Renault Laguna 2002 (2.2 Dci) Water from Tank and smoke

Hi all, on our way to spain when the heater hose split.



Took it off, repaired it and started it, all OK drove 300 miles close to Spain Border, then overheating light

Pulled up, looked and noticed there is back presure and water blowing from Radiator head tank.



So, limped it into a french town, Yes its Xmas Day, no joy here for a while.



But, I am suspecting Head Gasket, issue is, what else.....:crazy:



This morning outside Motel room, I could not statrt it, so jumped it, and a white puff emmiting from number one injector area, got car started and still 1st injector puffing smoke, and yes water is pushing back through header tank.



So, I would like comments please? :cool:



Depending on those comment will make my nect move, get another car and dumpt this or spend the cash to remove the head and gasket etc.



Cheers
