Camshaft oil seal - renewal

Engine in-car repair procedures / Camshaft oil seal - renewal

1 Disconnect the battery negative cable and position from the terminal.

2 Refer to Chapter 1 and remove the auxiliary drivebelt(
3 With reference to Sections 2 and 4 of this Chapter, remove the auxiliary belt pulley and timing belt cover, then set the engine to TDC on cylinder No 1 and remove the timing belt and camshaft sprocket.

4 Note that the inner timing belt cover shares mounting bolts with the coolant pump - refer to Chapter 3 and remove the coolant pump.

After removing the retaining screws, lift the inner timing belt cover away from the engine block - this will expose the camshaft oil seal.

5 Drill two small holes into the existing oil seal, diagonally opposite each other. Thread two self tapping screws into the holes and using two pairs of pliers, pull on the heads of the screws to extract oil seal. Take great care to avoid drilling through into the seal housing or camshaft sealing surface.

6 Clean out the seal housing and sealing surface of the camshaft by wiping it with a lint-free cloth - avoid using solvents that may enter the cylinder head and affect component lubrication. Remove any swarf or burrs that may cause the seal to leak.

7 Lubricate the lip of the new oil seal with clean engine oil and push it over the camshaft until it is positioned above its housing.

8 Using a hammer and a socket of suitable diameter, drive the seal squarely into its housing. Note: Select a socket that beats only on the hard outer surface of the seal, not the inner lip which can easily be damaged.

9 With reference to Sections 2 and 4 of this Chapter, refit the inner timing belt cover, timing sprockets, then refit and tension the timing belt. On completion, refit the timing belt outer cover.

10 With reference to Chapter 1, refit and tension the auxiliary drivebelt.
