Jeep Grand Cherokee engine knocking noise on right side after lifters, cams, tippets, and valve cover replacement on Jeep Grand Cherokee

Some Jeep Grand Cherokee owners report experiencing engine knocking noises on the right side after replacing lifters, cams, tappets, and valve covers. These knocking sounds may indicate serious engine issues, potentially linked to ignition problems or incorrect timing. Additionally, worn lower engine parts can contribute to these noises. Owners are advised to thoroughly check the lubrication system, including the intake strainer and pump cover, as malfunctions in this area may lead to lifter noise. To pinpoint the source of the knocking, some owners recommend conducting a chassis ear test at a dealership after removing components from the vehicle. Promptly addressing these concerns is crucial for effective diagnosis and resolution of the engine noise.
