I have a 2008 Kia Optima lx with a 2.4 that has a loud knocking noise while running. There isn’t any visible damage to the pistons and it idles smooth and the oil looks good. I’m at a loss for what to do next

Probably rod knock
What did you expect after buying a Hyundai lmao
Is there any oil left in the engine
How would I diagnose that? All 4 pistons go up and down as they are supposed to
