    Seeking for engine advice

    So I recently bought a 2002 wrx sedan with 148k it was running fine up until 4 days later I heard the knocking on my engine, check my oil it was full, it's bone stock except for a aftermarket blow off valve. I live in the Bay Area east bay I was wondering if anyone can help me what's the best thing to do now I'm on a budget, I appreciate it for your time

    Get a compression test done.

    worst comes to worst, you can find a used stock short block somewhere for $700 and swap it in (labor will be $1000+ if you can't do it or don't have a hookup).

    I fixed the video link for you

    I would take the car to a mechanic and have the mechanic use a stethoscope to determine the exact location of the noise, but I can tell you it sounds a LOT like rod knock. Sadly, bearing failure is likely. In the interim, I would drain all your oil and look for chunks of metal (especially on the drain plug).

    I'm not sure what you'd expect to see with a compression test... a motor could have complete bearing failure but still hold compression just fine

    So update on the car it is a rod knock, is there a website where I can get a short block? I'm a college student so I'm in a budget, I found an engine in Craigslist but I was looking for something that has some kind of warranty

    You could have the motor built. The builder my warranty the motor for a short time. Aside from that, you'd have to pay top dollar for an OEM piece with a warranty.

    Yes, the short block will work.

    You will need head gasket spacers or volume-matched heads to keep the compression ratio reasonable when bolted to your EJ205 heads.

    I don't understand your question. No, Subaru does not offer any of this since it's not a warrantied product.
