Apologise if this question has been asked before, I had a quick scan through several pages but couldn't find anything ( I think I know, in my heart what the answer is ).
I drive a 05 plate Astra SRI Turbo (170), only done 38,000 miles.
I drove back from work last night (18 miles) and parked my car up for around 2 hours then drove around 2 miles then, when I got out the car, engine still on, I notice rather a lot of smoke coming from the exhaust (the smoke was white / blue with no smell to it), I know it was a cold night but I don't think it was condensation! I left it over night then I started it this morning, no smoke, but then after a couple of hundred yards I stopped to see if the smoke would reappear... it did. Anyway I got a mate to follow me whilst I drove the car hardish down the duel carriageway... the smoke stopped. Put started again when I was idling. Obviously oil is getting into the exhaust, probably through the turbo, but I wonder if it could be anything else? as I've had no noises coming from the engine bay to confirm if it is the turbo? Any advice would be most welcome.
