Coolant leak (timing chain cover?)
That is a casting line.
The 4 long water pump bolt threads need to be sealed with Aviation Sealer as they go into the water jacket.
Also the lower 2 bolts on the driver's side where power steering bracket mounts to block.
Extream Warning, do not use too long of bolts on the 2 lower driver's front bolts or you can punch them through #1 cylinder wall and destroy your block.
