The connection to the rocker cover is shown in the 2nd pic.
To replace the existing cyclone on a 300Tdi with a Provent, would entail making a fitting to suit the rocker cover.
IMHO the testing that we are doing for Ben would be compromised if the Provent was installed after the existing cyclone separator. Ben might like to comment.
