Vehicle very low on oil, added two quarts just to make it to safe line at dipstick. Test drove vehicle and there is no engine noises at the moment. At the shop inspected for leaks and found valve cover leaking, but the mayor one is at engine oil plug, seems to got screw in crocked. Also notice on test drive brakes with spongy feel, front rotors look like they got hot. Recommend the oil pan and valve cover for oil leaks.
