oil light?????/
 

the other i went drifting and the oil light came and the motor started knocking. i noticed the dented oil pan. so i replaced that and the oil pickup with an s14 one. now the motor doesn't knock but the oil light still turns on at start for about a second. and also sometimes when the car is sideways also soemtime sat low idle. what could cause this. My guess is oil pump?

Any suggestions.

From what I recall, I believe the stock oil sensor light goes off after about 8 psi of oil pressure, or too the point where its too late to prevent knock. You should try getting yourself an oil pressure gauge to make sure your running the right amount in real time instead of waiting for the OEM one to kick in.

Stop driving the fucking car till you can verify whether its a bad sensor or a bad oil pump.

Get a real oil pressure gauge and see how fubar'd your oil pressure is. Anything less than .9 bar with the engine hot is enough to give me sleepless nights.
