To replace timing chain;

Parts $197.49
Labor hours 4.30
Labor Rate $100.00/Hour
Total Labor $430.00
Misc. diposal and supplies charge $45.00

Total $672.49

This is based on repairs at a high end shop or dealer in a sububan city. If you go to an independant repair shop labor rates may be cheaper. If you live in a rural area the overall cost may be less.

Loud clicking noise probable causes could be the valve lifters depends where the noise is emitting- oil pressure problem-also have the computer scanned for code/s
