Does anyone know what the specs of the threads are for the coolant elbow on the bottom side of the 912ul cylinder head? This is the one that is Loctited and screwed in. On removal from the head the internal threads of the cylinder head have been slightly damaged and we would like to cut new ones but need to know the thread specs to find the suitable tool. It was removed as per the manual with heat and unscrewing but still the threads stripped. Any ideas?
