I have an 02 TBA with 10,000 miles. Exhaust manifold bolts are severely corroded. I assumed due to the corrosion on the stud & nut that hold the exhaust manifold to the head that the combination would be hard to remove. I have broken many exhaust manifold bolts removing them over the decades. So I saturated the 4 with PB blaster-same as Aerokroil but cheaper. Fortunately the bolts all came out quite easily. But the nuts are stuck or corroded on the studs. So I'll get new nuts & studs & use anti seize & not allow the new hardware to get corroded like the previous owner did. Anyone had this same issue? Did you use torque seal when installing new studs? Being the hottest part of the engine transferring the spent hot gasses outward seems common sense to keep this area clean, dry & free of moisture & stud & nut threads lathered in anti seize! Comments appreciated.
