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?

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.
