    Question Question about PCV breather system, replace or clean? 04XC70

    I have been contemplating replacing the whole PCV breather system currently selling from IPD for about $360.00 which comes with all the lines, oil trap canister, etc.. I would like to know if it is possible to just clean the lines, canister, etc., and save a bunch, Or just replace the whole thing?

    You need to replace most of the parts
    The lerge line, the one that costs $200, can be played with but you need to know exactly what to do

    Chiming in here because I just did my 2004 over the holidays in my freezing driveway. Don't cheap out and try to clean it. Sure, some of the various pipes and connectors could be cleaned, but at this age, everything is getting brittle. And you're gonna have everything apart anyway.
    BTW- the same kit at FCP Euro is $284.00.
    Tips: Just drain the coolant and replace it with nice fresh Volvo blue coolant at the end of the job. This saves you a whole lot of grief, and you probably need to do it anyway.
    Related to above: You will need a new thermostat housing gasket, because you will spend WAY too much time trying to tighten the far left manifold bolt if you don't, and you will wonder why the heck you didn't just take the dang thermostat off and do it properly!
    Make sure you have an assortment of copper washers on hand to seal the two banjo bolts. There are two on each, and I lost at least one washer on each while trying to thread them (by far, the worst part of the job).
    Happy Wrenching!

    Of course. I remove my entire PCV system at 125K mi and cleaned it out with kerosene. I replaced some of the cheaper hoses that are directly attached to the engine block, they get brittle and crack. I did not replace the flame trap or the expensive oil vapor line from the flame trap to the intake. 80K miles later and the system is still functioning perfectly. I can't see how spending the extra $200 on replacement parts would have benefited in any way.

    Thumbs up I went ahead and did it!

    Well, I decided to go ahead and replace the breather system. Here is a summary of how it went.
    First, it took about 8 hours, 3 of which were spent either removing and putting back the banjo bolt (1), throttle body bolts (4), thermostats bolts (2) and taking pictures every so often.
    Second, removing those factory Volvo clamps were-- first, an annoyance, but the feeling escalated to a PITA!!!
    Third, in all the research I did, I never read a warning about the possibility of the computer needing a software re-installation which is needed after unplugging the throttle body cable. However, this was not the case. Phew!
    Lastly, I have to say, it is a lot of work, but manageable IF you are patience enough to figure things out.

    I will hopefully post my procedure on what I did and how I did it with pictures--thanks for the replies.

    Hi, for us, and future reference, do you know what would require a software reboot? So to be prepared for the cost at the dealer.

    RE boot?
    Nothing
    Once a used part is installed on a different P2 and initialized, that's it.
    It can be used on another car by just installing it.

    Except of course an ECU, but that too can now be worked around by Lucky at ARD tuning

    Good work on the breather repair/replacement.
    Did you end up getting the full kit and replacing the big/expensive oil vapor line too, or just do a good cleaning of that line.
    Pictures of your procedure would be awesome. I need to undertake this job when the weather warms up and any knowledge gleaned from your experience would be great.

    Please guys PCV not PVC

    PCV is Positive Crankcase Ventilation and it's what causes Volvo-grief.
    PVC is Poly Vinyl Chloride and it's a type of plastic.

    Of course some pieces of PCV might be made of PVC
