Problem with engine oil and engine sound

[Unscaredy]

Hey!


I own a BMW 316i 1.6 17xx cc Automatic from 2002.


Recently I have a problem where I have to refill my engine oil almost every 3-4 days. When looking at the oil dipstick, I saw a very small amount of yellow / white residue at the tip of my oil dipstick. (thought it was a head gasket problem but that was not the case).

My engine also makes a growling noise after several minutes (when the engine is warmed up). This only happens between 2000-3000 rpm when accelerating (SEE VIDEOS with sound)


- Coolant always remained the same (no leaks)
- No trace of engine oil leaks (ground of garage, ..)
- during a trip of 1 hour - no overheat symptoms (temperature always stayed in the middle)
- No fault codes


Someone an idea what caused this ??

Beneath are the links to the videos
