Remove the Timing Cover Pulley .
You might have to remove the radiator depending on location .
Prise out the old oil seal using a couple of screwdrivers or a dedicated seal puller ,
TAKING CARE NOT TO SCORE THE SIDES OF THE TIMING COVER .Fitting ;Get a good strong washer large enough to cover the old oil seal
Lubricate the new seal
Place the new seal in position
Place the old seal on top of the new seal as a pusher
Place the washer on top of the old seal

{ 4 } CHECK THE TIMING COVER PULLEY IS NOT WORN / SCORED AT THE POINT WHERE THE SEAL SITS .
Sometimes the leak is not the oil seal itself but a damaged pulley .
Either change the pulley for a good one or fit a Speedi Sleeve available from

If engine untried and Timing chain and tensioner of unknown quality then it is best to remove the timing cover to check / replace these components .
Unfortunately to get the timing cover off you also have to remove the waterpump .
Before you strip it get a couple of spare timing cover and waterpump gaskets as well .
On reassembly make sure that ALL the old gasket / gunge is off the faces and they have no scores on them from inside to out .
Fit the new gaskets using only grease { Just grease your fingers and run the gasket through them , coating both sides }
If you do fit a new timing chain and tensioner make sure that the marks are lined up as per the Haynes manual .
After fitting the new oil seal , fit the bolts through the timing cover and fit the gasket over the bolts . then take the cover and gasket to the block .
Easier to fit that way and helps stop the gasket moving .
Fit all the bolts nearly tight but allowing enough movement of the timing cover to centralize .
Slide the timing cover pulley into place .
Centralize the timing cover if necessary .
Tighten up the timing cover bolts .
Remove the timing cover pulley .
Fit the water pump , tightening the nuts up diagonally a little at a time
Fit the timing cover pulley and tighten the bolt
.
