2005 GMC 2500hd with 6. 0 liter gas motor. Left and right bank exhast manifold to engine bolts broken off in head. Leaking exhast fumes and causing my check engine light to come on. Gm need to have a recall on this due to the number of vehicles out there with this problem. This is also an emission problem due to it will cause the cat convertor to overheat. . Epa? thank you.
All exhaust manifold bolts are defective causing them to break, when they do the exhaust manifold separates from the cylinder head in turn directing all emissions from the engine into the air, and cabin of the vehicle. This could cause a fire if not corrected. One spark would set the vehicle on fire.
Broken exhaust manifold bolts. Front and rear manifold bolts have broken on both the passenger and driver sides. As a result exhaust manifolds are now warping putting undue stress on remaining manifold bolts and creating an exhaust leak. Bolts are steel, manifolds are cast, and heads are aluminum. Dissimilar metals, heat, and moisture have caused the bolts to prematurely rust and fail. Emissions dilution will not allow for a passing smog test in 2013. GMC refuses to address the issue at hand, even though this is a recurring issue on all v8 engines. Estimate to repair; $2500.
