The only way that bolt is coming out, is with something holding the crankshaft sprocket.

I didn't listen to mark first time around either... I then Learnt it the hard way from experience, after I broke the wodruff key off the original pulley

Got as far as getting the timing marks aligned on the cam sprockets and crank pulley and inserting locking tool but how do you know if the crank is in the correct place after the pulley is removed as there is no key on the pulley.
Looks like the pully could be fitted in all four positions thus throwing the notch out on the pulley by 90 degrees everytime.

Once the crank pulley is removed there is no way of checking that the crank timing is correct :-/

Ok I've sussed out the timing marks on the bottom of the rear timing cover and the notch on one of the bolt holes

I've now removed the crankshaft pully and the very tight bolt holding on the boss that the pulley bolts too.

 I had to make a tool out of a piece of flat steel bar to bolt to the pully boss and to the alternator fixing point to counterhold it

Now what?

How do I remove the boss part to get to the oil seal :-/

Just going to get the new water pump from Unipart, I really need to get this oil seal replaced before I change the cambelt.

Can anyone help? Please

once the bolt is out the pulley should just pull off  :-?

Pulley is held on by 4 torx bolts, that's off, it's the bit behind the pulley which won't budge :-/

Cheers Mark, I haven't got a puller

Is the sprocket on the oil pump connected to the boss?

In other words am I looking at removing the sprocket as well as the circular boss that the pulley bolts to or is the boss a seperate part?

[markey mark]

oil pump tends to be driven off key in crank boss should be a separtate part

Thanks again, is there any way to loosen it without going out to buy a puller?

wouldnt want to tap it with driving cam belt ! but could try a couple of large screwdrivers behind it gently

How about using a long M8 bolt in one of the 4 crank pulley thread bolt holes in turn, and use a sliding weight on it ie slide hammer? Or, similar idea, run bolt into the holes, grip it with a pair of Vice-Grips/Mole-Grips and hit them outwards. It shouldn't be tight.
On a similar set up I lost & ran over my crank pulley from my Manta cos I hadn't tightened up the crank pully bolt. Not surprisingly it stopped very quickly .....

Once the crankshaft nut is removed the sprocket should just slide off. You will also need to recover the spacer ring behind the sprocket and knock out the woodruff key before tackling the seal.  I punched two holes in the outer surface of the oil seal and screwed self-tappers into this.  It then levered out using a pair of long-nosed pliers.

Take care with the new oil seal. I had a bugger ir a job trying to get this back on and ruined the first seal.  These are £17 quid from Vauxhall, but I got another one from my local autofactors for a fiver.

I used wet and dry to round over the lip of the journal the seal presses over.  You need to clean this again thoroughly and liberally coat the journal and the seal lip with clean oil.  The second one went in just fine.
