Need help removing the flex plate bolts
I'm in the process of putting another engine and trans in my pearly. The engine went in yesterday. While under the car today, getting ready to install the trans, I noticed that the flexplate was cracked.
I figure no big deal, but the damn bolts are on so tight that I have rounded corners using a 6 point socket and cracked a socket using a breaker bar I started soaking them down with PB Blaster this afternoon, I'll soak them again later tonight and try to get them loose again tomorrow. If the overnight soak doesn't work what is the next step to get these bastards out??? I still have the crane handy and the engine can come back out with little work.

That sucks.
This is a good example to everyone else why we should never use thread locker on em. I'd say heat em up, but I'm not sure what that would do to the seal. I can't believe you rounded a 6 point! Was it a hardend?

If I take a torch to them, I realize it would probably affect the rear main seal, would it hurt anything else??

Flywheel and torque plate bolts can be a real pain since the heads are so short. The problem with most sockets and box end wrenches is the angled area above the actual grip area. This only allows a small amount of contact with the head of the bolts. One way that may help you out is to go out and buy an individual impact socket, preferably 1/2" drive, and modify it like in this picture.

I wonder if myetballs' contact idea will do the trick with an impact socket. Assuming it is all of them, and not just one or two giving you a problem.

I'll grind down a socket and try that first, I was noticing that the socket was having trouble staying "flat" against the nut.
Any other tips? Impact wrench or Breaker bar?? And yeah, it is all of them

I use an impact wrench to break my fly/flex bolts free. Sometimes when I'm in a jam I turn the regulator a bit over spec (my impact gun sucks anyway). If that doesn't work, breaker bar and big pipe come out.

The flat ended socket, and an impact wrench is the ticket...
If you have to heat them up with a torch, go ahead and replace the rear main while the flexplate is off (not a bad ideal even if you DON'T heat them up) So Dave,are you about ready for the Dragon Alcyone Meet?

Six down, Two to go
The bad news; The last two have been rounded off using a 6 point impact socket The good news; They are opposite each other, so my plan is to cut the heads off, that will leave six bolts holding the flex plate on, three, hole, three, hole Any thoughts???

Do you have a welder?
If you do, weld a nut onto the stripped head (weld inside the hole in the nut) Then it will give you something to get a socket on, plus the heat from welding the nut on, will aide in loosening the bolt.....

WOOOOO ****ING HOOOOO!!!!!!!!!!!!!!!
I got the last two out. I pulled the engine back out and used a grinder to turn the 14mm rounded heads into 13mm heads and took another rail on them with the impact wrench. I used my cheap impact wrench on them first to prevent twisting the heads off, it's around 140 ft/lbs and it didn't budge them. Then I took my heavy wrench that's rated for over 400 ft/lb and it struggled but pulled them loose. It's a beautiful sunny day (the forecast was for rain and thunderstorms) and things are looking good.
