Help needed water in cylinder :s

Hi all i have a 300tdi i changed the head gasket as it failed now its developed more problems. I had the head skimmed and preasure tested (it Passed) and rebuilt. but im still getting coolant into the front (1st) cylinder and losing water. I had coolant dripping out the injector too followed by blue smoke out the exhaust. As anyone experianced this or know what the cause of this maybe. cheers dave.

you will have to pull head off check bore and head ,cant say ive heard off it coming from injector hole before unless washer isnt sealing or is cracked in that area

sound cheers pal what do i look for on the bore? i sorted the seal on the injector thats one problem down lol

rusty crack may be very faint

cheers for that will whip the head off and look
