I changed my oil pan gasket, oil, and filter today. And now oil light comes on only at idle, turns off when i pass 1k rpm. Still has a slight oil leak from the oil pan like it always had, but it never turned on the oil light. Oil is fine, i checked it when it was cold and hot. Also when it drops to idle, the rpm drops to about 500 and a weird noise sounds then gets back up to 800k and no noise.

97 ls motor with 113k miles, I have no idea if the oil pump is new or still oem stock.
