E90 330D - Burning Oil

Hi All,

Getting a bit lost now so the car has burned oil since I purchased it, the car will burn around 1 litre per 1000 miles. I've sorted all external leaks (swirl flaps and brake vacuum pump) I replaced the valve cover gasket, had a new turbo which is still in warranty and then I added a loo roll filter as its better at filtering the oil out at the expense of regular maintenance to prevent it blocking. The loo roll filter seemed to have did the trick but it's back to its old ways, I removed the filter to have a look just incase it was blocked and created the crankcase pressure to force the oil past the rings but it don't seem to bad.. Its only been on there for 2 months or so. Oil is still getting past the filter as well I believe as there's still oil in the CCV hose to cold side of turbo.

So am I overlooking anything?
