Default 2003 wrx tapping noise

Sup guys, this is mostly for local people but im sure you guys can help to and i greatly appreciate it if you do.

My car last night just randomly started making this loud tapping noise. I don't have a boost gauge but I believe it is no longer hitting boost due to the fact that if you accelerate it, it revs up slowly and unsteadily and there is NO power at all.

Two days ago I changed my oil, oil filter, and also put a K&N drop in air filter. I drove the car for about 100-150 miles after that and it was perfectly fine, as a matter of fact I felt boost smoother.

Its an 03 wrx with a full catless exhaust, no tune on it. It has 142,187 miles.

I need this fixed ASAP, if anyone on here can help I would highly appreciate it and purchase food/drinks and I'll pay you for your co-operation/gas. This is my only way of transportation and being the main source of income at my house I'll need it fixed fast because I cannot be missing work.

Thanks in advance
My # is 7865416278, I can send you a video of the noise if it would help.

Could be many things. Look up WRX or STi noise on Youtube and try to compare. Is it a bearing, a lifter, a bad coil (arching)? Not good to have no tune from what I understand. Also, did you get any particles in the oil via the drain plug or filter or filler neck? Particles or dirt can clog oil holes and cause issues or even eat bearings. Try to take extra care when changing oil and doing work.

Best of luck.

Yea the oil is clean, even though I haven't been able to check the drain plug because I got called into work. I asked my local Subaru guys and one of them might pass by today hopefully to see it. And someone who I sent an audio clip to said he's never heard that noise but it's definitely bad.

It is worse when the engine is cold? Valvetrain noise is normal and can be caused by clogged oil lines in the heads but poor turbo performance indicates something else. Or your oil lines in the head are ****ed and it's killing oil pressure to the turbo.

I actually haven't let it warm up since it made the noise. I've just turned it on to record an audio clip and to check if maybe it stopped (guess my prayers and tears didn't work) lol

I mean I'm hoping that it is what one of my friends said and he said it could most probably be a belt tensioner or the timing belt "if" there's no metal debris or shaving in the oil. Which I have to take the drain plug out

you can use a technician's stethoscope or even a ong skinny screwdriver to narrow down the noise. touch valve covers, then below a/c compressor (the bracket where the tbelt tensioner mounts) then the "spine" of the block.

odds are, depending on mileage, it's a tbelt tensioner. or, if you did the tbelt and didnt replace it (most guys throw water pumps on that aren't needed, but skip the tensioner, even if it's puking hydraulic oil...)

Alright I'll look into that today. My boss is being a d*** and won't let me take a day off.

Thanks though
