Hello everyone . I am not a Ram owner yet and that is why I am here. To research the Ticking noise caused by faukty lifters that lead to worn cam shaft lobes. wondering if the issues is isolated or common and if its been addressed for 2020 and 2021 6.4 gas engines.

lifter issue fixed or not?
Doing some research on the HEMI 5.7 and seems the lifter had serious issues which destroys the camshaft - see video here: Is this issue isolated to some older model year or does it still exist on current models?

One thing you may want to look at, is the quality of fuel being used. Fuels that contain high amounts of ethanol or that are low-octane may not properly lubricate the fuel injectors and can lead to a slight tapping or ticking noise. Low-octane gas has also been known to cause an ignition knock in high-performance engines. Using fuel additives or a high quality gasoline can help prevent this from occurring and may be able to correct or minimize a HEMI tick.
Lubrication is very important in a HEMI.
