Cordial companions greeting ,,, I have a 2002 symbol, the fact is that when changing the engine air filter, I found that there was oil. In some internet consultations, they suggest that I check the positive ventilation valve of the crankcase, but the inconvenience is that I cannot locate it, some cars have it near the valve cover, but in the Renault Symbol I do not know where it will be ,,,, I would appreciate who can help me with this.
