I am new to these forums but I am hoping somebody will be able to advise/guide me with my issues. I have just bought an old 2002 318ci which looks great and drives really well.It has done 109K and with good history up to 97K.
I now have a burning oil smell coming through the air vents after start up and can see that there is smoke coming from the rear of the engine on start up...the rocker cover gasket and oil filter base look clean.
Am i right that this could be the vacuum pump and is it better to replace or to repair. Either way hat kind of cost am i looking at or could the smoke be down to another issue?
Also i have noticed that if left to idle for a while and then gas pedal pressed it throws out a little blue smoke initially then is fine.Only does this after idle and not on start up or whilst driving from what I can see.
Is this related to the burning oil from the car or is it something else?
My thanks for any feedback.
