For anybody that are 16V afficianado, my question is my motor is pretty quiet when its cold and when the oil temperature goes up the valves started being noisy. I look at the tensioner it the updated one and the timing chain seems to be new. I guess I have to find out when it was replaced. But I did a valve adjustment via shims since the valvetrain is not hydraulic. Also, when I accelerate and let of the gas i hear valve noise i don't know if its the chain or the valves. any suggestion would help. I ran thicker oil to and thinner oil, its still the same noise.

thanks,
Ernest
