Hi i have posted in queries but thought i d try this one to. Ive changed headhead gasket on my 2001 1.1 and got lost with the timing. After bolting down the new one i turned the the engine and the belt slipped i didnt realise and kept on turning. Do i nead to take the head back off or can i line it up another way cheers.

Never turn the engine using the starter motor after changing the timing belt.

If you haven't damaged any valves, simply pin it at TDC and re-tension the belt. that's a big if.

If you mean turning by hand, that's fine because you can't bend valves that way unless you're he man.

This is going to be a nightmare to describe.

You need to pin the crank, there is a hole in the block at the front of the bay. it's about 1/2" diameter. it's not that hole, but a hole above and to the left tight into the block. it's a 6mm hole, put the plain end of a 6mm drill in there and rotate the crank until it slots in. It goes into the flywheel.

As for the cam, well, it's an 8mm dowell or bolt you need for that, it should be close to lining up once you pin the crank.

Then you loosen the 3 bolts on the camshaft pulley and rotate it clockwise until it's fully at its extent.

put the belt on, tension it, then nip up those 3 bolts.

That's it

Rotate the engine by hand to make sure it doesn't hit valves.

Yes it should do, if not, you'll have to take the belt off.

pin the crank, take belt off then align the cam. it won't have gone more than 180 degrees out if that's what you're asking

If you have a plastic style oil filter, then yes. it's very hard to see.

Liek I said, it's not the bit 1/2" hole, it's above and to the left of it.

I know im jumping the gun a little as my timings not aligned yet (doing it as soon as its light) but my problem started when the belt slipped as i turned the engine (by hand). I had not tensioned the belt correctly. Can anyone tell me how the tensioner is best set. By that i mean how does it work, i slackened it to get the belt off and then re tightened the bolt after. It must have been in the wrong position when i retightened. Sorry if obvious but i havent worked on engines since my MK2 16sport back in the day lol, cheers.

Sust the tensioner and locked the engine. Problem i now have is that the 10mm cam cog aligher is way off where it should be. Do i need to take the head back off and re position it ???

Sounds like you have got it a few teeth out.
Take belt back off.
Remove the spark plug. And at number 1 cylinder put a long screwdriver down the hole.
You are looking for the dwell angle. That is where even though your turning the crank the screwdriver doesn't go up or down.
That is true tdc.
Turn cam to the mark in the head.
Lock it off.
Refit belt making sure all slackness is out of the long side of the belt.
Turn tensioner clockwise iirc.
Torque the nut up for the tensioner.
Remove the pins.
Turn over twice by hand.
Really should have got a Haynes manual.
