I am looking at a 2008 pontiac torrent. Runs good, no engine lights are on. we started it, fired up fine. My husband opened the hood and said it has a ticking noise. I could barely hear it myself. You cant hear it when the hood is closed. It does not get louder when you accelerate. It is the GXP model with i believe a 3.6L V6 SFI. Do these engines just have a quiet tick to them? I have read they do, so i was wondering if this is bad or not. Like i said, once the hood is closed you cant hear anything and does not get worse when accelerating. Thanks!
