Hi Werner
No, that does not look correct! In mid May a hole [3/8"] was provided to get extra oil to the rear cam bearing & earlier blocks were sometimes drilled for this, but not to timing gears. Looks like someone had a mishap or misguided attempt to improve lubrication. I personally would not worry ; at a later time if you have to take the engine down, you could get it fixed. Cheers.
