Hi,
I am after firing order direction looking from front of car (left-to-right, right-to-left), confirm that it is 1,3,4,2. And timing marks. The crank lines up with mark on block while the cam mark is lined up vertically with the top?
NB: the model is Cielo
Cheers,
Damon

I'm not familiar with the engine so can't comment on your detail questions, but firing order on OHC and DOHC engines is normally made with number 1 being closest to the cam drive (belt or chain). I have used this technique several times in the past when working on unfamilar engines. For the order itself, your 1,3,4,2 guess is almost certainly correct and is what I would use too.

Be careful, PSA engines have No 1 cylinder next to the flywheel - No 1 at the free end of the crank does not always apply.
I'm not familiar with this engine either, but if it's a petrol engine with an old fashioned distributor, you can deduce the firing order from the position of the rotor arm and the ignition lead to which it points. Failing that, in the absence of any other information (unlikely), take the lid off and see what the order is when both valves of a cylinder are closed - with a SOHC it's easy to see.

I would be most surprised if it isn't 1 3 4 2, but, that isn't a guarantee.
In the absence of a manual, one way to be absolutely sure is to take the cam cover off, and look at the layout of the cam lobes.
Some engines - notably Fords, fire 1 2 4 3.
