Car starts and motor runs fine for about 15 minutes. Then temp gauge starts rising and the motor begins piinging, the oil light starts fading on and the motor quits. After 3-4 hours it starts up fine. The motor is obviously hot and the new oil I just changed is looking dark. Initially the temp gauge only went up to about 2/3rds of the dial. Now it's going right up to Red Line unless I back off on the gas. The coolant is then down a bunch. One mechanic thinks it's a thermostat or water pump. Another mechanic says it's the oil pump. Any thoughts?
