The ProMAXX Nino Exhaust Manifold Repair Tool mounts directly into the exhaust passage of the EGR side of the exhaust manifold on the Ford 6.7L diesel. Unlike other mounting methods that only use one of the two existing bolt holes, the Nino is engineered to remove both mounting bolts and not be restricted to one of the two mounting bolt applications. The tool uses precision engineered and ground guide bearings to facilitate precise boring of the damaged studs. The kit supplies heavy duty stainless steel locking inserts used to restore the original thread size and configuration without the need to drill any other parts. To use, screw in the inserts and set the locks for a permanent repair.
