Fair amount of Oil in Intake system

I redid some of the awful plumbing from the intercooler to the turbo and at the same time replaced the air filter...I noticed a nice coating of oil in all of the pipes and in the intake...I assume most is coming from the oil breather cap hose to the air filter housing...firstly what is the purpose of that hose from the breather to the air filter...is it just reduce any pressure? Can it be removed if I bypass the whole air filter assembly and just use a reusable air cone attached a short way from the turbo inlet?

Surprisingly once I redid some of the plumbing that had a hard right hand 90 in it just after the turbo and a squashed 90 into the intake...both now have a silicone soft 90 hose...I also ensured everything is nice and tight and new paper air filter (old dirty K&N prior which will be cleaned), I lost 2 psi of boost.....but the engine actually felt much more responsive...

That whole oil breather to the intake thing is to keep the oil off the ground. It's for the children, beagles and the bald eagles. If you hate children, beagles and bald eagles you could run a hose down towards the ground or you could install an oil catch if your zen will take a hit. Once you do that any air cleaner could be used.

While I don't hate beagles, I prefer my Springer Spaniels...kids, well I prefer my Springers...lol..What if I just plugged the hole from the oil fill cap?...what is the actual function...release top end pressure?

You will pop the cap off and kill a child, beagle or eagle. It needs to vent somewhere. Run the hose to a catch can and empty it from time to time.

Having to clean the oily residue off intakes isn't uncommon in VW tdi's. So just get in there and clean it up

Yep, been there. Oven cleaner, a wire bristle brush and some hot water. An afternoon of fun...

The rubber donut on top of the valve cover that the oil fill cap fits into is missing and oil is constantly dripping from there...once I get the donut then a good steam and green engine cleaning for everything...oil is everywhere...and can't tell if I have other leaks until thats done!

Are you consuming a lot of oil? If not, then don't worry about it. Nothing wrong with oil in the intake. If you are, then add a PCV oil cyclone if you don't have a stock one.
