Default Cam positions

Hello, i have tried to change cambelt on my Peugeot 406 year model 2003 with 2l petrol engine. The thing is that the exhaust cam lock pin fell out and now i dont know the right positon. I have seen in posts here before and i have locked the cams like on pics (lock pins also on flywheel\crankshaft). What positon should the exhaust cam be at? The first two lobes (close to cams) are pointing 11 clock.

You cant really tell by the cam lobe position as these engines are timed with the piston half way down the bore so the cams are not where you would expect on a normal engine !

As long as you are sure the pins are correct then the timing should be correct there are a few threads regarding the 307cc and gti 180 timing pin locations on this site and the timing method is the same have a read on them i think there were some pics posted.

The exhaust cam, I am not sure that the cam i aligned correctly, what markings on the cam do i go after? It is B-mark on cam where the lock pin is.

If you remove the belt and manually rotate the cam sprocket to allow the locking pin to be re-inserted then it will be in the correct position to refit the belt and tension up. It's exactly how you would have to do it if you had rebuilt the head. Nothing unusual.

That is no help, the cam have multiple holes, it needs to be in the right place, locked, where are the timing marks on this cam? It has a B-mark and a erosion mark on it.
Look at my picture is this right?

The cam pulley does indeed have multiple hole BUT should only have one timing hole. The two marks you call erosion marks usually line up with a white line on the timing belt when the pulleys are pinned. As for your assertion that the post that reliable linked to being of no help - perhaps you should look again as it shows the 'erosion' marks quite clearly.

Only 1 hole lines up with the locking pin hole the cam itself has NO timing marks the pins through the pulleys is the only way.

There are other posts with pics of timing pins installed if you search.
