That could be a failed lifter or a failed timing chain tensioner causing pinging or knocking. With the mileage you have a failed wrist pin on a connecting rod is possible.
A failed fuel injector can make a loud ticking noise
Take a screw driver and put it to defferent areas on motor, i.E; near top end to see if you have a noisy lifter or near fuel injector to see if one is loudly ticking.
Let me know how it goes.
