I changed the cam and lifters and have put 38,000 miles on it since then. Put the Crane cam made for the LS1 in it and crane lifters as well. I guess I may ask is the Valvoline ok in the engine or should I switch to an oil W/O sodium?
It is more of an anecdotal observation but it does seem to pop up more often than not when looking at issues like soft cams and exclusive use of Sodium add pack oils in place of Moly based oils.
As for advise on changing oils, I think you have already replaced the weak link with that being the cam and would be fine continuing with Valvoline.
Thanks Hootbro, I have always used Valvoline in all my vehicles except my Subaru. I have read others having cam issues, Valvoline is Dexos 1 and sure it's not the oils fault.
