Nuggets/sludge would be bad. Since the trans has been out and TC replaced with mods to the valve body anything is possible. Just start peeling away the layers until you get there.

The new flexplate didn't have wallered out areas where the head of the flexplate bolts sit like mine did....
Suspicious.... but pretty much all the used ones I see online have this wear??
I wish I had bought new bolts....but didn't think it through.... They seemed fine...This time I put a little blue loctite on them....
I thought maybe. Fascinating that there is so much wear. Yes, and they seemed torqued well enough when I removed them.The (6) flexplate to crankshaft holes look like they should. The flexplate is showing witness marks
where the bolts were torqued into place, but no lateral movement, the flexplate holes are still
circular, normal.
I wouldn't expect it either. I checked torque on these bolts numerous times including when removing them and they were correct. I didn't check how tight, just that they were torqued at least tight enough.On the other hand, the flexplate to torque converter bolt holes look to be ovalized. Is it possible that
there was some lateral movement between the flexplate and torque converter? I would not expect
this.
I'd like to think so. I even replaced the starter 3 times because it sounded like something tinging against something else.If enough lateral movement was occurring, then I'd expect that the shank of the bolt hitting
either side of the flexplate hole would cause an audible clicking/clanking? Was this sound the one
that you were noticing in the vicinity of the bellhousing?
Torque converter holes are oblong. attaching photo from online....but the bolt heads aren't oblong? I do think it's odd that only one of the torque converter bolts left wear similar to the flexplate bolts. The other 2 were smooth.... Not worn down....Are the same holes the same shape in the new flexplate? Or are the torque converter bolt holes
circular like the crankshaft to flexplate bolt holes shown in your photo? This will help to confirm our suspicions.
I reused them. They looked good but I had to soak them in lacquer thinner and use a wire wheel to remove the factory sealant or whatever that was on the threads. I do feel like that couldn't have been a good thing to neglect to address this last year in addition to not adding any loctite. The threads didn't even look like threads. That sealant is crazy...So these were cleaned and I put some blue loctite on them. Although sparingly.If I was your neighbor working with you I would be OK with reusing the (6) flexplate to crankshaft bolts.
What a great idea. Will definitely do this... Need to look into what's going on with lubing the crank? ..hmm..Haven't studied what that end has going on....///what ? a bushing/// a bearing???consider adding post-torque tattletail marks
They look factory... Haven't installed them yet. Little stressed about the reman converter I picked up. I've got exactly 1/8" from torque converter pads to the flexplate mounting pads when pushed back to transmission which is spec I guess...but, the next pad over seems to have more clearance..I can slip 1/8" bit all the way comfortably, probably fall out if I let go whereas one side just fits...would stay if I let go.........edit////just remembered I didn't torque the bellhousing to block yet...Just snugged up and my son snugged up the other side....maybe could be the reason.....Let us know what torque converter bolts you currently have

Well you did ask to verify . More like the hypothesizing didn't pan out..lolThe original flexplate suffering from "ovalized torque converter bolt holes allowing noise to be generated"
theory may be wrong
It may be the TC is starting to come apart. Trans filter and pan should be informative.
Went ahead and took the pan before proceeding with installing transfer case..etc...Nuggets/sludge would be bad. Since the trans has been out and TC replaced with mods to the valve body anything is possible. Just start peeling away the layers until you get there.
Added pics of the 3 mounting areas bolt sideBut still odd to me is , like the screenshot you just posted of my video, that is the only one of the 3 bolt surfaces that has wear that affected the depth of the metal. The other 2 are flat. Just witness marking more or less.... no wear,,,, I'll get a pic in a bit....
