So i bought this car from original owners - older couple. completely stock, 68k original miles. recently my check engine light came on, i used a reader and it said MAF high input AIT low input and car running lean. i took my car into the shop and they fixed that issue. but they noticed that my car was burning oil out the exhaust in between 15k and 25k RPM. This only happens for a few minutes. i turn the car on wait till engine temp is normal then when i start driving it pours smoke out the exhaust for about 3-5 minutes then stops... could this be my pistons or turbo sealer? why would something like this happen with a car that has such low miles that hasn't been driven hard... yet.... also my heater works great when i'm driving but when i'm sitting at a stop light or something for a few minutes it gets cold... or when i sit for a while the engine temp goes up but once i start driving again it goes down. I'm new to Subaru and new to Turbo's.. what could this be caused from and what am i looking at in repairs?
- Thank you
