should i be worried?

it looks to me like this is a repair to the block but would like your opinion as most of you probably have more experience than me. If it is a repair what do i do?

one other thing , the 4th pic , is this where you would set the timing on the engine or is it something else?

The thing in the last pic was for a sensor that picked up on the dowel sticking out of the front pulley. This was only used for diagnostics and has no use to you now so it can be removed.

Looking at the photos again I reckon that is a repair.

Cylinder head bolts are meant to be hex head bolts but the one in that corner looks like a socket head cap screw. I reckon the block cracked in that position, It was then welded up the re-tapped to a bigger size, Probably a metric thread.

Luckily the outer row of bolts are pointless anyway and can be left out, so as long as the material between the bolt hole and the cylinder liner is solid, you should be fine.
