SuddenSmoking bad on start up
 

Hi all,

Started my car this morning and big cloud of smoke came from exhaust , then cleared .. Drove it to work then left it and it did it again at lunch when I went to go start it again , smoke clears but can't really tell if it does when driving

The day before had it on a airfield doing 160+ then it cut at about 165 when it had revs to go , could this have been the finale for the turbo ?
Would I be looking at stem seals or would I have done the turbo in? There is play in shaft up and down a bit but nothing horizontal

Car is a wrx blobeye running 300+ on a vf48 turbo

What would I be looking at for a rebuild on the turbo ?

Also still boosts fine from what I noticed
