I have a 2001 Prelude with an h22a motor.

Only when I accelerate and more so when I am at a low rpm, I hear a faint clicking sound. It seems to do it more when the engine is cold. After driving a while, I don't hear the clicking sound as much. The clicking is very fast, and slightly high pitched. I have noticed that when it clicks white smoke comes from the tail pipe.

I had a similar problem on my 89 Accord, but it wasn't this bad, and I never had it looked at.

Recently I had the exhaust recirculation valve replaced. I noticed the sound was worse after the repair.

Please help. Thank you in advance.
