Why are my exhaust manifold bolts breaking off?
Why are my exhaust manifold bolts breaking off?
I took my truck in this week for a few minor fixes and in a casual conversation with the senior technician he told me the number one issue with the Hemi is the exhaust manifold bolts breaking off during removal of the manifolds. I thought I would post this in case anyone is planning on changing out to some headers.
What to do if Hemi exhaust manifold bolts are broken?
Oh yeah, this has been an issue for years. And it seems Ram won’t change the quality of the bolts either. If you do, spray spray spray with penetrating oil and pray. My ’09 Hemi went in the shop 6 different times (IIRC) to have exhaust leaks from broken bolts fixed over the 10 years and 193K miles I had it.
Why are the bolts on my car breaking?
Corrosion simply refers to the exposure of the bolts to incompatible substances like oxygen, naturally occurring chemicals, or even other metal products. Bolts in automobile parts are more susceptible to chemical corrosion where bolts can be exposed to engine oil leaks or other fluid leaks, therefore causing them to deteriorate over time.
What to do if you have an exhaust manifold issue?
Be prepared with the proper thread repair and bolt extraction tools. Soak the bolts with penetrating oil overnight. Use a torch to expand and soften up the metals before removal. Remove the wheel/fender liners for the best access to the exhaust manifolds. If the manifolds are removed, replace the gasket.
