Default Ej205 problem

I have a 2002 wrx, let me state that this is the first problem I have ever had with the car and it's been tuned with larger injectors a vf22 turbo exhaust since 30,000 miles, I just turned 130,000 a couple of days ago. I noticed I was getting some oil drip on my headers/up pipe recently and found my oil feed line was leaking not too bad I would check my oil every couple of days and over the course of about 2 weeks I only had to add about half a quart, now here is the real problem, I was driving down my road and pressed the clutch in as I was approaching my driveway, the car cut off and I didn't know why. So I turned the key over and it was having a hard time turning over, then when it started it squeaked really bad for a second like a dry start or something and it wouldn't stay running, so I shut the car off and pushed it down my driveway(it's a quarter mile long wanted to kill myself) once I got it to my garage I checked the oil and it was on the low side but not below the low tick mark, so I added about half a quart and and decided to start it again and it was running and idling perfectly fine, but now when I rev the motor to about 2300-3000 rpm there is a loud knocking sound but if I hold that rpm the sound dissipates and goes away???? I was really confused as I'm not an expert on Subaru motors yet lol. So I decided to change the oil (as it was approaching anyway) and I decided to add an oil additive to see if that helped clean it a little as it has been fluctuating on oil level and gunking could be a problem so I changed it and drive it around but I still experience that knocking sound when I'm cruising around only when I slightly accelerate, when I put under a little boost or when I'm cursing at say 60mph at 2500-3000 it's fine I don't really notice the noise. I'm not quite sure what it is but I'm fully prepared to pull the motor out and pull it apart, I have rebuilt motors before but not a Subaru so I'm interested in talking a look, I have researched and found out a lot about my motor already but most of you guys are more experienced with these as I'm a v-8 big block guy lol so any help would be appreciated thanks! Sorry for all the grammar problems I'm on my phone.

Maybe rod knock. A video or a sound clip will help.

can you isolate the general location of the noise? Try narrowing it down by "listening" through the handle of a long screw driver or broom handle

I'm hoping I caught it in time to where the bearing is not welded to the crank lol really don't want that to have happened :/

A new crank cost about the same as getting one redone so I'd replace it anyway.

Literally It cut off I started it heard it knock and shut it off and pushed it up my driveway. Only cut it on to make a video and diagnose it

Well good plan.. it'll be much cheaper that way and the crank will most likely be much more savable. Have you drained your oil?

You can take quite a bit off to save them, even if not a sti crank is only 300 bucks same for 04 ej20s. And get some stronger rods and better bearings while your there

Since I don't think it's a spun bearing I shouldn't have to have the crank turned will I? Also what else could possibly be affected by a rod knock in the boxer motor? Could it be a bent valve? Trying to throw out every possibility.
