- renewal

1 Remove the timing belt and crankshaft sprocket (see Section 5).

2 Note how far the seal is recessed in the bore, then carefully pry it out of the oil pump housing with a screwdriver or seal removal tool

(see illustration). Don't scratch the housingbore or damage the crankshaft in the process (if the crankshaft is damaged, the new seal will end up leaking). Note: The seal may be easier to remove if the old seal lip is cut with a sharp utility knife first (see illustration).

3 Clean the bore in the housing and coat the outer edge of the new seal with engine oil or multi-purpose grease. Apply a little grease to the seal lip.
