My Ride: 02' 325i Red
E46 sedan engine bay smoking.

the car:
2002 325i
132,000 mi

so I was driving the car for about an hour around town and noticed that the engine bay was starting to smoke. I opened the hood and white smoke was coming from the back passenger side of the engine. the car also smells like burned plastic when it's off. occasionally I get the yellow oil light when I turn the car off. the cars last oil change was 2,000 ago. it was also recently repaired for an oil leak. anyone know what the heck is going on with this? could it be the vanos?

My Ride: scrapes alot
Well ya got your oil gasket cover repaired? perhaps you forgot about the valve cover gasket. jus recently replaced mine, had the same problems as you. my oil light came up every so often, and leaked.. more then to my likings, if any at all. valve cover gasket isnt a big job, theres plenty of DIY's, about a 30 minute job for me, jus needed to let my car sit to let the sealent dry. 200$ fix, or so.
