Alright, so this noise started to occur in the engine bay a few months back and I've been starting to get annoyed with it. It's not a constant rotating noise, but it only happens at about 1,600 RPM's. It is definitely a rattle of some sort, but I can't tell where it is exactly coming from. I have only 2 thoughts on what it could be, either the exhaust rattling on the cross member / sub frame or the front / rear engine mounts are bad. From what I know, it might still have the original mounts still in there because they looked kind of old when I had the engine out. Also, I did put the poly inserts on them, which is why I think it would most likely be the engine mounts. I have a video so you guys can hear it, don't mind the sound from the intake.

Well I finally figured out what what causing the rattle. The bracket for the counter weight, on the front engine mount was cracked so it was being held on by a small amount of metal. So the vibration from the engine would cause it move and it would hit the cross member and create the rattling noise. It's very nice not having that sound anymore lol
