Ok so let's begin.

1'st of all you need to drill out the original rivets that hold the baffle plates in place using a 7mm drill.

Than....you will discover how much junk that baffle plates are hiding....and all of which is going into your engine

After the drilling of the rivets use a heat gun to ''moisten'' the black silicone.
Than gently .,...with a flat screwdriver take out the baffle plates....if needed slighlty enlarge the holes which you previously did.
After that use a hand drill with a tool like this one to completly remove the silicone

After that you need to find a right place for your new breathers...I have choosen this spots and used a 16 mm drill to make the holes.
After drilling I have found 2 pieces of 90 deg from some old air con lines.

Definitive Breather setup - Page 2 20140516_122422_zpsf8e31423

After that I have welded them in place

I don't have pictures ....but I will upload some tommorow (on putting back the baffle plates).
I will be using some 4mm screws......
Where the rivets were.....drill and tap to suit a 4mm screw (or whatever you like) but ensure that you don't drill too much....so that you wil perforate the other side of the rocker cover.


P.s. I will also make an catch can.....which migh be available at request:D:D:D:D:D
Enjoy

Ahhhhhh....
I forgot...the extra breathers are 16mm in diam....because the original is 16mm....and I thought that's the best way of doing it!

Ok....so now for the final step.

I have used this......you can use whatever you like Smile)
I have drilled a 3 mm hole and than used an 4x0.7 to tap it.
Definitive Breather setup - Page 2 20140517_111317_zps3672ce5e
Than....just screw back the baffle plates....et voila.....baffle splates back in place!

Definitive Breather setup - Page 2 20140517_123130_zpsb46e7366


Just for your info ....on the back of the baffle plates....there's only one small and flimsy mesh type screen and that's about it.....and oh....the rocker cover without the baffle plates looks like a maze....and that's the reason why it stop the oil from comming out the breathers

Johnny I did the same with my forge. It used to very quickly emulsify in there, so I moved in from the slam panel to the n/s inner wing as I thought the cold air blowing onto it was making the situation worse. I then blocked off the drain outlet. Much better since doing that, only downside is having to regularly drain it.

Just to drag up another old topic Laughing

What's the purpose of the restrictor from the standard separator?

My car has none of the plenum pipework and the pcv outlet was bunged, seemed to be fine when it had the gti rocker cover on but now that I have changed to a gtir the breather was spitting a lot of oil from it.

Have stolen the pcv from my other engine and knocked the inside out, just venting to atmosphere, car seemed happier but that will just be a placebo on my part, we will see if it stops spitting oil.

Before anyone mentions excessive blow by/rings etc, had a leak down test today and all is good.

Here my temporary setup, need some longer hose and something to catch it in.

I just read through these topics and its really interesting. Gives you a heap of info on how the breather ventilation system works on NA and turbos and also the difference between SR models. Really helped me understand how this works

Just to drag up an old thread, I am trying to sort my breather system out as I dont have the carbon canister and there was a pipe missing on the PCV pipework so it was running like a sack of poop on tick over.

Now I have removed all the PVC pipework and blocked the PVC valve off using a bolt to see if it helped idle and it has helped greatly.

Now this is my setup.

PVC piping all removed and blocked.
Nipples blocked off.
Right hand top side of block - T goes to catch can (vents to atmosphere)
restricter pipe to oil separator still in as normal

So basically I have done away with the PVC and instead of the pipe going back to the induction it just goes to a catch can.

Now ideally I don't want to be blocking off the PVC valve right? so I need to punch it through and ideally run that to my catch can along with the other pipe and then either vent to atmosphere (not ideal) or a better method to then link the oil catch can back to the inlet pipe of the turbo.

Just a question, why did people sell the PVC blanking kit then? I know lots and lots brought the kit so why was it acceptable then and now its come to light that its not a good idea to have less breathing.

Lile this..

The red represents the pipe from the old pvc outlet on rocker to the catch can then from the catch can to the intake pipe!
