You must still have the timing wrong, assuming the valves are closing OK.

Could you have the camshaft timing out by 360 degrees?

The camshaft turns at half engine speed - one revolution of the engine turns the cam by half a revolution.

You can but it shouldn't make any difference - unless its a very old petrol engine with a distributer.

Did you lock the engine with pins?

or do it by eyeball,

and if you did did remeber cylinder #1 on these engines is at the flywheel end,

not the more usuall crank pully end.

Simple test is lift the top cover off so you can see both valves are closed on cyl#1,

That'll be the flywheel/gearbox end.

You don't say what engine it is but, If it's the 1.2 16v then you can lock the flywheel at TDC using an 8mm drill through the engine block under the starter motor. The Cam pulley has a mark that lines up with a mark on the rear plate IIRC.

If the engine is petrol remove No.1 spark plug and turn the engine so that the piston is at TDC. Remove the cam cover and see if either No.1 & 2, or No.7 & 8 valves are 'on the rock'. If they're not then the valve timing is wrong. No's 1 & 4 pistons move together as well as No's 1 & 4 spark plugs fire together, so it doesn't matter whether you time it up on No.1 or 4.

There we have it! It makes things much clearer knowing what engine it is.

Did you follow the correct procedure for installing the timing belt?

forgive me... I'm sure it's not this...
but when my belt snapped and bent a valve...
the motorfactors gave me the wrong size valve...
it was only by checking it next to the original that I found it out !

They gave me the right one to replace the middle one

Could a wrong size valve, or its seating cause the problem?
or a slightly bent stalk...

I dunno...just a wild guess..

Cheers
Liam

I've heard of cases where the hydraulic tappets "pump up", holding the valves slightly off their seats causing lack of compression.

I think that the wrong grade of oil was the cause. Not sure whether it's anything to do with the problem you have though.

I'd have also suspected that the engine would turn over very quickly with a lack of compression. Is the cranking speed normal?

I would not crank it over. You need to remove the crank pulley and inspect the woodruff key, you may have sheared it off. Regards Peter
