Cold start rattle 2-3 seconds then gone.

Update, just got Blackstone Analysis back. Iron is 22, Copper is 42, and Lead is 83. This is 1,300 miles after getting my rod bearings done with BE bearings in December 2024.

I hate to say it but it is time to get back in there, something is wrong.

Example:
I KNOW for sure (I have the evidence) I had a spun bearing on cylinder #5 (caught it after I had already replaced my bearings and put it all back together. Stupid me...) and my car is still doing fine, no particles in my Oil Filter and sacrificial metals are trending down in my Oil Analysis.

June 20th - 1000 Miles (1600KM) after swapping in new OEM bearings Oil Analysis showed 10 Iron, 19 Lead, and 12 Copper.
July 11 - 1200 Miles (2000KM I have been driving ALOT) Oil Report is is showing 7 Iron, 5 Lead, and 6 Copper.

Very suspicious. I'd probably pull the pan to inspect, sadly.
