My 99 maxima has been acting real weird. When i turn it on, if it was cold it would grind. And now the past two days when i turn it on and its cold, i would here a cluck cluck sound, i think its my valves. I suspected an oil problem and today i checked my oil level and it was practically overflowed. The last time i changed my oil was at a nissan dealer about 2000 miles ago. The grinding noise was going on before that but now im really worred after i checked my oil. Can anyone tell me what might cause the grinding noise and the cluck cluck sound. Also what happens when your engine has was too much oil in it. please help! thanks
