I Need Engine Help pleasseee

[CleanAndLegit]

so i was driving my s13 and my oil cap was loose for some odd reason... and came off. engine spilled everywhere, and it took me about 15-20mins to notice so its smoking white smoke cause oil was hitting headers and mani. i was trying to get to my friends house because i noticed my car was starting to over heat, i plugged up the oil thing with a hankerchief. As i got on the free way and gave it gas i heard a knocking sound. i towed my car home, so this is where it gets wierd. i get home park it (still knocking), i wake up and mom and pop want me to move it so i do and tehres no knocking.... it felt good. and well im kinda tripping out.
so can anyone give me some advice of what to do?
p.s. my friend said its a spun bearing in da block.
engine is a ka24de btw

i had a ka24e do the same thing with the knockin noise, it was low on oil i added oil and it was fine for 8 months afterthat, i bet it my freind didnt swap the motor for a sr it would still be runnin lol.. pull the oilpan and look for metal chunks, that will let you know whats up... if it looks like this then its bad :(

It's probably a spun bearing due to the lack of oil. did you check oil levels?
