Which size BMC to fit on Dump valve?
« on: June 28, 2010, 09:09:33 pm »
I know this is a love it or hate it mod, but at least its only a cheap and easily undone at a whim.

Ok so what size diameter crankcase breather will I need to fit on top of the factory dump valve there by converting the recirculating item into a make shift atmopsheric blow off valve.

One other thing will the pipe that comes out of the right-hand side of the engine, which crosses the turbo and manifold just behind the heat shield need pluging/blanking off or is that to stay open? Its quite clear in this video, which has been posted a number of times, how easy and quick the mod is, its just unclear as to what happends with the pipe mentioned above.

    I got mine off the bmc store and it took about 2 week to come.
    i ordered the 30mm one and it was a abit of a loose fit but nothing that a jubilee clamp could not fix.

    have you had any problems with your. A few people had them fitted and there car didnt run right so they took them off. Then hearing disconnecting the battery then the car runs fine with it.

    I can not say i have had any problems. the car has been running great but then i do have the CDA induction system on the car as well. might be something to do with the stanard box but i can not really see that making a difference.
