Hey there! So, I've got an exhaust leak at the point where the exhaust pipe and the mainfold join. What's happened is that the spring bolts have rusted, and the lower bolt is completely broken. (Pitcure attached--hopefully) In researching possible fixes, I came across the idea of replacing the gasket there with a ball and socket flange. It seems pretty labor intensive, but that doesn't put me off so much as the thought that it may not be the best solution. (A little background--I'm new to the DIY car repair world, but have been successful at all the repairs I've attempted thus far [muffler and resonator, wheel bearings and brakes, oil change and coolant flush, and spark plugs]). Does anyone have any insight as to the best way to approach this repair?
