Hey Scotty, I have a 93 Celica 3S GE engine. The oil light stays on for 1-2 seconds after startup and makes horrible noise like light knocking and rattling. Is that a problem? Is it going to wear out my engine? Using 5w30. Should I switch to 5w40? Using aftermarket oil filter. Thanks

do this video and pray light goes out, if not, you need a new oil pump and possible engine bearings https://www.youtube.com/watch?v=8n8YS6t3qn8

Thanks. I forgot to mention, the noises disappear as soon as the oil light goes out
