Nissan TITAN motor making loud ticking sound after short block installation on Nissan TITAN

Some Nissan TITAN owners report experiencing a loud ticking sound after a short block installation, which may be attributed to various factors. One common cause is the use of a cheap oil filter lacking an anti-flow back valve, resulting in a ticking noise that lasts for only 1-2 seconds until oil reaches the valve train. Additionally, some owners note that a failing differential can produce similar ticking or clunking noises. Furthermore, there is a Technical Service Bulletin (TSB) addressing engine knocking in certain cases, which may necessitate replacing the short block or long block if the noise intensifies. It is crucial for owners to have their vehicle inspected by a qualified mechanic to accurately diagnose the issue and recommend appropriate repairs.
