My passenger side rear header bolt was broken but only the head snapped off. I had enough sticking out that I could use some vise grips and twist it out. Whew!!! Lol

ooo, inside the head is tough. I think the welding a nut to it is the best route here. Drilling it may be difficult with the lack of room you have in there and you could end up damaging the threads and stuff. I'd take it to a shop that does a little of everything and have them take care of it.

I had to pull a head after trying the slot and flathead method and the bolt extractor bit method. Luckily I didn't mess up the threads, but in the end I had to pull the head anyway.

Have your motor mounts been bad recently? I'm starting to think that the rocking of the motor is what's breaking these rear bolts off.

+1 on this method, worked great for me in the past, that is if you are able to get access with the welder!

That bolt has plenty of access.

Yes... weld a bolt to it! Best idea. And my motor mounts were completely shot when i found that mine was broken on my old car. I was doing headers and new motor mounts at the same time as well as a new clutch so its a good possibility that the motor mounts have something to do with it.

Yes I replaced my stock mounts with CS about a year ago but I have no idea when this bolt broke. It's about 1 thread in the head so i think I can weld a small bolt to it. I am going to try that first before pulling the head.

Not to hot looking but worked like a charm after about 4 tries! Heads are staying on.

Good to hear!!! Congrats!!

Got a chance to look at my alternator wire. It's a good 3/4" or more away from the header in a solid location. Looks like when they pulled the bell housing to do the clutch, they pulled the starter and moved the wires around to the left side away from the headers. Everything else is nice and tucked away from them as well. I'm staying naked with them. No issues thus far. Only thing I may do is put heat socks on the wires when I do my next spark plug change.

Good work! Way better than pulling the heads and buying new gaskets & bolts!

Hey guys my kooks are 3 in and the B&B are also but the kooks cats are 3 inlet 2.5 outlet. Do you guys think it will hurt hp at all to keep the outlet at 2.5 then enlarge to 3 to reconnect to the B&B or should I cut the back of the cats and install 3 in pipe?

I think I may just do the adapter thing for now to get her back up and running and then have some 3 in tubing put in before the tune.

Just trade me your 3" B&B and I'll send you a 2.5" magnaflow catback. Easy fix! Lol
