Get scared this morning when I turn on my Z the engine make a weird noise it was like there was no oil in the engine because I could hear the valves. I turner off and check the oil was little lower from the top of the one quarter mark. Get back inside and tried again and the noise was smooth but still there turn it of and try again then the noise was gone. The car was sitting for two days and is been cold but not freezing. Do this happen to any of you ?? . Do I need valves job done? Or what?. Help
