Went yesterday and spent almost 2 hours between driving around with the tech to hear the rattling and then him finding the problem. Ended up being our CAI (not stock) hitting something else inside the engine area. When they put the new engine in the tech adjusted the CAI a little to low and when you hit a bumpy area it was causing it to hit another part. No damage done he readjusted the CAI and so far so good.
