Hyundai 21421-25002 Seal-Oil

Pull out the transaxle, and then, the driveplate/flywheel should also be pulled out. Remove the Crankshaft Seal from the rear of the engine utilizing the seal removal tool or a head of screw driver mindfully not to cause any disappointment on the crankshaft or on the seal bore. Wipe out the mating face of the block by using a shop towel; make sure there isn't a single drop of oil or dirt on it. Apply grease on the OD of the seal and place it over the end of the crankshaft with the lip pointing towards the engine. Preferably that the seal installation tool be used to high the new seal into position and indicated that there is a requirement for a small oil drain in the separator to be positioned at the lowest level. If the proper tool is not with you, a large socket can be used to chisel and insert a new seal gently with an aim of getting it flush with the edges of the engine block. Lastly, fit back the driveplate or the flywheel then follow it by fitting the transaxle.

Lift the transaxle out of the car and then the driveplate or flywheel has to be pulled out. Whether it is a slotted or a solid Crankshaft Seal, pry it out from the rear of the engine using a seal removal tool or a flat-end screwdriver, risking the crankshaft or the seal bore. Afterwards, clean the seal bore area within the block with a shop towel to ensure that the area is free of any oil or dirt deposits. Apply oil on the OD of the seal and place it over the extremity of the crankshaft with the lip facing the engine. Ideally, a seal installation tool can be used to push the new seal back into its proper position while it is noted that a small oil drain in the separator must be in the lowest position. If the proper tool is not available, the big socket must be used to insert the new seal gently into the seal bore in a way they are perpendicular to the surface of the engine block and lies flush with the outer perimeter of the block. Lastly, bolt on the driveplate/flywheel, and then the transaxle.

No, V6 engines don't have a gasket between the seal retainer and the engine block.
