Renault Clio 2 1.2 16V oil in air filter and emergency run

Hey guys, I already asked a question about oil in the plug from the throttle valve Poti and the resulting emergency run a few months ago. Now it is that after less than 5,000 km the engine has gone back into the emergency run. So disassembled and see again everything full of oil. So I cleaned it and error is gone first. Accordingly, oil is burned of course. On request at Renault they could not help me any further and also I am with my Latin on the End. Does any of you have any idea what else I can do? Starting engine damage? Fzg is a Renault Clio 2 Phase B 1.2 16V D4F-712 Thanks already in advance.
