    Default Fitting a Provent Catch Can to a diesel

    I am thinking of fitting one of these to our 2012 Jeep Grand Cherokee. Has any one fitted on to their diesel as it is supposed to help with economy plus keep the engine clean. See https://youtu.be/f4_dW98oJ1A Here is the video for fitting the unit into a post 2011 Jeep Grand Cherokee. https://www.youtube.com/watch?v=UPBPNN5RGlU

    The only economic saving is going to be salvaging the oil that would normally be drawn into the intake and burnt.

    I'm in the middle of making a catch can for my D2, because at 360k it has a blowby problem and the inlet manifold is always wet inside with oil.
    Cheers,
    John

    Plus the turbo pipes will not be softened and eventually fail at some stage due to the effect of the oil.

    I have been looking into this for some time now. Noticed on Youtube the Ausies rate this as a decent upgrade.

    Which brand/type is better/more cost effective?

    Have seen these at our local "racing" supply shop

    I would also be interested to know if anybody has used the Provent product. Considering fitting one to my Pathfinder but it looks like I am going to have to have it shipped from Oz/US. Installation looks pretty straigforward, and looks more stock than the blingy items I have been able to find locally.

    If you do enough googling, there was one of the Isuzu's that had a catch can fitted as standard...

    I bought one (the local ones mentioned) for my C180 as the old lady is starting to breathe and makes the engine bay look awful...however I haven't been able to fit it as there is no space in the engine bay...

    In some material I have read, it appears that a correctly-installed Provent might allow service intervals to be extended, especially on older IDI diesel engines.

    The idea is that if you can create sufficient vacuum in the crank-case, then the dirty gasses leaking past the rings will be drawn through the catch-can and either filtered out or returned to the gas stream.

    I would want to look at oil analysis before actually extending service intervals myself though...
