what am i doning worng?

Mines looks brown aswell.

Did you gut your PCV to let it breath? How much oil has it used?

Have you pics of your breather setup?

Empty it out, If its water like, then it will be condensation.
If its thicker like oil, then you may have a problem.

As per the picture, you have the PCV hooked into the line from the inlet manifold to the catch tank?

Try blocking off the inlet manifold, and gutting the PCV to let it breath. Keep the line from the PCV to the catch tank.
I have done this, and my engine is healthy.

i will empty it end of the week, at my garage then.
inlet manifold plug is used for the wastegate and bov

i have hooked the PCV to the carter ventilation plug at the rocker cover(right plug) and together they get to the catch can.

Looks like it is connected up right. Most 4efte set ups have an actual filter on the rocker cover as well, that may be the difference in your set up.

The filter usually goes on where the stock recirculating dump valve was connected onto. Sorry i dont have any good pics.

i now see the confusion.

the pipe to the inlet manifold is connected to the waste gate.

the PCV and rocker cover breather hole are together connected to the catch can witch is breathing after the air filer.

The liquid looks exactly like mine. Water.

Try running a single line from the PCV to the can, and vent the other to the atmosphere.
Obviously for this to work you would have to gut the PCV.

Cant understand why some people run the gasses back into the inlet tract, it contaminating the inlet charge!

Anyway, as stated in the first line, looks like water. 2 min job to find out.

thanks look into this.
i will modify the PCV and let the can breath directly to air, instead of the turbo inlet

Thats the way the stock set up is, I would think it works better having a vaccuum source to pull the oil and gases through, then the oil gets left in the can.

I thought that was the whole point in the catch can without the vaccuum source the vapours won't be effectively extracted, thats always the way I thought of it?

Wallace,

Yep your right, BUT you can also take the other port of the catch can and run a line under the car in the air stream.
Run the line facing away from the air flow and it will create a vacume, and will draw air out, and leave moisture in the tank. Simple but effective.

Its how i have mine setup just now, and the out port line is coloured the same as the inward line from the breather, meaning it works. :p

Thats an interesting way to do it, I suppose the fumes from combustion would go back into the inlet with the way I mentioned but I still think its better than just having one end of the catch can with nothing on it. You see pictures of setups this way and the pipe just off the breather is dirty then the rest is clean (unlike yours) showing that its not doing anything and the can is pointless.

Might give your method a try when I finally get a catch can.;)

Sorry for the post hi-jack sharagath.

Your right in a way, but why put dirty gasses into your inlet stream? ;)
See the pic below to see it does work.

Sharagath, as per the pic, that is how i have my breather system hooked up, bearing in mind, i have the PCV gutted out, so it can breathe as normal.
