Ram 1500 engine knocking sound issue related to lifter replacement on Ram 1500

Some Ram 1500 owners report experiencing engine knocking sounds related to lifter replacement, often attributing the issue to lifter failure that results in ticking and knocking noises. Instances of loud lifter noise have been noted, with some new lifters failing shortly after replacement, potentially due to underlying cylinder head issues. While replacing lifters can significantly reduce engine noise and delay future lifter problems, some owners suggest using thicker oil, such as 5W30, to help mitigate engine noise, although lifter failure may not be entirely preventable. Additionally, engine knocking can stem from other causes, including low oil levels, ignition issues, timing problems, rod bearings, or malfunctioning knock sensors. Regular maintenance and prompt attention to unusual sounds are crucial for preventing further engine damage.
