try cleaning out the small oil filter for the ocv ( inside the cylinder head - small wire mesh behind a plug that you remove with a 5mm or 6mm allen key)

been a while since i removed/cleaned one so not too sure where abouts it is lol.

You can hear the chain? Possibility the chain may have stretched slightly. Not common but have heard of it. This can also effect the engine timing giving a fault code but cant remember which one. Normal things relating to VVTI fault is the controller on the camshaft fails. Also the OCV filter sits just below the OCV. Its a 14 or 17mm headed bolt which houses a gauze filter. But from what you are saying about the noise, it could be something quite serious.
