What owners wrote
Dealer advises warping of exhaust manifold caused exhaust studs to break. Also states that this is a common problem with this vehicle.
Exhaust manifold studs have broken on both manifolds at an estimated repair bill of $800. We have no choice to have it repaired as we cannot receive our emmission test approval to get our vehicle registered (1990 pathfinder) there is no warning for this defect and it was not detected last may because it did pass the inspection at that time. The bolts on the valve covers work themselves loose and I am able to move them with my bare fingers.
