I took my car driving after getting the valves replaced.then the oil sign popped up then the engine started making a weird noise.I pulled over off the free way then the engine died.Overtime the hazards and lights on the dash started dimming then eventually they died.No power what so ever would come from the car and when i started the car it gave me a clicking sound like a dead battery.I checked the oil and it was low but i Did put some in.Yesterday,I jumped my car and it turned on how ever there is a loud knocking noise when Ever i hit the gas but then after awhile the car dies.No check engine light.if it was a knock in the engine wouldn't that go off?The car is full of oil now yet the oil light is still on.What could this knocking sound be?I did read online that the alternator going bad could cause a knock or could it be that the engine is now messed up do to lack of oil?any ideas?
