Stripped bolt head at over pipe/front pipe connection, what now? :( - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

BBYZILA · 06-02-2015, 01:45 PM

Hi everyone, I was trying to install my UEL catless headers yesterday. In order to do that I have to remove the overpipe and front pipe. The flange that connects the overpipe and frontpipe (see above) was really rusty, and I stripped the head of the bolt on the front pipe side. I just stopped then and there because I am not sure what to do now at this point. I believe the bolts on the overpipe are welded?

Can anyone help me out? What should I do?

Thank you in advance.

I don't have a solution, but to avoid this happening again, spray the bolts down with PB Blaster and let sit for a few min before wrenching. Stuff works miracles.

When this happened to me, we had to weld a new head onto the bolt and used a breaker bar... Only used the breaker bar and not any pb blaster because we needed to get some frustration out.

Work harder, not smarter... Errrr...

this seems to be the best solution currently, ill keep this in mind and bring it in to a mechanic. I dont have the tools or the skill to dig my way out of this hole. I have certainly learned from my mistakes, will be pbblasting every rusty bolt before i torque it. fml..

I ran into the same problem when I was redoing my exhaust. Since I was replacing everything I didn't care so much and broke out the dremel to cut off the other troublesome bolts. I think I only had one bolt come out easily and I had soaked all of the bolts with PB Blaster. I was less than thrilled at how difficult it was compared to other exhausts that I've done.

I can't remember if the rear of the front pipe are the same, but the front nuts on the front pipe are crimped or whatever to lock them in place. I was able to remove one, but the other locked up and took the stud with it. I mean yes its not that helpful now, but this is a good opportunity for you to find an excuse to replace that overpipe.

troek · 06-03-2015, 10:19 AM

you stripped the nut, that is threaded on the stud of the over pipe. if you mess up the the threads on that stud, you will likely have to drill it out, and replace it with a true bolt/nut combo. I would (option one) pony up, take your car to an exhaust shop and have them remove it and either clean up the threads and apply high temp graphite grease so it dosnt happen again, or drill out the stud and replace with a bolt/nut setup. Option 2, use a dremel or something similar and cut the nut off, remove the front pipe, drill out the stud your self. the chances of you removing the nut your self without damaging the threads of the stud are pretty slim.

Back in the day, before PB Blaster, WD-40 and fancy adjustable sockets, we used to give the nut a shot of coal oil (kerosene) and wait a minute.

Then, heat the nut up with a torch, then take a cold chisel and either cut it off or make a notch in the nut and pound on it in a counterclockwise direction until it either loosened up or split and came off. Be sure to use a BFH (big f _ _ hammer).

OR, as mentioned above, take it into a muffler shop, before you screw it up even more ......
