1995 ls 400 runs fine no werid noises but all of a sudden I have white smoke coming out of exsaust on when i start it.
Will the white smoke go away after a few minutes of running? If it does then it most likely just condensation in the exhaust system due to weather changing. If it doesn't then you have a possible blown head gasket or a cracked head, watch your coolant for a drop in the level or oil contamination, also watch your engines oil for coolant in the oil. If none of the above appear to be happening and your still concerned you can have a shop run a block check.
