Hi...not long had this 307 1.6 Diesel estate. Previous owner blew the Turbo and had a new one fitted. There is black oil spilt over the alternator and tensioner, managed to clean this off. Local exhaust centre checked out system and all is well. However there is a constant smell of fumes in the car and especially bad if the blower is put on. It smells as if the fuel is burning rich but having not had a Peugeot before I'm struggling to judge if this is the issue. Can anybody give me an opinion, help would be very much appreciated.
