Oil and results

I added 1 qt of Mobil 1 High Mileage 10-40 (M1HM1040) and the noise subsided to almost nothing. I am thinking cam-chain. Does anyone know where I can find info on GM V-8 5.3 cam-chain.?

Been on since 2001.

Boycotting Castrol for calling their Type III Syntec oil "Synthetic"; Boycotting Mobil1 for changing most of their bases to Type III and refusing to admit. Royal Purple identifies PAO/Type IV as their base; Red Line IDs Group V/ester as base. G80=Gov-Lock=>Locker,auto (not Limited-Slip)
