i switched to mobil 1 1030 synthetic about 15k ago..i use to run castro gtx..i mentioned a clicking noise coming from the cam gears side of the head a while ago..btw i have a moon cut cover..im told now that the clicking noise is probably because i need to use a different oil? maybe 530 instead or go back to dino oil.
im pretty sure i dont need an adjustment..it was done 3 weeks ago by a shop nearby..i know what it sounds like when i need a valve adjustment..more of a knocking noise..but this is like a clicking noise from the cam gears area coming from the head..
