    Fitted pro vent to td5

    The point I was tentatively making is that Many think that the valve in a Provent can replace the valve.

    First I have never seen specs on the manifold depression required to shut the valve or even if the valve is a CDV.
    After having a look at my fake one a week ago, I wondered if it was actually a relief/bypass valve for when the filter became blocked. In other words the opposite of a CDV. Can anyone confirm the function of the valve? I cannot recall it's function in the specs as listed on the Mann Hummel site.
    In the meantime I have left my CDV alone.

    Ah! Now I understand where you’re coming from... on a Provent 100 / Flashlube Catch Can Pro and presumably their clones - the bottom side vent near the inlet pipe is the pressure relief value and the top vent above the outlet pipe is the vacuum relief valve. When the filter blocks both vents open to atmosphere.

    My problem is that I have no place on the left side only on the right (my car is LHD) which means much longer pipes and more difficult routing.Attachment 153530
    Sorry for late reply. I fitted the “catch can” because it catches the oil before it gets into the intercooler and pipes, which effects performance. I’m sure theirs other reasons but my motor passed a lot of oil through.

    I added mine to improve the air getting into the engine, and to extend the inter cooler cleaning kms up to 380k kms

    Before I had a Land Rover I did not have any torque wrenches. Now I have three.
