anyone have the same flywheel as me? early 2.4 aab. my camshaft slot lines up with the mark in the inspection window to the right in the first picture but after an extensive look round the flywheel i found the o I I in the second picture (iPhone camera on full zoom). this would put my timing out slightly if i should be lined up between the o and I. there are 2 pointers on my flywheel like in the first picture (are these something to do with the clutch?) and all the marks are within an eighth of a flywheel turn.
i am slightly concerned as my van has been to the garage twice this month after i broke down with a suspected pump belt slip. the garage got my van to run but it makes a pinging sound every other engine rotation. they said they could not get it running any better no matter how much they move the pump timing. the garage also said my cam belt is very worn. i am happy to change the cam belt myself but not knowing whether the cam belt or the pump timing is the problem makes it all very frustrating as the van pretty much runs fine except for the slight knocking. it seems odd though that the knocking only occurs every few engine rotations rather than being a constant noise. if someone could give me a clear answer regarding the flywheel i will at least have somewhere to start as I'm now at my wits end and just want her back to full health. I've never heard a engine running out of time before but I'm assuming as mine still runs and drives ok ish its not wrecked. all the best and thanks in advance for any advice

took some better pictures when i got home today. i also found a z or possibly a 2 to the left of the 0. the pic is upside down and the tippex is my pump mark so ignore that. i don't know if the z or 2 holds any significance? i assume from the last reply that the flywheel tooth to the right of the pointer in the second picture is tdc? if so my cam belt has slipped a tooth, which explains my engine pinging sound. i guess I'm lucky it didn't slip further. thanks for the replies so far guys. any further conformation would be awesome, thanks

I'm with you on the phone idea. That's what I had to do just to find those marks, you would think they could produce the flywheel with a more pronounced mark. Thanks for the reply, I will have another look tonight.

I have the rocker cover and the cam sprocket at the pump end off and the camshaft and lobes line up with the timing line on the head. With the camshaft lined up my flywheel shows the pointer in the first picture as the timing mark but as I have 2 of these on my flywheel I need to be sure of the tdc mark. I'm not looking to use where the flywheel is currently as a reference because I'm assuming my timing has slipped and I need to start from scratch
