Oldsmobile 1647477 Cover Seal

The 4.6L engine has a camshaft seal which is situated to the rear of the water pump pulley on the front (left) bank of cylinders, the camshaft being part of the retainer bolted to the cylinder head. Start by unlatching the water pump drivebelt from the water pump pulley, after that, you may have to do away with the dust cap, which is normally a plastic one, found at the mid-part of the pulley. Subsequently, disconnect the water pump drivebelt tensioner, and then employ a special puller so as to take out the water pump pulley from the camshaft. After that, one needs to unbolt the camshaft seal retainer from the cylinder head and clean the vicinity of the seal bore with a distinct absence of oil, debris, and gasket material. Replace the camshaft seal and its retainer and tighten the bolts to the recommended torque. Then, reinstall the water pump pulley using a special installation tool which can be ordered at most of the auto part stores. The remaining phases of the installation are quite the opposite of the removal and lastly, start the engine to be sure that there is no leaking at the camshaft seal.
