Default crazy turbo problems

so I bought my 08 wrx at 80k miles and 6k miles later my turbo blew so I got a new one and now 6k miles later I'm pretty sure its blown again although its having different symptoms. When it blew the first time, I had no power what so ever it whined like crazy and sounded awful, and this time I heard that whining noise again but after a little bit the whining stopped and I just had no boost from 3-4k it was like driving a normal boxer engine, I got home and went to reverse into my parking spot and I see a *****load of smoke pouring out the exhaust, a ridiculously huge cloud, i turned off the car, popped my hood and saw nothing visibly wrong with the engine bay, it felt hotter than usual but my temp gauge was reading normal the whole way home, after I turned off the car and looked around, I noticed there was still smoke pouring out of my right tailpipe with the car off, I thought maybe my car was on fire inside the exhaust, the smoke was white. It seems to calmed down now (15 minutes after shut off), does anyone know what this sounds like? I'd like to think my turbo isn't blown again and if it is maybe they missed something last time that caused it to blow, I don't drive like a douchebag, I never rev the car past like 4k in any gear other than first and thats only if I shift too late on a start, I don't beat on my car, my friend beats the living **** out of his 08 wrx and is still on his first turbo. I don't understand what could be causing these to blow, I had just been running on my usual backroads where I spent most of the time in third or fourth gear running between 3-4.5k rpms and I still spent the majority of the time driving between 2.5-3.5, 4.5 was the highest I hit, it was wet out so I wasn't trying to slide out every where. I have no idea whats going on with the car, I'm getting extremely frustrated, I am going to take it to get it looked at but I'd like to know what everyone here thinks it could be. Thanks guys

Oil level is normal, the car was a one owner vehicle. Bone stock, not beaten on at All, 26k miles a year should hardly affect the turbo especially since I just had a new one installed.

If the dealer changed the Turbo, parts and labor are covered unlimited miles as well for 1 year. I'm not sure if the 08 had a banjo bolt on the turbo like 07 and earlier WRX's. If so could be clogged starving your turbo of oil ? Just a idea ....

They say it's the turbo that's bad but they don't know what it is yet that caused it to be bad

Who is they? And who did the turbo? Your car had to be beat or starved for oil somehow, maybe even tuned and put back to stock. I have had 2 WRX's a 04 traded it with 105 k original turbo, a 07 traded it with 145 k with the original turbo. You should have never lit up a single turbo by now let alone 2. Something is certainly wrong.

well thats what i'm saying, The dealership has been doing this work, I feel like the first time the turbo blew they may have messed up installation. I bought the car from a crappy dealer so I wasn't surprised when the first turbo blew, but luckily I have this under warranty. The car fax on my car is clean, it was owned by a 40 year old male nurse its entire life, the car is very clean and aside from turbos I haven't had any engine related problems. I think there is something wrong with my exhaust though that might be an underlying cause to this problem.

i know this year had turbo oil line problems but after having one turbo replaced I would have thought that the oil lines would have been replaced with something better after the TSB about it. Whatever happened this time caused my exhaust to shoot mushroom clouds of smoke out and I couldn't even hear the turbo spool.

You need to find out why the first turbo went kaapoot because whatever caused that likely caused this one to go too. If the turbo was in fine shape when installed (I'm assuming it was new) then your likely options for failure are: oil starvation, bad install leading to no oil or no coolant circulating, or just a plain old faulty part (**** happens).

My guess was that the first one did experience some sort of oil starvation. What oil are you running? White smoke is usually an indicator of burning oil, and these cars are semi picky about what oil they burn and don't. Pop off your intercooler and look for blow by, this would be a good indicator if you have an oil issue.

Otherwise there is really no reason to be going throw turbos as an earlier posted also said. I beat on my 08 wrx for about 35k miles with it's original turbo and when I replaced it I was able to sell it in near perfect condition to someone else.

What kind of oil should I be using? I keep trying to tell the dealer to strip down other parts to find why it's blowing but they just insist that it's the turbo that's blown, I know it's blown but I want to know why >.<

What are you talking about? There is nothing wrong with using 5W30 in a street car.

Mobile 1 5w30 and Royal Purple 5w30 have been known to shear down early in our boxer engines (possibilly others as well) Around 2k miles they often will dip to a 5w20 and lower which causes alot of issues. I've actually experienced this frist hand when my 04 wrx spun a rod bearing at 3k on M1 5w-30. According to a few guys here on nasioc this has been confirmed by blackstone labs.

The crowd favorite here on nasioc seems to be Shell's Rotella T6 5w-40. There is tons of infomation on this subject if you google it.

clean out or remove the banjo bolt filter that's in the feed line to the turbo.

Blue smoke is indicative of oil, white is generally coolant and black is soot from fuel.

The objective is to ensure this won't happen again, from that a deduction can be done as to why it happened. Simple said not done.

Like stated above, clean out the filter, check for kinks in the feed line and also look into possible clogged up water lines (odd but seen it once where the coolant wasn't flowing back out of the turbo thus causing the seal to over pressurize and push coolant past).

The options for a turbo failure are grim, contamination and materials in the oil that clog the filters are more common than any, then kinks in the lines (water and oil return) and lastly, someone stated that you MAY have just gotten a bad turbo which in itself is possible, got a bad block before...that was one hard thing to explain to a customer but it was honored.

Quality of oil is also a factor in the longevity and performance of the turbo. An oil that is quickly broken down or sludged up (Mobil is an example of it breaking down into water and Royal Purple sill burn up and sludge up) will also help. Valvoline is usually choice for the Subaru's and whether you run synthetic or not, it's up to you. Subaru's contaminate oil VERY quickly (compared to other oe turbo manufacturer vehicles) and regardless of protection value or the viscosity tables it's tested under, make sure your checking it and changing it often enough.

If you are STILL going to be having problem with the car AFTER they fix it again, have them ship the car out to more competent technicians that can asses the vehicle, just to keep the warranty with out you informing them that you were fiddling with things.

All I want to do is leave it up to the dealer as that's the way to keep the warranty. They give you a rental, you drive it from A to B and when your's is ready, your golden. Something come's up prior to that and they can say that it was negligence or ignorant abuse of something. Dealers will find ANYTHING to take the warranty out of under you is the only point really.

You can do a compression test, leakdown and whatever, as long as the dealer doesn't walk up to you and say "Who else has worked on the car?"
