Just change the oil. Keep the oil filter in place and change the oil. I did that a few times and my lifter symphony went away. I have come to the conclusion that it is the newer oils breaking down in our Hemi motors sooner than anyone wants to admit.Have a 2021 Ram Truck with 985 miles.
lifters are clacking away!!
Dealer told me it’s common.
Have to wait for complete failure??
Last RAM truck.
Stick with my old MOPARS made here with USA METAL!!!
340/383/426/440 BEST MOPAR MOTORS EVER!! OK I will throw in the weak 318
I used PUP 5W20 as recommended and sometimes the lifter singing would start before 2000 miles were put on the oil change. PUP 5W30 would go a little longer, but would never reach 3000 miles on the oil change. Listening to the people on this forum, I have done 50:50 mix of PUP 5W30 and Red Line 5W30 or QSUD 5W30 and Red Line 5W30 and either a Royal Purple or Mobil 1 oil filter. I change the oil between 2500 and 3000 miles and leave the filter on for 5000-6000 miles. Never a chirp since using this stragagy, even when the truck sits for a week or two.
The reason I do the shorter OCI is because of the grit and contaminants that accumulate in the oil. The oil may be able to go farther, but it is still loading up with contaminants whether it is synthetic or not. There are too many tight clearances in the Hemi from the bearings in the lifters and the screens in the MDS solenoids. I believe any contaminant that is large enough to slip through a cheaper filter may get caught in these tighter tolerances and help with the lifter/cam siezure.
Bought with 16,000 miles and now have 36,000 quiet miles.
