Ok been to Tollbar Volvo and they sent me this....
www.tarmacsurfer.co.uk/PCV%20parts.pdf thought it might be of interest to others with the same engine for parts requests?
Comes to about £75 excluding the Volvo clips (I will use jubilees much easier!). I am not sure I need all the hoses but I will discuss this with them tomorrow to what is best...yet again very helpful at Tollbar!
