  Q: How to remove and install the front crankshaft seal and front oil seal on the crankshaft sprocket on Volkswagen Passat?

  A:

  Remove the Timing Belt and crankshaft sprocket. Note how far the seal is recessed in the bore, then carefully pry it out of the front cover with a screwdriver or seal removal tool; if a seal removal tool is unavailable, the front seal can also be pried out with a screwdriver. Avoid scratching the housing bore or damaging the crankshaft, as damage will cause the new seal to leak. If a seal removal tool is unavailable, thread two self-tapping screws into the front seal to pry it out. Clean the bore in the housing and coat the outer edge of the new seal with engine oil or multi-purpose grease, applying grease to the seal lip as well. Using a socket with an outside diameter slightly smaller than the seal, carefully drive the new seal into place with a hammer, ensuring it is installed squarely and to the same depth as the original; if a socket isn't available, a short section of large diameter pipe will also work. Check the seal after installation to ensure the spring didn't pop out of place. If the front oil seal/oil pump housing on SOHC and early DOHC engines needs to be removed for access to other components, disregard the steps that do not apply since the timing belt is already removed. For later DOHC engines, detach the timing belt tensioner, tensioner pulley, tensioner lever, and idler pulley from the housing, then remove the lower Oil Pan. Loosen the housing mounting bolts and remove the housing from the engine while noting the installed position of the fasteners; the front oil seal housing can be removed with or without the front oil seal. In some cases, removing the front housing makes seal removal and installation easier, allowing the seal to be placed on a workbench and driven straight in and out of the bore without special tools. Before installing the front cover, ensure the mating surfaces of the cover, cylinder block, and oil pan rail are perfectly clean, using a hard plastic or wood scraper to remove all traces of gasket material, taking care with the front cover as aluminum alloy is easily damaged. Apply a 3/16-inch bead of RTV sealant to the oil pan flange on the front oil seal housing and to the front of the block where the oil pan and engine block meet. Locate the oil seal housing gasket over the dowels on the engine block and install the oil seal housing, ensuring to lubricate the oil seal lip before installing the front cover onto the engine to aid the installation process and prevent dry starts that may damage the seal and lead to future oil leaks. Tighten the front oil seal housing bolts in several steps to the specified torque. Reinstall the crankshaft sprocket and timing belt, then run the engine and check for oil leaks at the front seal.

  Q: How to replace the rear crankshaft seal and housing on Volkswagen Passat?

  A:

  All models are equipped with a one piece rear main oil seal and housing. The Crankshaft must be installed first, and the main bearing caps bolted in place before the seal and housing can be installed on the engine block. For the rear main seal replacement procedure, disregard any steps that do not apply since the engine is out of the vehicle and the oil pan is not installed.
