On mine, see my pics on other thread,
I have breath holes on each side of the block, these go into the top of the breather
at the bottom I have one hle, this is return to sump (Below oil level)
the third at the top is vent to atmosphere, on mine this goes to the catch tank which then vents to atmos below car

just finding my feet
they look shiney though
dont breathers also hide potential engine problems briefly,,,,,,,,,,, as in stop the filler cap poping off for a while until the piston craks get worse
just asking as ive seens a few cvh's with this and that solved it until the rings/pistons gave up totally and just assunmed that
oh and there shiney too [/code]

Please explain ??
Why do you say this kit is no good , i have used it on every cossie i have ever owned and they have worked perfect for me ,,even on my track car this system has been 100%
It works in exactly the same way as the G/Goode system exept i fit the tank on the left and extend the pipes

im going to do:
top 2 , one from each rocker cover (driverside comes direct from cover, passengerside goes via 1 way valve)
big bottom, atmos (erm sorry, i mean a catch bottle, honest guv)
little bottom, return to sump

ps can i ditch the 1 way valve (i'm guessing its to stop an air leak in the plenum (which will now be blocked off) rather than to do anything oily

Sounds ok if the crankcase isnt easily accessible, i dont have enough direct 24v experience to comment sadly.
The valve is there so the crankcase is vented under light throttle conditions, as long as you bin it and adjust the mapping to suit you will be just fine. The main issue is the plenum fuelling is calibrated to cater for this controlled intake leak, so be prepared for it.
IMO its best removed from the intake system totally unless you can guarantee the intake some clean, oil free air, and that is VERY hard to achieve.

thats what i want to do, block it off plenum end (no in to plenum) i mean can i take the 1 way valve between my cam cover and breather (i assume yes after what you just said)
then i'll end up with no breathers going anywhere near the intake system anywhere

fit one that breathes from both the normal postion and the other side of the block..
mines(bailey) breathes thru the cam cover and seems to work perectly s i use no oil and oil get water vapour out of the tube to the ground, but if you check out most of the "properly" built big power cars eg the old touring cars they all seem to have the both side of the bolock set up.

Stu, what is your opinion of my setup?
Bailey separator, breathing from top of the std flame trap, and from the plug on the turbo side of the block. Return is via a welded on nipple below the oil level on the sump (think it's -8)
Cheers!
Neil.

I will elaborate so you understand, using the pictures above as my example:
Basic rundown for a breather system to be more efficient than a std one:
The Standard system comprises of one kidney box oil vapour separator that alleviates the crankcase pressure via 1 x 15mm outlet, venting to atmosphere via the standard air box.
Biggest problems with the std system:
1) It is only 15mm, not ideal for cars with large blowby.
2) It draws fumes and oil vapour, as standard, into the inlet under all off boost conditions, via the one way valve often causing oil burning.
3) It is only plumbed into the nearside of the block. Under hard right hand corners, oil surge can see the oil totally overloading the standard system and sending neat oil into the breather, often seen as oil pouring out of the oil filter.
Problems with the system in teh picture as they "Appear":
Point 1) Unless I am missing something thats hidden, is not addressed at all?
Point 2) This is "possibly" addressed? (Cant see inlet clearly)
Point 3) This is almost certainly addressed but im not sure that the O/S hasnt been used as an oil return instead? If so, it can only return oil when off the power unless a special adaptor has been used to drop the oil below sump lubricant level?
Hope this helps....

Good mini-essay
Neil.
basically, we could have, for example..
2x 15mm from cam cover.
&
2x 15mm from crankcase.
If we only have 15mm to vent all this out of, we are still no better than it was as standard IMO. Other than teh fact that you may have 15mm from both sides which solves the crankcase oil surge issue somewhat.

the pipes that come with the bailey breather are quite big maybe 22 mm?
mines vents from normal place and cam cover and has an oil return into sump and large pipe that exits under the car...
surly the bailey set up must work or why would he have sold so many??

mines standard at the minute, looks like i'll probably keep it that way. just give it a good clean.

I keep meaning to put the vent pipe into a container to see if any oil comes out, but I haven't got round to it yet...
Euan - I think that people are like sheep - they buy what they're told to without considering the problem for themselves
Strut braces held on with self-tappers anyone? Neil.

i have put my breather into a bottle and only get small drops of water...
take it that means its working?
the breather system is somethig that has never been fully discussed on here IMO
could some of the tuners etc put up their views on good, bad or ok systems and what to look out for if yuor breather isnt working propery?

I dont want to get involved in why people buy XYZ products, as i dont like to get involved in any scandalous accusations, but lets just say Shiny sells... The CVH swirl pot is a fooking cracking example of lunatic uninformed purchasing!! 
Anyone reading my reasoning behind the breather system should be able to see what will, and conversely, will not, upgrade their system.

Whilst i can see what your saying, i feel that the concept of 30mm input area requires 30mm output area is very simple and thus its very easy to see with the untrained eye that LOTS of systems dont cater for this most basic of requirements.
