[T5ady]

My T5 estate is breathing very heavy.There is a breather pipe on the front of the engine that comes from under the manifold that is temporaly going into a catch tank.This gets full of moisture and oil mixed and when hot you can see a mist coming out of the top of the tank and if you lift the dipstick it also comes out of there.It does not burn oil it does not use water.Before i do compression checks i was going to clear the breathers,how many are there and any more ideas what to check???
