From you photos your rocker breather is connected to the intake. This is fine. Usually air enters the engine via the rocker cover, but you can get flow the other way. And you can get oil in your intake. How is the rest of the PCV system run? Being a boosted setup the PCV valve may have been removed and this will promote more flow to your intake. You need to find out how the rest of the PCV sytem is setup.

PCV syytem is setup stock..

Yup I need to stop the air going backwards.. how?

Not 100% correct. The tube going from the intake arm to the head is a "intake" for the PCV system. This means its generally one-way. So if everything is fine there should be no oil in the intake arm.
Luke needs to replace his PCV with either a new PCV , or look at a upgraded system that works to keep most oil vapour out of the intake manifold.

PS DL001 , Luke's PCV system is run the same as a stock car. This maybe the key to why he is getting blowback into the intake arm

where is the oil in the pipes?
between throttle body and intercooler?
intercooler and turbo?
or pod filter and turbo?

Ok, so how is the system run on this motor?

Confirm where the oil is? Intercooler piping or the turbo intake?

I only saw the hose thats running from the rocker cover to near the turbo.

But noticed now theres a tube from the intake arm to the head?

Yep, agree, tube from intake arm to head goes in the motor and then the one from the rocker cover goes out to near the filter? Confirm?

Wheres the valve?

At this stage all I can see is boost in the intercooler piping entering the tube to the head. Thats not good. :confused:

Na its setup correctly as per GReddy's setup guidelines

But if its illegal how can I fix this?

just run the hose out of site and attached a breather to it... thats what i did

or put a breather at the end of the hose and put it next to ur pod filter and build one box to enclose it all

Even if this happens, it means air flows from the intercooler piping into the valve cover and not the other way around when under boost because the pressure in the piping is above the pressure of the valve cover.

Cool

So where do you get this little breather filters from anyway?

SuperCheap?

And would this not then push air through the engine and out from rocker cover to intake to turbo? This will then explain his oil in the intake to turbo. Sorry don't know how the system works on these motors.
