Well I am using Rotella T6 5w-40 atm, when i first put it in the noise went away, but after about 1300 miles its back. Goes away tho when its hot, but cold its a slight clanking on that side of the engine..
Now when i say clanking i dont mean like very loud horrible clanking, its sorta just a tapping on that side, doubt its a broken spring, i've felt that before on a Jeep 4.0 and its was pretty bad, this is just a tapping noise no normal person would think about tbh. I've heared of the mystery oil thing, but putting stuff in the crankcase like that i dunno
