Strange noise when he is warm?

When the engine is hot, (and it seems to appear when it is realy hot like in traffic, always stop waiting for the green light) there is a strange noise that come from the engine, (a tic-tic-tic, and it goes with the engine rpm) more the engine turn fast, more the noise is stronger and at idle I almost not hear it? It's look like the timing chain but I take a look to it and I don't see what can do this?
First I tought the tensionner was at is maximum and the chain where not enough tighten, but I disassembled the tensionner and it was just at the midle of the adjustement. So I oppen the valve cover to take a look at the chain and I don't see what can be the problem, there is a litle loose between the two sprocket but I suposed it's normal because of the upper chain guide in the valve cover that suppose to make a pression on the chain between the sprocket?
I also look at the valve tickness but there's all in the spec! So I don't think it's that the problem?
It began in the city today so I came back to home by the highway and when I arrive, I did not heard the noise anymore. So it's for that I think it appear when the engine is realy hot!
Do anyone had this problem before?
