flywheel moves around and believe the torque converter is making a ticking noise

I have a 89 yj with the 258 and auto tranny. I got my motor redone and at first it was good. But know the flywheel moves all around and has a tick noise to it. I'm thinking my flex plate could be messed up or just the torque converter is making noise. Any ideas how to stop this

The flex plate is probably cracked. Pull the bottom inspection cover off of the bottom of the bellhousing and take a look. Usually they crack right around the bolts for the torque converter. If so you gotta pull the trans and replace the flex plate. Oh and get new bolts too.

its a new flex plate if that makes any difference. Before I rebuilt the motor the one I took off was cracked ito like 10 different pieces. I know I have the skillz to do it, but I am worried its not that and just something dumb. Also kind of sounds like a slight exhaust leak but when I put my ear to it the noise is coming from where the motor meets the tranny

When the truck is cold it doesn't make the noise as much, but it appears to be getting loader. Anway to visually see what's wrong, I really hate this ticking noise

Were you able to check the torque of the torque converter bolts? There's also the possibility that one or more of the flexplate bolts have come loose. That's where I'd start. Of course, to get to the flexplate bolts you have to separate the engine and tranny and you can evaluate the flexplate condition at that time.

I am thinking since the fly wheel is not straight it is tapping against that very thin plate between motor and transmission. It's a plate with teeth but it is not solid. It has a weld every few inchs and i'm guessing when they replaced during my motor rebuild the guy didn't weld it straight. I believe my exhaust is slightly leaking at the headers, the gasket only lasted a few months. I cannot put my hand by the headers to find the leak so what is the eat way to find the leak, and If I do find it can I solve it without takin everything off. Since I have an auto the headers hit the shifter linkage that and the pipe that goes from exhaust to intake manifold, makes it a true pain In the *** to change the gasket
