For every two revolutions of the crankshaft, the cam shaft revolves ones and a sticking valve or lifter will tickk once. A bad chain can make a buzzy sound that relates to the number of sprocket teeth. So valve tick is slow, chain noise is fast and buzzy.
That is the mechanics. Perhaps others can clarify chain noise. I have only heard a mild valve tick on this engine.
Low oil pressure can reduce tensioner pressure to some extent. There is a pressure relief valve that can stick open. Simple spring loaded piston job. On timing cover, facing down, front corner. Bit hex, remove that, sealing washer and spring. Get piston out. If it comes out real easy, then there is probably no problem. If it does not want to come out, not so easy to get out. Inspect piston for scores etc and smooth off any damage. Does happen, but not often. Easy to check.
