Hey friends!
N52 2011
I cut open my oil filter to investigate a really loud lifter tic on cold starts. Bleeding the lifters by keeping rpms up solved my issue.
With that said, I pulled my oil filter after 1000kms, I think what I found is concerning.
• Red circles (Metal): Tiny flakes and slivers. As far as I can tell non magnetic. They are shiny.
• Blue circles (Black crumbs): Hard, but crush into oily crumbs.
• The yellow stuff: I also found some bright yellow particles scattered in the pleats and I have absolutely no clue what they are.
I had the VANOS bolts recall and the VC changed since the last oil changed at bmw.
Should I be worried?
On a scale of 1-10 (1 being completely normal - 10 being foreseeable engine failure) how am I doing?
Please be nice I am new to having a German car I’m hella worried.
Thanks!!!!
