broken header bolt so in the process of cleaning up my my project z28
shes a 98 and has a bad exhaust leak on the driver side head. there is no bolt showing on the very last hole of the stock manifold. this is how i got the car from the owner. when i reach back there and try to put my finger in the hole im pretty sure i feel something in there. so im guessing they snapped the head off the bolt.
now heres my issue and question. i have some used longtubes and y pipe laying in my yard. i want to put them on, but do you guys think i have any chance of extracting that bolt without removing the head? im glad its driver side atleast. more room. i was thinking if maybe after all other bolts are removed and manifold comes out would i be able to turn bolt with pressure plyers? hit it with thread loostener. from what i feel it seems like just the head snapped off and the bolt still reaches almost through the manifold.
any experience with this? if heads need to come off im just going to fix up some 5.3s. i just hate the sound of an exhaust leak.

indeed. the only issue is this is my only car. and dont want to have it down for more than a weekend. if i need to do heads the car will be down for more than a month. so i wanna make sure i can do this. if worse comes to worse i guess i can just throw the long tubes on and deal with leak. atleast car will sound better than with manifolds.

most of them just break the head of the bolt out and you can grab it with a vice grip. if its broken in the head you will have to take the head off on that side. heads are easy you can do it in a weekend. or do what i did on my silverado just put silicone around the port and and tightend the rest down. it 2 years later and still holding. retighten the bolts afer a few heat up and cool down cycles

As long as you can hit it with vice grips, should be able to pull it out. The factory torque is only 18ft/lbs. If it broke because the previous owner cross-threaded the bolt..... you'll probably have to pull the head and re-tap it. Won't know till you try.

i think its only on the lt1 what uses different bolt holes for the long tubes. i could be wrong though. that sucks if they cross threaded it. seems like im fucked. like said i wont know until i try.
someone also mentioned that they used silicone for a temp fix if i need to pull head i may use this method for alittle while with long tubes. just until i can afford some heads and get them done up. i dont wanna do this job twice. any insight on how that would work?

If it is cross threaded you might be able to re tap it while its on the car.
