Clio 200 Cup
Another thought if things are getting desperate.
Buy some cheap as f**k, much thicker engine oil and put it in. Im not suggesting you run it for long with the wrong oil but if the noise goes quieter/louder (more likely quieter) then you know its an internal problem with a follower or something. If it makes no difference at all then it would suggest a problem wth that cam phaser thingy somebody was talking about earlier in this thread.
