Multiple technical service bulletins have been made by Ford over the years in the newer engines. What can cause it is negative travel in the tensioners or just low oil volume in the pan. Earlier mod motors didn't have good drainback to the pan to begin with which was certainly fixed in the current Coyote era. But again, Ford's tensioner design has always been 'good enough' for general production (but not good enough for us). There are fixes for it, namely MMR has spacers that limit negative tensioner travel which requires a lot of disassembly and maybe is not worth it if you can live with the ticking noise. Just don't be bouncing off the rev limiter standing still in a parking lot or something. A loose chain always has the possibility of jumping sprocket teeth and that's one of the most undesirable things.</p></blockquote><p></p>
