If the engine has been removed from the car, disregard the following steps which do not apply. Begin by removing the torsional damper, followed by the water pump. Next, take out the crankcase front cover attaching bolts and remove the front cover from the engine. For big-block Mark IV engines, after removing the attaching bolts, draw the cover slightly away from the engine, cut the oil pan gasket flush with the engine block, and then remove the cover. Upon installation, ensure that the block and crankcase front cover are clean. Use a sharp knife to remove any oil pan gasket material at the oil pan to engine block junction. Apply a t-inch bead of silicone rubber sealer to the joint formed at the oil pan and block, as well as the front lip of the oil pan. Coat the cover gasket with a non-setting sealant, position it on the cover, and loosely install the cover by first installing the top four bolts and then two 3/4-inch-20 x 1/2-inch screws at the lower cover holes. Apply a bead of silicone sealer on the bottom of the cover, install it, and tighten the screws alternately and evenly while aligning the dowel pins. Remove the two ¾-inch-20 x 1/2-inch screws and install the remaining cover screws, then follow the removal steps in reverse order for the remaining components. For Mark IV V8, ensure that the block and crankcase front cover are clean, cut the tabs from the new oil pan front seal if applicable, and install the seal to the front cover, pressing the tips into the holes. Coat the gasket with a non-setting sealant and position it on the cover, then apply a t-inch bead of silicone rubber sealer to the joint formed at the oil pan and block. Install the cover attaching screws and torque tighten to the specified value. Coat the front cover seal area of the torsional damper with engine oil, place the damper in position, and use a suitable bolt and spacers to draw the damper into position before installing and torque tightening the damper retaining bolt, taking care not to damage the damper. Finally, install the accessory drive pulley and the remaining components in reverse order.
