3.0 Exhaust Manifold Bolt Broke Off....HELP! SOS
The JBA headers for my 3.0 have been sitting on my workbench for 2 months and decided to install them yesterday evening. I had the weekend off and took my time. I unbolted the everything pre and post cats with no problems. I uninstalled the driverside exhaust manifold and installed the driverside with no problem.
THEN....I got to the passenger side....
I'm thinking wow tons of room to work over here, this should be easy, boy was I wrong. I start loosening all the bolts and proceed to the last top passenger's side exhaust manifold. SNAP....Now I panic. I quickly unbolt everything and get the exhaust manifold out. Bolt is broke below the surface....I drive all over town trying to find a close quarter drill with no such luck. I try my dremel and get a hole in the center but tore through 3 drill bits.
Also the Y-pipe doesn't line up at all on my 4wd.
Will an exhaust shop be able to blow out the broken stud on the manifold? I got everything bolted up but you can hear all the exhaust leaks. I can't redo the exhaust so I have to take it to a shop to have that fixed but I'm really concerned about the manifold driver's side bolt.




I'm kinda dissappointed with JBA and their headers being so far off from the factory Y-pipe.
Any advice....besides being bummed out.

I went to the exhaust shop today and got an estimate to fix the y-pipe. The guy I always work with over there acted like it wasn't that big of a deal to not have that last top bolt on and wouldn't recommend removing the head to drill it out. He did however recommend a guy over at Ford who does it for all the F-150s and Mustangs. I went over to Ford and asked him about it and he said it would be around 4.5-5 hours ($87/Hr) to remove everything A/C related and reinstall everything.
I haven't ever messed with and A/C system before and was wondering how hard it was to remove all those components. Or should I let them have at it? Heck if I could remove all that stuff I could easily drill that bolt out.

So you don't think I should take it to Ford?

I don't have a problem drilling the hole and retapping it. I can't get any drill in there to get it out. It's up against the firewall and the AC box housing. Got any suggestions?
I have the same problem, it broke off naturely and it leaks but not worth it to have someone do it or me to pull the entire head to get to it.
If you find somewhere to get a drill small enough to get to it let me know.

It's still too big. Anybody know what that black shroud against the firewall on the passenger side is hiding behind it?
I wonder if we could drill through the backside if we take off the vavle cover. I'm not sure if that bolt sits inbetween a set of valves or not.
