  1. With a small prytool, carefully pry the seal out of the front cover. Be careful not to damage the bore of the oil pump housing with the screwdriver blade.
  2.  
  3. Clean the seal bore out thoroughly. No dirt or grease should be allowed to remain inside the bore, since such foreign matter will cause premature failure of the new oil seal.
  4.  

To install:
  1. Coat the lip of the new seal with engine oil. Using a piece of pipe or a socket slightly smaller than the bore of the oil pump (and about the diameter of the seal itself), tap a new seal into place. Position the seal so its front edge is aligned with the front edge of the oil pump body.
  2.  
  3. Install the timing belt crankshaft pulley, timing belt and timing belt covers in reverse order of their removal.
  4.
