Anybody ever have a loose bolt on your flexplate? If so what were your symptoms? I have a vibrating noise coming from that area under easy to mid acceleration. I recently rebuilt this motor and reused the old bolts that bolt to the motor. (I posted up before re-using them and people on here told me to re-use them with a little blue lock tight which I did) Pretty sure I used ARP ones to the converter. I haven't crawled under the car and looked in there yet but will tomorrow morning. Just looking for posts from people who have had loose bolts on the flex plate. I don't think its motor related or a mount.
