Hey guys, so my maxima finally broke again. At first, it started making slight grinding noises from the timing chain area, but these noises were very quiet and only seemed noticeble between 2400rpm and 3000rpm. When the idle got under 600rpm, the oil light slightly flashed. Later i added oil. One thing i noticed that is that the car was down on power above 5k rpm. Then after 40 more miles, the car started grinding more and more, and simultaneously loosing more and more power. Right now, the grinding is very loud and the car feels like it's running on 50hp. It hardly has enough power to accelerate with traffic, while having it floored. The grinding is VERY loud. The oil light now comes on when i'm under 1000rpm, and goes off when i go over 1000rpm. I added oil to it, and no change. The noise definitely sounds like it's coming form the timing chain cover, so i took the chain tensioner cover off and had a friend crank the car. The tensioner did seem to move the chain quite easily. I'm not sure if i should automatically assume that it's ok or not though, because it used to make the grinding at above 2500rpm. I just don't have money to start throwing parts at the car and hoping that i guess correctly. Also, the oil light seems to come on more as i drive more; as it, it's not on much when the engine is cold, but it comes on every time i'm under 1krpm when the engine is warm.

I don't have an IACV valve in my car because of the 00vi, but the car used to not have any idle issues whatsoever after it warmed up. Now after these grinding noises started, it will NOT idle. The idling was getting worse and worse progressively with the grinding increase, and now it doesnt idle at all.


so...any ideas? this car is my DD and i really can't afford not to have a car.


chain skipped a tooth? wtf?

One thread is enough. It's better suited over there anyway.
