I am running 10w30 Mobil 5000. Should i switch to a heavier oil to see if it clears things up??
Are the rockers new, or did you reuse the old ones?
Stock stamped MoPar rockers have a tendency to punch through when you use a higher lift cam- I always use adjustables with faster rate of rise cams.
I doubt the oil will make a difference- ifit is rattling with 10w30, it should still rattle with 10w40. The first number is its viscosity with the oil at operating temp
