Default 97 sti started making terrible noises (soundclip)

Firs things first if you don't want to read, perhaps you can still have a listen:

Recently imported a 97 sti v4 type RA (84k km) I've been driving it just about a week now and it was running great. Just got the oil changed yesterday and later that night, I started hearing a rattling noise. Hardly noticeable when idling, it would get louder up to about 4k rpm and then I couldn't really hear it after that.

It was still running perfectly fine but I was fairly concerned about the rattle so I parked it last night and today I went to drive it maybe 2-3km to a mechanic friend's house so he could have a look at it. About 2 blocks from his house, it died while I was taking a turn and wouldn't start. Rolled it to his house and finally got it started up after putting it in 5th and rocking the car a bit to loosen it up I guess and now there's a couple other terrible noises, the rattle seems to be the least of my worries now.

We checked the starter, AC, power steering belts and had a look at (I think half of) the timing belt. Couldn't get at the other half very easily. None of those seem to be the issue.

I'm not sure what other information might be useful as this isn't really my area of expertise but if there's anything else I can tell to help diagnose this, just let me know. Really appreciate any help!

Lots of head noise, rod knock also. If it has 84km on it, that's plenty of time to get abused. Probably bought a bad motor, or ran it too hard too soon if it was sitting for a while before you dropped it in.

That doesn't sound good at all. Definitely some rod knocking and some messed up heads there. Best of luck though.

it definitely sounds like a rod knock, i would stop the car. Do not start the engine, you need to tear that engine apart and see the damage, i would recommend you to get a new dual thrust , double cross-drilled crankshaft, acl maim and rod bearinga, if your cylinder walls are not damage neither your pistons, you could save money and keep those that are like semi forged from the factory, just get a new set of OEM std size piston rings, new oil pump and oil cooler as well. If you cannot get your engine tune , i would recommend you to use a thicker head gasket mate, stock one is 1,37 mm. Use a 1,5 mm in order to reduce det. Thats what i did on my car and runs like a champ!. im sorry to heard this mate.. You definitely need to rebuild your ej20k engine
