Almost at the point of removing the head, but first I need to take the cam sprocket off.
How is the camshaft locked in position to remove the bolt. I know I can't lock it from the other end. any specific tools needed? thanks

Easiest way I can think of is leave the timing belt on, put the IP locking pin in, and loosen the bolt.

Give it a whack with a hammer with the bolt loose one or two turns.
On the engines with the plastic covers, there is a small hole in the steel back cover that you can insert a small drift through. Smack the drift, and off she comes.

I have already removed the IP and belt so can't do that now. Is that how everyone usually does it.
In the Bentley it just says loosen it, which isn't much help to a novice like me. lol

I've also used the cam lock plate, or you can drill a piece of steel to hold 2 bolts that you stick through the holes in the sprocket, which is more of the proper way to do it, and similar to the VW tool.

Usually I drape some lead flashing around whatever cam lobe takes your fancy and then a big adjustable spanner will hold the cam still whilst you undo the cam bolt. Getting the wretched cam sprocket off usually has me cursing as mine is sintered (i.e. FRAGILE!) and sits smugly attached daring you to twat it with a hammer. Five holes, so no joy with a bearing puller, unless you hook it on the rim, (see previous !). Why wasn't there a slot in the cambelt backplate to avoid all this aggravation? ARGH!
Rant Over. :roll:

Couple of options for holding her steady:
The right size Crecent wrench will actually not touch the working surface:
But for 10 bucks the proper tool can't be beat:
Works on the IP sprocket as well.

That is really helpful. I will try the adjustable spanner technique, however I think I might be able to get a cheap pattern tool like the one in the pictures. Thanks!

I found that when you use only the cam lock plate to put the belt back on, the cam shaft timing slips a little when you snug the cam bolt.
I suspect the same will happen with the crescent wrench on the cam lobe.
The pully 'spanner' holds only the pully, and I've had allot less cam timeing monkey business when using it.

The cam lock plate I purchased was too thick so I found a file in my toolbox. Worked like a charm.
