you should definitely NOT drive the car if the oil pressure warning light is on, you could destroy the engine if oil pressure is low.
Driving for a few weeks with worn valvetronic assembly and lifters would be okay, but still not a great idea to try to go too long without addressing the issues.
.Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
