Hello I added a quart of oil to my 2004 BMW 325xi while it

Once the oil ran down into the engine did the noise and smoke go away?

Where was the smoke coming from?

It did go away. I don't know where it came from.

Did you spill oil on the exhaust? If the engine is running smooth and there is no smoke your engine probably is OK.

I didn't spill any. It went away after I shut it off and started up later.

Maybe a bunch of oil got sucked up the PCV.

Un-metered air coming into the engine from an open oil filler cap will sometimes make them run rough. Do not add oil with the engine running.
