I have an Astra 1.6i GLS 16v and wonder if someone could just clarify which is cylinder 1,2 etc.. if i am facing the engine compartment are they numbered from left to right, or from right to left. ie. is the spark plug on the left number 1 or is it number 4? might need to change the HT leads i know the DIS module is numbered but just want to make sure that i connected each lead from the module to the correct spark plug.
Thanks in advance
du.
Then just do them one at a time?

left to right as you look
Most engines have No 1 at the cam drive end.
Number 1 is the one nearest the cranshaft pulley.
That engine has number 1 cylinder on the far left. The Vauxhall DIS packs have numbers on each connector....for your own peace of mind, you can trace the leads to the cylinder from the coil. FYI It doesn't matter if you put it on as if 1 was on the right anyway, plugs 1 & 4 fire at the same time, and so do 3 & 2. Therefore if if you 1 in 4, 2 in 3, 3 in 2, 4 in 1 it wouldn't make the blindest.
No 1 is always at the "front" of the engine (the end furthest from the clutch).
Does this include transverse engines and automatics? ;-)

Almost invariably No.1 is at the non clutch/torque converter end. but there is something that has no.1 at the gear box end, I can't remember what, though you are not likely to come across it, as it is something fairly old.

I think it was a Renault.
IIRC Renault 16s where that way round
The message from Duncanwood contains these words:
Cor - we had one of those. UKK798H - smashing car. Got into it straight from a B-reg Cortina and it was like riding on air.
Dad got rid of it in the end 'cos he got fed up with replacing driveshafts.
That sounds familiar :-)
