    I've heard it won't pass visual inspection.

    So... not sure this thing will. But who knows?

    That doesn't look very friendly... for oil services.

    That is very interesting. I am actualy thinking to replace my CCV when it gets a bit warmer.
    Maybe I should wait for the release

    Interesting. I signed up on the email list. I would do it if it was black, and reasonably priced. Because if I can replace it just once that would be nice. The Radium catch can is expensive itself, and replacing the CCV over and over again expecting a different result is the definition of insanity.

    very interesting design. i've been waiting for this thing for a while, too! i like how it interfaces directly with the outlet on the valve cover and also the inlet on the intake manifold.

    also, it is a pretty cool packaging idea to mount it on top of the oil filter housing - that makes a lot of sense. i'm curious why they're draining back to the pan though, and not right into the oil filter housing?

    anyway, here is a link to the cool nerdy stuff (nate, i'm talking to you here ). all of my questions....save one... are answered here:

    this thing looks killer. i will most likely buy one. the one thing that does concern me - and this is my major beef with the CCV system - is freezing. i'm concerned that the condensate could still freeze. i will be contacting them about this.

    My impressions, from discussions with BMW Techs is that the condensate freezing is only an issue with lines that have buildup in them, as well as the frail lines that would break after the freeze, thus causing vacuum leaks. With this design, it appears they have addressed the freezing part by mounting it above the oil filter for warmth and they also are suggesting that the line be cleaned out when servicing the system, thus keeping it clear. I will also be looking at this as the CCV is a pain in the ___. Having just done two of them, I hope they last many years though as it was expensive to do even by myself.

    I used their DISA rebuild kit on both cars, nicely machined parts.

    any amount of buildup can freeze. the condensate is water + oil. water freezes. i had an oil separator freeze that had been cleaned a month prior.

    sure, if it wasn't frozen to begin with. but, say you did a 10min drive and shut 'er down, in the middle of winter - say it's below freezing (you live in illinois, it's entirely possible - and it happens most of the winter where i live). you go out the next morning, and that condensate is frozen - check the link i posted above to see how much condensate can be generated after a 10min drive in sub-freezing temps. it may only be a little bit, but what happens to the frozen chunks on startup?

    personally i have a temperature-activated thermal-switch connnected to a heating element on my catch can/oil separator, and for two winters now that has done the job of keeping things from freezing, no matter what kind of driving conditions the car sees - or if it sits for days on end, which does happen.

    if GAS does not have an answer for the freezing stuff i will likely just add my heating element solution to the GAS CCV.

    So, is this a good solution or would a catch can be a better choice in the long run?
