I�m replacing the bank 1 catalytic converter on my 996 and one of the bolts on the manifold flange is so rusted it will not come out like the other two bolts did.

I think I had to use a chisel and 5lb sledge to break a couple of those bolts free.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I�m replacing the bank 1 catalytic converter on my 996 and one of the bolts on the manifold flange is so rusted it will not come out like the other two bolts did. I was able to cut off the nut, but the bolt is frozen within the two flanges. The hex head of the bolt is quite rusted as well, and I�m afraid it will round if much torque is applied. I�ve used copious amounts of PBBlaster and have heated the bolt red hot twice. Looking for advice on how to proceed.

While you have everything off, worth it to do a pass with sandpaper or an abrasive wheel to remove some of that surface rust around the bolts. Cleaned up parts work better anyway. 😋
Yeah, tried that. Will try again. there’s not a lot of room with the bank 2 muffler in place and that is held on by bolts that are even more rusted, and definitely don’t want to tweak or break the manifold. Ah, the joy of working on elderly cars that aren’t garage queens.
Finally got it free. Now trying to get it out! The #2 cat is in the way. Tried to lower engine, but last tech to work on car tightened motor mounts to 1,000 ft-lbs. Now researching how to remove rear bumper.
1. remove top edge fasteners accessible with the engine lid open
2. remove rear L/R light assemblies (Optional but easier on the way back)
3. remove all fasteners at the bottom edge of the bumper
4. Remove one fastener in each wheel well area, it's upside down (screwed in from bottom to top), it's holding the very front tip of the bumper to the fender
5. Grab front edge of the bumper, firmly pull out to the outside to disengage the bumper from the fender. Disconnect the bumper light connector at the center of the bumper.
That will take care of the bumper cover. You can figure out the rest ... the heat shields, the actual inner bumper... their fasteners are easily visible.
