Please if you need VIN let me know. But I am sure with engine model you can get the right timing chain positions.

We don't have this car in the states, but I found this info.

You have two cam gears (DOHC):

Intake Cam (rear):

Timing dot/line on sprocket - Points straight up (12 o’clock)

Exhaust Cam (front):

Timing dot/line on sprocket - Points straight up (12 o’clock)

Both cam gear marks should be:
1. Level with the cylinder head surface
2. Facing each other horizontally

Please upload an image or a short video in your response, so I can see what's going on.

Sometimes Ken it’s tricky, because the sprockets can be displaced, and sometimes don’t align with the can teeth’s. So if I could maybe have an image of the positioning of the camshaft, this way I can realign the camshaft sprockets.

Here is the VIn, maybe something more can come. Because I noticed similar engines with different timing mark positions.

Yep, we don't have the marks for this, but from what I know you need to lock the camshaft phasers before installing the chain. Can you see any marks on the chain gears? We don't need the marks if we split the camshaft lobes on the related cylinder #4.

What do you mean by this?

So if you put the related cylinder cams so they are splitting the intake and exhaust lobes (intake barley open on the up-ramp with eh exhaust barely open on the close ramp - about 4 degrees on each) you can get the timing right on the money, I do this all the time works great.
