Mine seems to tick a bit , seems to run out fine but ticks at idle. to me it sounds as if it may be valves(?).

any thoughts?

thanks

Could be the valves, but if it is a faint tick, it may just be the fuel injectors pulsing.

Yes -- and there is a TSB out to fix it prior to VIN 30124293. I'm assuming it's an '03. The TSB is 02-06-02-037 (Excessive Engine Noise).

I have an '04 3.2L and it has a mild ticking sound at idle. I can't imagine what it sounds like without acoustic covers that are recommended in the TSB above. While mild, it is still clearly noticeable. However, my understanding is that it's completely normal.

So in otherwords all I need to do is call my local delership and have an appointment made to fix this on my CTS?

Just do an cly firing test if you don't have a reader go to auto zone where you use one for free . Check the O2 levels and kvs(firing voltage pirmary and secondary) in the cly that will give you a good idea where to start from sticky valves or bad cam lobe
