Heavy smoke, please help

[mhrallyteam]

I left home this morning, first five minutes everything's fine. Then when the engine got hot HEAVY smoke came out of the pipe, oil smoke i would say, this was idling at a stop light.

Then i ran a while and it dissipated a bit, but at WOT a blue puff appears in the mirror.
It is the second time this happens, firts time i replaced the old turbo with a good TD04. I tought it was gone bad. The block is a wrx one with maybe 40thousand miles max, so i highly doubt it as blow by.

Any ideas guys, the temperature here is below freezing by the way, could my air filter be dirty/frozen enough to cause my engine to suck oil from the block, anybody else having trouble with their turbo in cold weather. Thx for any comments guys

Usually it's the opposite, when my uncle starts one of his trucks it smokes until the engine heats up then it stops being visible. In his case, the oil rings are bad but the compression rings are good.

Well... No smoke anymore, which is good but i still don't like it. How could a turbo leak a lot and then not leak at all.

My legacy did that for a while, it smoked a pissload, then i was taking it up to my uncles house a couple days later to pull the engine and look at the rings and it just stopped all of a sudden. Never figured out what caused it.

its the wheather if you live in canada it happens all the time, i get scared like that becuse if it dont stop, you blown a piston or turbo one of the two.

dont worry about it guys its mother nature fooling you guys, and turbo cars make a little more smoke then n/a cars, becuse the turbo.

thats a funny store, i all ways run to my dad and say there is smoke come out the exhuste like crazy!! i think the pistons just blew up, he says MA YOU CRAZY its A cold out'a side'a hahahahhaha

perhaps one of the oil rings stuck, then freed up, was this a fresh installed engine?

mine wasn't, I think the engine had been in the car for 120k miles. After that night I ended up having to replace the engine anyway, due to a friend's driving.

The weather sure has something to do with it, but i wonder how can oil leak into the exhaust when the engine is not running. The turbo being higher than the oil level.

You don't have a small crack in the block do you?

I sure hope not! We had a couple of cold days since and no sign of smoke yet. So, im happy
