Well I left it running last night for a hour and it started it idle less lumpy so went for a drive to get some temp in to it and guess what the smoke has stopped and it drives well power is good too
so changed the oil and left it over night,popped down this morning and started the car and the smoke was back but not as bad
Drove the car 15 miles and no smoke?
but the old owner has told me that it has smoked for a few minutes before it went in the water

Could it be an injecter problem ?but no engine management light on and no smoke after 2 minutes of running
Think i'll get it compression tested first

What do you all think
