Default Newbie here and not too happy

Ok, got my 14 STI back in April and now with 13k miles on it, it smokes on start up white color and revving it a little it'll smoke but not real thick. Well got the engine warmed up this morning and loosened up the oil cap and smoke was coming out from there. Also, I've noticed lost in power the boost is still around 16 17. I was hoping I got some bad gas but with me reading all about this problem doesn't seem like it is just bad gas. And last thing I noticed it doesn't sound the same when it cranks, sounds like lose of compression. I thought Subaru's were suppose to be pretty good cars or maybe I just got a bad one, lemon.

The car is stock with a nameless CBE and that's all but it's been on the car since it was almost new. 13k miles seems a bit early to start having problems.

Do you watch game of thrones??
There's a character on there named Hodor. Imagine his name was Warranty, and he was talking to you, like, a lot.

Warranty. Warranty. Warranty. Warranty. Warranty. Warranty.

Bring it to a dealer. You are well under both time and mileage on the factory warranty.

What did Subaru say when you took it in to have it repaired under warranty?

Have you been keeping up with the maintenance or have you not changed the oil in 15k miles because it says it has a "15k mile guarantee"?

What are you monitoring boost with because first of all you should not be hitting 16-17 psi on the stock tune. Smoke from ringland failure is generally bluish color meaning you are burning oil. Have you checked your oil level? like others mentioned you have a warranty use it. FYI white smoke on start up can easily just be condensation.More noticeable with a aftermarket exhaust. Smoke coming from your oil cap doesn't sound good. Either your boost gauge is inaccurate or your driving your car with bad habits.

White smoke usually means water/coolant. Cracked head, gasket or other water related issue could be your issue. Check coolant level, look for telltale oil in radiator/coolant tank. Run don't walk to dealer for warranty repair.

Read the threads on ring land failure to see if your issue acts the same.

seems to me he is possibly over reacting. He stated it's a little bit of white smoke on start up. Only thing I see concerning is the smoke from the oil cap and possibly his driving habits depending on the accuracy of his boost gauge.

With the 2015's I know Subaru says it's normal to go above the target peak PSI. I forget what the numbers are but I think it has a target peak psi of about 17 and people are seeing the boost gauge peak around 22. Something like that, but either way Subaru says it's normal. I know the 2015's have a different turbo setup so I'm not sure if this logic applies to the EJ setup. Food for thought.

You are correct about the new model. Not the case with his.

I'm using my boost gauge to monitor my boost?? Idk what bad driving habits are considering it's never been revved over 5k. And it's not condensate when it's 120 degrees outside. Oil was changed at 7k.

Copy that, just double checking.

Yeah, take it to the dealership.

Obviously! lol what kind of boost gauge? Because your gauge is either inaccurate or your over boosting. There is a very bad habit that can damage your engine easily and it starts at low RPM's. Have you been going WOT from low RPM's in high gears? That's the only way I can see you hitting 17 psi on the stock tune and it's very hard on your engine. Also no way I would run the OEM oil for that long. I won't even keep T6 in my car for that period of time.

Here's the update: lol bad gas, idk if it was watered, too much ethanol, wrong octane in the tanks or what but they drained the tank and done the fuel system cleaner BS and put about 5 gallons of real gas in it and now it runs fine. They said bad gas will cause those symptons and after i got it i put 100% 93 octane in it even tho its 4.19 a gallon, but ill start driving the old twin turbo cummins more since its about 25 - 28 mpg over the subaru that gets maybe 12 mpg going downhill out of gear.

WRX gets about 100-200 MPG going downhill out of gear. The highest I've pushed mine is ~360. You should never run anything less than 91 octane, 93 preferred. I don't have 93 where I live and our gas sucks to begin with. I don't know why you'd think that its alright to run less considering you're complaining its $4.19.

I'd kill a man to get 100-200 mpg. That'd be awesome!

I'm assuming you meant miles per tank? There's no such thing as miles per tank.

Also, someone correct me if I'm wrong, but with the car in gear and coasting, don't the injectors shut off or go to minimal duty? With the car coasting out of gear, the injectors still have to fire to keep the engine running.

What gas did you have? 87oct?

As for your WRX MPG, you're probably clueless. I'm guessing you didn't even check what it gets. You compare your WRX to your "old twin turbo cummins" that probably has an 85 gallon tank then you say "Geee I can go a whole week without filling up! This thing must be efficient!".

I keep a very close eye on the real time MPG. Going down hill in gear my WRX gets about 164mpg. My normal commute is about 75% highway @ 80mph and I still manage to get 20-22mpg. If you're getting below 20mpg (in summer) it's your driving habits. With a cruising RPM of almost 3500rpm (~80mph) 20mpg is respectable.

That's what I always thought but as I watch my Accessport it seems like it [efficiency -- neutral vs coasting in gear] depends on the speed you're going. I notice at lower speeds Cobb reads a higher MPG with it in neutral instead of coasting in gear. I don't recall the exact numbers but either way it's still reading about 100mpg. At higher speeds it seems to prefer to be in gear more and my max is usually 164mpg in gear.

Blueish/Whiteish smoke can be difficult to distinguish, albeit the smell can be a give-away. Coolant smells sweeter, and oil smells kinda like a tire fire.

My car had the exact same symptoms as yours; its currently at TurninConcepts having a built motor put in after I did a compression check. Yep, you guessed it folks... cracked ringland. I had previously hoped it was oil blow-by, up until the point I saw a could of smoke behind me in the rear-view under WOT.

One notable item I noticed that seems to be shared was a rougher idle than normal.
