Like the title says, I snapped one of my exhaust manifold bolts for the headers (I will get some pics up later but there is not really much to show).

I was still having some resonance from the headers so I decided to try and tighten everything back down again since I hadn't since the swap. When doing the one in the front all the way to the right, the bolt snapped about halfway through the headers. There is still a bit of the bolt sticking out. Do these bolts come out like the intake manifold ones where I could replace it or are they in there for good? Do I go about the same way replacing the bolt (ordering new from Acura) by just unscrewing and backing it out with some Vice Grips and put the new bolt in or am I pretty much screwed?


Is it OK to go for a little while with this not bolted down? All other 4 bolts are securely in place and the headers aren't going anywhere. The only reason I ask this is because when I made a vid during the install of my XS headers of me revving it with no headers on some guy made a comment saying that I was going to do serious damage and said that is was a "good way to burn up valves".




Thanks in advance

 

I would get it repaired sooner than later. It will probably cause leaks and in the long run be bad for that cyl. You will have to remove the header there to replace the stud. You should be able to get new studs.

Cool, thanks Kris.

I was just wondering if I should park it and get it fixed, or if I could just take it easy on it until I get it fixed; hopefully sooner than later.

 

fix it right away - what happens is a very small leak can exist which will pull colder outside air back into the exhaust ports- that may lead to a burned valve- expensive to fix

 

Well I did the repair today...


The broken stud


The front manifold off the car



Some more looks at the stud





Grabbed it with some Vice grips to get it off



The broken stud vs new one





To avoid the teeth marks from the vice grips on your new stud, put on a nut like so and tighten the stud down. DO NOT OVER TORQUE!!

 

the other method is put 1 nut down halfway the threads and hold it with a wrench- spin another nut down on top of it, holding lower wrench tight- pull the upper nut tight so they are locked together
now the bottem nut can be used to remove, or the upper nut to install, replacements.
Works good when installing intake spacers and some of the big studs get changed out.

 

 

your header manifold looks so much dirtier compared to mine... hmm...

but good job on the fix!
