I suspect timing chain problem.

Hi everyone I got question about timing chain! How you can tell if chain is bad? When I start car is very loud rattle noise and then after 3 seconds it's run normally... How you think its can be chain problem??? Thanks for the help

Or just chain tensioner issue , that's how it primarily starts , ignored it then turns also into a timing chain issue .
