White Smoke

Hey guys a have searched and heard most people say it is a headgasket. So i did compression test and saw 150psi across all cylinders. The white smoke is very light only from the passenger side, there always seems to be water in the exhaust. Could this be a coolant line from the turbo?


thanks in advance
Tomas

Are you losing water?

Is the white smoke just when it's cold? Is there a noticeable water loss happening in the cooling system? (probably not because you said it was light) Does it smoke when it's warmed up? Does the water in the exhaust smell like coolant? When it is cold and you start it up, put your hand over the exhaust side that is smoking and then smell it...does it smell like coolant?

If the smoke is just light and only upon start up then it's most likely condensation. This is true especially if you put it to bed warm at night when it's cold outside.
