How do you replace the crankshaft front and rear oil seals on BMW Z4?

To replace the crankshaft front oil seal, follow the timing chain cover removal and installation procedure. For the crankshaft rear oil seal, begin by removing the flywheel/driveplate. At the bottom of the oil seal housing, unscrew the bolts securing the rear of the oil pan to the housing, then unscrew the bolts securing the oil seal housing to the engine block. If the housing is stuck to the oil pan gasket, use a sharp, thin blade to separate them without damaging the gasket. Withdraw the housing from the engine block, gently tapping it with a soft-faced mallet if necessary, and remove the gasket. Clean all traces of old gasket and sealant from the mating faces, taking care not to damage the oil pan gasket; if it is damaged, install a new one. Support the oil seal housing on blocks of wood and drive out the seal from the rear using a hammer and drift, then clean the seal mating surfaces. Install the new seal using the seal protector, ensuring not to touch the sealing lip, and drive it into position with a seal driver. Ensure the locating dowels are in place, then position a new oil seal housing gasket over them. Carefully install the housing to the engine block, sliding the oil seal protector over the crankshaft flange, and push the seal and housing into place without damaging the oil seal lips. Reinstall and lightly tighten the housing-to-engine block and oil pan-to-housing bolts, then tighten them to the specified torque. Finally, reinstall the flywheel/driveplate. For camshaft oil seals, note that in a timing chain engine, sealing is provided by the valve cover gasket and timing chain cover gaskets.
