Broken Exhaust Manifold Bolt

Recommended Posts

2011 Silverado, 5.3L 1500 LT.  I noticed that the driver side FRONT exhaust bolt is broken off.  I can only stick a probe in the hole about 1/4".  I assume the head sheared off below the flange.  i know this is a common issue, but 99% of the time its the rear bolt.

Is there an easy fix?  they sell a bracket for the rear bolt breakage, but is there anything for the front?  or do I need to bite the bullet and pay a shop to get it out?

appreciate any input.

well - i was quoted $650 to replace all the bolts.  and if one breaks on them, take on another $65 per bolt that breaks.  then they told me that they would have to remove the head - and who knows what that will cost.


has to be a way to do this without head removal.

It is incredibly hard to do it without head removal. I suggest removing the head yourself and taking it to a shop. I got a total 4 bolts out of 2 different heads with disassembly and reassembly of the valves and valve springs, a cleaning and the head painted for a total of $220. Now for you it should only be like $60 if you take it to a machine shop. Mechanic is going to charge you more. 


You can remove the head yourself. It is pretty easy to do.

If you can feel the stud with your finger inside the exhaust flange, you should have plenty of meat there for a vise grips to grab it when the exhaust manifold is removed. I had two broken like that and I just used vise grips after I heated the surrounding area of the cylinder head with a propane torch.


If it's only got a little meat there to grab we just weld a nut to stud and try to remove it that way.
