Ok got the video to upload. The car runs perfectly fine! You can hear the turbo spooling and nothing feels off. To answer your question of whether it has good power? I don't know since I never drove an RB before. I own a 09 wrx so if I were to compare the two, the wrx reaches boost a lot faster (Rb takes forever) and pulls a lot harder and my wrx is currently stock. I do suspect something is off with the boost since it doesn't pull as hard as I would expect an RB to but maybe that's just my unrealistic expectations. There are no other issues I've seen with the car other than burning oil and this noise. No black smoke or any visible exhaust fumes. Like I said, I was hoping that it was just low on oil and the 3L that was left is low but not AWFULLY low. But I changed that and the noise remains. Engine temp is perfectly fine and has never gone over 190 even on full throttle and 30 min drives. This is all I've checked so far. I am new to RB engines and am at my wit's end. Here is a video of it about a week prior. The only problem at this point was that injector #6 was on and off but since then that has been resolved.
