whining from engine?

Went out for a short spin this afternoon.
Still got that whining sound from the engine. Droped the fan belt to check if it came from the alternator or the waterpump, but the noice was still there.
It comes from the center of the engine above the distributor or the timing cover.
Could any of you guys have any clue what could be the cause of the noice.
It´s almost like something is to tight in the engine.
Here´s a video of the engine at idle
