640I F13 engine noise at stop

[hart07]

Hello everybody , i noticed an engine noise when the car is runing but at stop, i hear a kind of noise like belt or timing chain ( i don't know ) something is hangs .

My car is from 08/2012 and 99400 miles.

i did the classic services ( oil change, filters air and AC) need to bleed the brake now, but what i missed ?

i need to bleed the automatic gearbox drain , but my gearbox is ok and is not the problem.
its like a noise belt or timing chain perhaps .
the drive belt ?
Thanks for your help.
regards

you are better of posting in the f30 forum in the n55 engine section. more knowledgeable people will be able to help diagnose the problem. people here usually take there cars to the dealer if anything arises

also it seems your oil filter gasket is leaking. i would recommend getting that repaired asap to prevent future damage

You really think my oil filter gasket is leaking?
Why is possible
I will look better this one but sure there are some oil on the right side, perhaps old oil.

oil filter housing gasket is leaking on my car or its perhaps a housing filter with too much torque when i changed my oil in june 2019.
i changed my oil filter and drain my oil in june 2019.
perhaps i torque too much my oil filter housing and result this leak ?
or its a classic issues with this oil filter housing gasket ?

how many miles are on this car> oil filter housing gasket will eventually leak from the inside.

only way it leaking from when you did the oil change would be if you didnt actually torque it down all the way.

if still have an other issues. again make a post here for expert adivice

I think it may be one of your pulleys and/or belt. My oil filter housing gasket was leaking (common occurrence with this engine) and oil leaked on my belts and pulley. Had the oil filter housing gasket changed, plus belts and pulley.

Edit: IIRC they replaced a pulley, belt tensioner and belts due to my oil filter housing gasket leaking onto them. From your video, it looks like oil housing gasket is leaking as well.
