    Default Crank case vent

    OK now I have been running a modified CCV (as per Winnie2457 lengthy post on the subject) venting through a small metal filter adjacent to but just above the ARB, for about 2,000 miles now and can report that the intake system is totally immaculate not had any fume ingress and not had any increase in oil consumption.

    I think I am going to leave the set up alone for now and call it a success!

    Just to back you up there derek mine been on 5000 miles now and no loss of oil and intake dry as a bone no oil or cruddy build up I am now the same as you venting through a small metal breather next to the arb

    Only good results so far and I am suprised the amount of fumes and smoke and heat that comes from re breather no wonder your intake manifold is
    clogged up an you get less mpg with it connected due to the heat and smoke meaning less cool fresh air

    Any one else to report on this mod I knownthere are a few other ppl who hve tried it out

    I would like to try this, but would need an idiots guide to how to do it... any takers...?

    Definitely this and EGR blanking is a must on the CDTi for longevity.

    EGR valve is a blanking for me @ remap time but as for the oil catch tank - well my luck being my luck I would endup disturbing something and awakening a load of grief, but I will deffo say the oil catch tank idea is a peach of an idea.

    No Problems can do a photo how to if you like?

    I also plan on the Fiat restricted gaskets shortly too.


    As for economy it is up from 50.4 to 51.3 in similar motoring so seems not to have any negative impact on fuel

    That would be great mate.

    Same with me with the completely blanked EGR, slight increase in mpg has been the result, used to scrape 60 on a long motorway run, but can now get low 60's every time

    OK, I have borrowed a pic from Winnie2457's post to illustrate what I am talking about.

    1. Remove the pipe that exits from the oil separator that goes in to the metal crossover pipe remove it and replace it turned round to give clearance to the extension you are about to add. Use a jubilee clip to seal it back in the new position.

    2. Get hold of about 1m of 1/2" or 13mm oil/cooling type hose from a motor factor and a connector to join to the hose then route the pipe along the bulkhead and then down to the passenger side foot-well in my case just above the ARB so that fumes are not drawn in to the cabin and it doesn't get wet in a water "fording" situation as I used the height of the engine intake as a rule of thumb for this I am quite satisfied it "should" be alright.

    3. Blank off the pipe to the intake swan-neck I used a bolt at the front of the engine but equally a small piece of hose attached at the rear with a blanking plug will do as nicely and probably look more OEM as it will be hidden under the engine cover.

    4. I used cable ties to secure the pipe and prevent it rubbing and chaffing. At the end of the newly install a small filter to prevent anything walking up the pipe! I paid £3.65 off ebay! it looks the part is just visible in the last pic and is perfect for the job.

    5. Clean the EGR out and the intake as it really is amazing how the oil vapour combines with the soot to clog everything it touches.

    6. Time to stick the kettle on! have a brew and a Biccie once you have cleaned your hands that is!
