Hope it's nothing serious.. when i put mine together it had weird noises, pulled the trans and spent a week inspecting every tiny bit and couldn't find a problem (even talked to cope and he basically told me if nothing is wrong nothing is wrong) eventually found tiny witness marks of TC bolts touching the block but it sounded like marble in a tin can, not the normal steady clicking of tc bolts... i'm sure you will find it.. hope it's not serious though
