Hello everyone, new tbss owner here from the Bay Area, Ca. I've owned several cars in my time and felt like it was time to let my current one go and get an Ls powered car. So I decided to go with a trailblazer. Picked up a 08 with a small ticking/knocking sound. So now I'm here to get a bit of help. I'll start up a thread under the general discussion or proper area with more details and videos.
