Just recently i have noticed that my 01 au2 falcon ute 6cyl water coming from exhaust on start up not alot but every couple of days have to add about 2oomls of coolant. There is no cotamination of the oil on the dipstick or cap i suspect there is a failure of the head gasket on exhaust side.I am fairly competent with toolsj and have the tools to do the job this would be my first attempt at doing a head gasket any tips would be appreciated.
