Hello, I own a 2005 5mt Subaru Legacy GT with a different motor swapped in (I believe its an EJ205?) w/around 180k miles on the odo. This is also my first car.
I bought this car in January of 2023, and hasn't given me many issues besides power steering fluid disappearing and oil burning and leaking in some spots. Runs good, goes fast, DAM is steady at 1 always, no overheating problems, just burns oil like hell.
I noticed the oil burning recently (about 2 months ago) and have been topping up my oil weekly with Royal Purple 5w30. I see temperatures in the mid 70s to low 80s right now in PA. Now, the oil doesn't go by so fast that its always on empty when I check it, and there are no oil stains where I park that I've seen.
When I start the car, and start actually driving it, its either no blue smoke or a fair amount of it comes out the other end along with the regular condensation and burning of carbon I'd see. I ONLY notice it when I build boost, but for some reason its very inconsistent. There will be a noticeable amount of blue smoke behind me where I'd do a pull, but sometimes it doesn't. When I'm at idle, and rev in neutral, blue smoke also comes out the exhaust but only when I go into boost. So I'm thinking it may be a turbo issue, but I'm not entirely sure.
Something else that is concerning, is that under the turbo there is oil leaking from the bottom of it, and there's what I believe is a return line for oil or something that's kinked where its coming out of as well. I can upload pictures if need be, it's just a pain in the ass to get a good photo of it. After doing a pull and coming to a stop, a small bit of smoke will come out of the hood as well, not enough to be super noticeable but you can see it reflect in the sunlight.
I've been using my accessport to log data for TPG Tuning, they said they'd be able to help me out, I just wanna get a few opinions from here first.
Also I'm fairly certain it's not the stock turbo. I attached an image of the engine bay. I've literally just been dailying it to school and work and haven't had time to run through the car with a fine tooth comb. Any help would be appreciated. Also before someone asks me, "why did you buy the car without a build sheet" or alike, I needed a car and in my price range in pennsylvania this is as good as it was probably gonna get, car is completely rust free.
