Default Bad smell in the exhaust Peugeot 407 pétrole.

Hi all, I have a Peugeot 407 petrol with the famous engine EW10J4, the car totals 200000 km, lately I noticed a problem of a bad smell in the exhaust and a slight blue smoke at the strong deceleration, this engine is known for its oil consumption so my consumption is around 1L for 10000 km, I switched to the 10w60 castrol but still the bad smell, about the car works without catalyst, maintenance side all in order, no problems at the injection level, no fault codes just the p0420 (aging catalyst) no power losses, idle stable whatever is cold or hot, no traces of oil at the candles, I want to know where does my problem come from? Are the valve stem seals worn or that's another problem and thank you for your understanding and your cooperation ..
