Do'h

Just been for a run and heard a rattling noise coming from the airbox side, also noticed oil burning through the exhaust only intermitently and only at standstill after a few moments at idle.
Checked the air intake and found oil dripping out of the filter?
Is this turbo problems or rings gone or too much pressure in the sump pushing up through the breather into the air intake?

Questions, questions, questions.

Thanks a lot.
