Mitsubishi Sign 2005

Greetings friends I have a Mitsubishi Sign 2005. From a week here is driving white smoke per escape. When I turn it on, this even fails. But smoke is not constant is when I accelerate, someone can tell me what fails is thanks

Hi Turbotar, I don't know if this car will take turbo, if so, disassemble the pressure sleeve of this to the intercooler to see if there is oil, if so, you are spent the caps of the turbo.
Another possibility is some broken valve retain ... or a lot of game in the valve guides, that this hot throws a lot of smoke. Look at the spark plugs to see which "oiled". Luck!!

*All this assuming that smoke smells like oil ...

Thanks Pana I am doing it, it is not turbo, maybe the valve retain
