Hi all, i have read a lot of your post about timing set change out. This noise seems diff as i dont feel anything at my feet. The sound - pecking and increases with rpms is deeper. Louder on the passenger side. car has 132k miles. I have changed the oil. just bought it.

No check engine light or codes on. If its a motor i might try to find a 3.6 with more horsepower. I saw something about diff gm vehicles having more hp. I would be interested in that. Thanks
