I have done a PCV simplification and am very happy with the results. A lot of goo and gunk stays out of my engine, all for the better.
In short:
From oil filter housing (90 degree turn) straight to the Y pipe which connects to the rocker cover. The Y pipe is connected to another long piece of hose which ends under the car next to the exhaust.
My MOT is due, I will connect the original system again and will remove it again after testing
