Blown turbo or valve stem seals ?

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 . There is oil in intercooler and inlet but not very much in turbo just tiny amount or could this have burnt off on my journey home

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

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

It also still boosts fine which is strange

I e been having a bit smoke on start up sometimes. I've been told that cause I drive it hard, oil residue enters the inlet/intercooler. Apparently an oil catch can will sort this. Have a bit research for yourself as I'm not that clued up on it. Don't think there should be any vertical movement on your impeller shaft tho mate

Doesn't sound like turbo if it is boosting fine and doesn't smoke once started, as said you could have a little bit oil in the intercooler, worth pulling that off and having a look.

Just got your message, I can rebuild it for you if that's what you want but what you are describing doesn't sound like a turbo issue.

Had a bit of research into it , a few said catch can some said piston rings and another said stem seals , rocker gasket is leaking too but not sure if that would cause it .

Since buying the car I did a oil change and done like 300 mile and nothing measures on the dipstick , never smoked on boost or anything , it's a strange one ! Compression test tomorrow it is !

Someone else with engine trouble lol. I know how your feeling mate.

Total nightmare mate , having only had the car for 4 weeks I've had loads of problems ! Had a old classic which was exactly the same . To be fair probably my driving haha

I had mine for 10 months when I needed a engine rebuild now the gearbox needs replacing hopefully tomorrow I got the car on the 2 jan 2013

when my turbo shititself was ok till it started warming up then filled the street with smoke     could have had something to do with 1.4 bar flowing through the system     

good luck hope its an easy fix

If you want to swap engines over just let me know  

Found out cyclinder 3 has shit itself
