Head Gasket Daihatsu Charade 1.3cc Auto

Forum: 

Hi. This is my first post in this forum asking for help.

My Charade 1.3cc auto 97. is emptying the water from the radiator and there's a lot of white smoke so I assume from the forum that I have a head gasket problem. Also the oil is brown and creamy like mayo. I have spoken to several mechanics and they said that there's a big percentage that there is a crack in the block. Is it common in these type of cars to happen? If this is the case, can I send the car for a head gasket repair and then use holts wonderwelder to seal the crack?

Please guys give me a hand here. Appreciate any help.

Thanks

Ed
