Thought I'd share this UOA for my Hemi with rising copper levels. Iron is low so I'm not worried about the dreaded cam/lifters but apparently there's a bushing that is wearing excessively. Any thoughts you have are appreciated. I don't really notice any weird noises other than an occasional irregular tick now and then.
The truck is a daily driver that tows about half its max load about once a month on average. Some idling, but nothing like sitting in traffic in a city every day.
Last year someone said I'd see an oil pressure drop at idle or at higher RPM if bushing wear was an issue. Haven't seen that condition pop up when I occasionally check it while driving or when it's idling. Always around 30-35 psi at idle and 50+ when RPM is >1000.
