My 2014 ram 5.7 has broken exhaust manifold bolts on both sides. I fixed the right side about 6 months ago now the other side is broken. Does anyone actually know what it causing them to break? I heard it was the manifolds were warping. The last manifold I recently bought was on backorder. The dealer said the manifolds were on hold by the manufacturer for redesign or something. I wonder if the new manifolds will be any better?
