There’s nothing to fix . It’s an internal engine knock .
Drive it till it needs a new engine . You aren’t going to spend $8000 to open up the engine and rebuilt it , it’s way cheaper to buy a good used engine and have someone swap it in

It is something with a piston--either hitting combustion deposits or connecting rod bearing.
