ltrs in just over 3 weeks. No real signs of any major leak on the floor and I've got no smoke coming out the exhaust.

Engine performance had been fine, up until about 2 days ago. Now I'm starting to notice a big of 'lag' in acceleration when I go to pull away. Could all this be linked and does that point to what might be the cause?

Here is a photo of my engine bay, are you able to point out to me here I should be looking for the things you mentioned in your reply



Thanks

Excessive oil consumption is very common on this engine and i know Peugeot replace loads of engines for this fault.
Have you done basic checks like the turbo?
