I would also fit a new thrust ring, it is another £30 on the bill but they are quite soft metal compared to the crankshaft and may well be corroded or have a groove worn round it where the seal has been running.
does any one no wot size torx bolt it is on crank pulley my socket set goes up 2 e18 and that was 2 small is it a e20 or e22??and will i be able to replace the seal with the engine in the car(nova)??does that black plate behind all the pulleys need to be removed to change the seal???cheers

No, there should be enough room.
1) remove fan belt and cam cover
2) get E20 torx socket on end of E20 bolt and long breaker bar. The crank spins clockwise, put breaker bar so it touches the ground. Turn engine over with starter only (ie remove king HT lead). The BIG torque of the starter motor will easily undo the E20 bolt. Once lose, remove E20 bolt (you'll need a new one, £7).
3) remove cam belt.
4) slide off the bottom crank pulley wheel along with bottom pulley wheel still attached (no need to seprate them for what you want to do).
5) slide off the solid metal collor on the crank journal
6) you now can see the rear cam belt cover and the oil pump through the cover.
7) you can also see the oil pump oil seal. screw in 1 or 2 self tap screws, pull out the oil seal with the heads of the screws.
8) fit new oil seal (may have to hammer it in, use flat/wide drift)
9) slide on metal collor, coat with copper grease so it slides on easier.
10) refit bottom crank pulley.
11) fit new E20 bolt, tighen to 250Nm and then a further 40º
12) fit new cam belt and fan belt if required.
