Need opinion on timing chain job
Have a 2007 with 186,000 miles and it has made the whining sound for a year, since I bought it. Video of engine sound:

I need your opinion. Do I get the timing chain, guides, and tensioners replaced? Or do I risk it and drive it till it dies due to age? It will cost me between $2k and $3.5k depending were I go because this is beyond my skill.
Recently I had to replace the crankshaft position sensor. It has some rust, but not as bad as others I've looked at. Not sure on past history, but looks like the following were done in recent years:
Catalytic converter and O2 sensor
Camshaft position sensor
Ignition coil
Serpentine belt
Brakes
Battery
Window regulator
What do I do?
