This Doesnt Sound Good!(flexplate)

I have a 88' f-150 300ci I6, 4x2, and it has an automatic c6 trans. Ther is a very noticable clicking noise coming from abouts the bellhousing area. It is a constant ticking/clicking sound that increases with engine speed, no matter what gear it is in. I had suspected that this problem may be caused from a cracked or broken flexplate, although i am not sure. Also, I had replaced the tourque converter nuts, but that had no affect. Does anybody have any idea of what may be causing this problem? All help is much appriciated, thanx.

The origin of noise can be hard to isolate. Could it be you have a leaking exhaust manifold/gasket?

I replaced the nuts about 2 weeks ago and i did use threadlock. Also, im pretty sure its not an exhausts leak, the exhaust is well sealed.

Make sure the flywheel/tq converter cover is not rubbing. Remove it and check for shiny spots.

I think iv found the problem. Earlyer, i had gotten under my truck again, trying to once again diagnose the noise problem. So i had taken off the trans service plate to get another look at the flexplate and check the converter nuts once again. Though, this time, while i had the cover off, i had someone start the truck while i looked at all of the movments in the bellhousing. It turns out that the noise that i was hearing was actually the starter gear, it wasnt fully retractingfrom the flexplate teeth and it was slowly chipping away at it. I am glad to finaly see what was making that terrible sound, and that i am in no need of doing trans work!
