Vauxhall corsa engine

hussei3232

Hi 
I don’t know much about cars but recently I had to get my engine replaced due to a big cloud of white smoke coming out the engine. This is my fault as I hadn’t changed the oil since buying the car (2 years ago) and apparently the engine was fully dead. 

So I’ve just got my car back with a new engine however my car is still smoking from the exhaust sometimes when I am driving or I stop the car and drive off. The mechanic says once I drive it a little more the smoke will clear up from the exhaust. I have no idea what he means by this and is it okay to drive it’s really giving me anxiety. The smoke isn’t a lot but it’s still enough to worry me and make me think it isn’t right.

When your engine went bang because you never bothered to check the oil level it threw some into the exhaust along with whatever else happened to be in the engine at the time it went pop for the sake of not checking the oil level and putting £5 worth of engine oil in. This will take time to burn off.

If you don't check the oil level regularly then this engine may go bang too for the want of a few quid worth of engine oil. You should check it at least once a month, not just wait until the next service is due.

thank you for your response. I will check it regularly now. So can I still drive it and how long will it take to burn off?

When you say new engine you realise you are very unlikely to have a new engine. They are very expensive so you normally get a second hand one that the mechanic has managed to find. They are a bit of an unknown quantity normally. Say you have a newish car and somebody runs into the back of it and writes the car off. That engine would probably be perfect. Say someone has an oldish car with a smoking engine. They may decide to scrap it. The scrapyard may then sell it's engine saying as far as they know it is OK. Do you know where your engine came from? He may be right and the smoke will go away or you may still have a problem. He won't want to replace it again as he would have to buy another engine and spend time replacing it.

Check the oil every morning, before you start the car. If the level is going down, then take it back as something is wrong. If the level stays constant for 1000miles then you have a good engine.

It depends. If you go on long journeys, and the exhaust gets properly hot, it'll be a lot quicker than if you only ever do short pootles.

Yh. The thing he has the receipt for it and it has 6 month warranty. So what he was saying was just drive the car and the smoke should clear up soon. And if there is any engine issues he will refund me my money as he can return the engine to wherever he bought it from

It roughly translates as "I don't want to spend any more time working on this car.  Now pay me and go away."

Depends on how bad it is smoking. If all you can see in your rear view mirror is smoke then don’t drive it let it run on your drive

Do you honestly believe that would ever happen? Who would pay your mechanic for the removal and return of the engine. And the installation of yet another engine?

Why not take it for an MOT? That would soon determine whether the emissions were acceptable.
