I have just started to work on the engine on my series 3 diesel.
It is smoking baby blue smoke only on hard acceleration,so i changed the fuel filter and no change but did smell a really weird smell from it it smelt like paraffin and white spirit
So i drained the tank and got a strange coloured liquid out of the tank,it had red diesel in it but was more of a orangey colour.
My question is what sort of damage could this have done to the engine?
I have heard that these engines are very hard wearing but am worried about the damage that could have been done i have no idea how long the engine has been run on the fuel as it came from a farm.
I put some clean diesel in from a garage and the smoke has become less but im still worried any advice would be great.
