Engine & timing components had only 65K miles on them. Timing components worked fine prior to tear down. Just had low oil pressure code..which led to the sludge discovery
Timing chain sure but not guides and tensioner. They are wear items, I'd just replace them, just asking to do it again.
Great job on clean-up, VRP 5w30, HPL, Motul X-Clean 5w40, Amsoil SS or even a standard xW40/50 with some Gumout Multisystem Tune Up or Kreen @ 1oz/qt or HPL 40 cleaner ect will clean as well and give you the added visc you are worried about. Even LiquiMoly flush or BG EPR at the end of oci's will do as well
