Must? when the engine won't run any more.
Seriously, if the engine is making noise, then there are problems, and problems should be fixed. Do you HAVE to fix them, no. keep driving the car and it could "run" for years ( not run well but will move the car).
Sure you can wait and drive the engine until it stops but if you are looking for an absolute drop dead measurement there is none.
