Have you checked to make sure all things are still connected ?? Blowing smoke usually means that the turbo is unhappy but because you have changed the oil line then maybe its come loose again or something easy!!

Go get a mechanic to check asap!
Not a Subaru...... Something MUCH better

NOPE..... That's shit too. Bus anyone??

K&N Intake needs a tune, makes them run lean and then the ECU detects enough engine knock to disable boost...

Yeah everything is hooked up. The intake has been on for a couple of months now n its only lost boost recently. My mate is a mechanic and reckons it might have thrown up a code

You will instantly see the dash light up if its thrown a code.
Are you using an oiled K&N filter, they can foul the MAF sensor and cause this sort of thing.

My mechanic mate reckons they can throw codes but they won't log so the engine light won't come on.

Anyway got it back to subaru yesterday and it is the turbo that has shat itself. Not sure exactly what is wrong with it as it didn't make any noise at all.

Glad I got the extended warranty now but fucking pissed off its gone back THREE TIMES

My money is on the BOV vacuum hose or intercooler to throttle hose having blown off.
Be careful as Subaru may void extended warranty due to engine mods as well :)

They're doing it under warranty even with the exhaust on it. Gonna ask to see work orders to so I can see what they have actually done.
