Dear Forum members
I am a new member and wish to request advice about my newly bought second hand car-the above Ford Focus. I am not very knowledgeable about cars by the way.

In a nutshell there is a smoke problem. When I start up and rev the engine, it is sometimes has a lot of bluish smoke. Other times, although there is some smoke, it isnt as bad.

I have only driven it a bit so far, but from the drivers seat looking through the mirror the smoke doesnt seem too bad, although I understand one has to be behind the car to see properly the smoke. furthermore I havent driven it fast yet eg on the motorway

Other than this the car is a lovely smooth drive, and there is no rough feel to the engine. It seems to me a novice quite lively.

Please can anyone advise what might be the fault with the car. Is the engine just worn, or is some other part faulty. Would it be possible to get a diagnosis. is there any chance the car can be fixed. It wasnt a very expensive car. Any help or advice would be most welcome.
Yours sincerely
Ian
