Hi All, Is there a way to tell if a timing belt needs to be replaced? I bought a 92 300ZX, when I bought it, there was 90k mikes on the car. Nissan recommends changing the belt every 60k miles. The prior owner said he changed the belt @ 60k, but didnt have hte record. I tend to believe him b/c the car was in showroom condition when I bought it from him. The 60k maintenance on the car is about $1,000, so I'm not anxious too just have it done. TY.
