Hello Boys n Girls,
after browsing through posts in the R53 section for weeks trying to find a solution for my problem i thought i´d now create a post to ask some help from you guys.
After having owned a R53 S (which i gave to my mother) and a R56 Works ( which sadly blew up) , i was browsing the web for another R53 S in good condition as these are getting rare and also slowly goin up in price. ended up finding myself an 2006 R53 S Park Lane with around 100k kms on the clock. First owner, full paperwork, lots of replacements, really good condition, blah.
After buying the car i somewhen noticed some rattle at idle . apparently coming from the left side of the engine, as far as i can hear. its not constantly there, coming and going. sometimes louder, sometimes not. it rises when the engine is revved up.
what i did so far but didnt help:
Thought about rod knock but i checked the old oil filter and there was nothing to find. when my r56 blew up, i found metal shavings in the oil filter and it made quite a diffent sound compared to the sound that can be heard in the video.
i did not have the oil pan off so far bc the car is now standing in a garage at my parents house which is not around the corner.
When the engine runs without aux belt, the rattle is gone ,even when revved up....
with the good old screwdriver method, the sound can be heard very clear on the housing of the alternator. i checked the alternator when the charger was off, bearings seemed to be fine when i turned it by hand...
so i´m a bit lost. it also doesnt sound like a chain rattle to me.
i think i might notice a lack of mid range power compared to my mums R53. oil pressure shown at the chrono pack - which they both have - also seems to be lower than on the other Mini. when changing the oil, i found two small tiny black pieces, barely noticeable on a fingertip, when in checked the oil after draining. with a lighter flame, they melted straight away, so this might be plastic? at idle it seems to run a bit "rougher" than normall, respectively i got the feeling that the car vibrates a bit more at idle than it should.
heres the video link:
maybe someone experienced similar noises or has a good idea to point me into the right direction. bit of a bugger now but i like that mini and its condition so it would be sad to let it go.
appreciate any help, thanks in advance

what i did so far but didnt help:
- replaced idler pulley
- took supercharger off for service and WP change (which both were in very good conditon)
- took cam cover off to check condition of chain, sprocket and guides (didnt see anything faulty apart from the fact that the chain had a bit of slack on the non - tensioner side when i lifted it with my fingers. had the cover off one more time after that and this time i could not lift the chain with my fingers, no slack at all )
- replaced chain tensioner (which also was good)
- changed Oil and filter, plugs, air filter
