Can you please tell me the possible problems caused by the vent pipe dipping into the F&E tank below the waterline.

have 12 rads on the system , 3 not working properly so I repiped the cold feed and vent too close couple 150mm behind the pump that is fitted to the primary flow pipe then into a threeport valve , when I fired up the system the vent and the coldfeed got hot ,I was wondering if the dipped vent into the F&E might have caused this heat up ? . it's an old system and i'm wondering now if there might be a sludge block to these rads , the flow to these rads get's hot so far but the return is cold , the pipework is all hidden in stud work and rises high but now iv'e resited the pipework it should push any air do you not think ?
