Do not go to a higher viscosity oil! It will NOT fix the tick. The bearing clearances on the newer engines are much tighter. You need lower viscosity oil for faster flow. The best way to describe thicker oil and tick is like putting ear plugs in. It’s still happening but U can’t hear it. Additionally you are starving the mains of needed lubrication. Reader beware of some posts on here....
The 5.7's in the 2500's and up call for 5W-30,same exact engine as far as bearing clearances go,the only difference is the 2500 5.7's don't have MDS. The 6.4's are virtually identical in most respects,and they call for 0W-40,also in the big 700 page printed manuals FCA stated 5W-30 was acceptable for the 5.7's in the 1500's if 5w-20 meeting Mopars MS specs wasn't available,this was in the manuals prior to 2017,the 5.7 hasn't changed since then. Also in the big printed manual they state 5W-20 is best for milege,nowhere do they state it's best for engine longevity,you can bet if they thought it was best for engine lomgevity,they'd be mentioning it.Just food for thought for you.
