engine bay
hello guys
well the problem began after i replaced my eccentric shaft sensor and servomotor beneath the valve cover, also replaced the gasket. The next morning I turned on the ignition and while waiting a little bit for engine to heat up I realised that there is a light white smoke or vapor, when checked the engine bay realized that it is coming from beneath the pollen filter panel the strange thing is that it stops after 2 minutes. I also realized after a week that my oil level has dropped. what do you think guys ?? |

White smoke usually means coolant is burning so or if you have a tint of blue then your burning oil . You def have a leak, try running some compression tests or a leak test.

If you pull your dipstick our and check to see if you see any signs of coolant mix or if your oil looks like choclate milk.
What you might also want to do is try washing your engine bay to get rid of any grease or oils that might of spilled anywhere or came into contact with your block/head anywhere since you did some recent work to it.

I think the source of the smoke is from the vacuum pump as it is coming from the back of the engine and also oil collecting on the heat shield above the exhaust
do you know if this is one of the vacuum pump symptoms ? |

It took me too long to figure until i had my o2 sensors replaced it turned out to be that they are loose and not well torqued.
