Sorry guys, don’t know the correct name/part number of the seal in the centre of the image, td5, 2004, how loose should this be? I can rotate it with my fingers! Should it be replaced?
they shouldnt be loose but allways are theres an i ring that becomes flat so doesnt seal properly ,you can just remove it clean it then stick it back in with a good bead of silicone sealant around the o ring
