It's been ~8K miles since my timing chain tensioner and all associated bits were replaced after having a failure around somewhere around 70K (repaired at ~83.5K and now at ~92K). I'll link the post here:
This is the second oil change since then so expect to see iron/aluminum values continue to drop off when I get the UOA back.
Still seeing a few bits in there but could just be remnants of the timing chain tensioner failure....unfortunately I didn't cut the last filter open (forgot). I've never seen any of the "carbonaceous crud" that some have posted after using HPL...I've had HPL in there for over a year and have used the EC as well as LM engine flush many times previously....so I doubt there is really anything to clean out.
Aluminum flecks in oil filter
Cut open my Mann oil filter for my Sportwagen today after changing the oil at about dead-on 5K miles/3 mos. Last UOA showed increased aluminum numbers, it was a mid-OCI UOA after a trip down to GA for a VW event where it was used hard on the roads with "dragon" in the name. Quite shocked to see...
