Have had my '16 RAM w/ 5.7 Hemi in exhaust shop 6 times - no, I'm not kidding. They replaced all bolts on right side & gasket the 1st time. Within a month, was leaking again. 2nd time, replaced all bolts again, gasket, lasted about 3 weeks. 3rd time, replaced manifold & gaskets, replaced all bolts again, lasted another 3 weeks. 4th time replaced all bolts again, another new manifold & gaskets, lasted 2 1/2 weeks. 5th time, replaced manifold & gaskets, bolts again, lasted 3 1/2 weeks. 6th time, replaced manifold, gaskets & helicoiled all bolt holes, has lasted 2 weeks. This morning cranked up & it's popping again.....always on the right side, so it'll have to go back to shop again.
I'm thankful for my repair shop, I have only paid for 1 manifold & paid for labor 1 time. Shop owner has been warrantying everything, he is now at a loss as to what to do, says he has never had one that keeps doing this. We are both trying to figure out what to do next. Anyone have any suggestions.....please?
