Had a Blackstone oil report last oil change. Everything was normal wear except lead was a little higher than normal. Just changed the oil and had skim layer of metallic paste on the magnetic drain bolt. Assuming lead. What else is made of lead on the n62 besides crank bearings?

 

Crank bearings are all. The cams run in Al.

Is the car used almost every day or is it sitting for a week and then is run on weekends?
Starts after long periods of sitting can elevate lead.

 

I use it everyday. Looking back at the report, appears aluminum and iron were a bit higher than normal as well.
