lately i realised that there is white smoke came out from my exhaust when i high rev and switching gear.
Knowing that white smoke is not normal, might be my turbo or enjine. But is there any other posibility?
But it still producing same power as usual or might be abit less power, confusing
Anyone can help me out here will be great thx...

maybe its a puff of fuel vapour? running rich etc

rich = black smoke
oil = brownish or blue smoke
water = white smoke

Does it happen all the time? Even once warmed up?

If it only happens when cold, then its just condensation in the exhaust pipes. No biggie!

But if it happens all the time, the only way water can interfere with the combustion process is through the head gasket. Check your radiator header tank, if it has a wierd froth to it you have oil in your water. Check you oil, if it has a milky white brown colour to it, you have water in your oil. Together, it means you have blown a headgasket.

One of two things.

1. Stuffed turbo seals
2. Excessive engine blow-by

It could also indicate a malfunctioning PCV valve, so it might be worth changing that. About 30 bucks from Subaru spare parts, and about 10 mins with a spanner is all it takes to change it.

turbo seals.

Lol, hopefully it is just the turbo seals. Dunt wish to have any more than that. If it is the turbo seals, is it fixable or i'll have to change another new turbo?

Just change turbo. VF turbo's are the best value for money, wouldn't even be worth fixing it. BUT ensure its the turbo thats damaged not a split oil feed line, or worse the engine. Take it to an experienced workshop and have them check it out for you and give you a diagnostic IN WRITING.
