HAVE A P0455 CODE LARGE EXHAUST LEAK

2006 Hummer H3 • 125,000 miles

I found the leak, broken exhaust manifold rear bolt. How hard is it to change and what is the average repair cost? How hard is it to replace a exhaust manifold bolt that is broken off and how much does this repair normally cost to repair. Have a p0455 large exhaust leak code so that made me start looking around my engine.

If the bolts aren't rusted into place, it isn't hard to do. As far as the cost, if you can, get a good manifold from a salvage yard. If you get it new, expect to pay around 200.00 for it. Then, labor will be around 2 hours.
