Hi everyone, I have a 99 toyota camry and just got the timing belt and serpentine belt replaced. I drove the car off the lot and almost immediately onto the highway and noticed a medium-high pitched whining sound that sounded almost electronic. It was not there before. When I got off the highway, it went away. I got home and stopped and then restarted the car again, and a pretty intense whining noise could be heard as I started the car. Again, it was not there before. I didn't drive it anymore, so I'm not sure if the noise will be there if not on the highway, but I should know tomorrow. Also, it seem as if it's taking a little longer for the car to start up, although that could be my imagination. I would really appreciate it if someone could help me out with this one. Thanks in advance for any insight anyone is able to offer.

Replying to: Mr_Shiftright (Jan 30, 2009 5:48 pm) Thanks so much for writing back. Sorry I took a shortcut and wrote you through your e-mail, ( this question was my first post on any chat site, so I don't know if that was the proper etiquette, but to be honest with you, I was so upset and frusterated, I didn't know what else to do ). I took the car back to the mechanic today and he turned it on, and said he did not hear much of a whining. I agreed with him that it was not as loud and distinct as when I just start it up after not driving it for a while ( I drove it for 35 minutes to get to his place), but it is still there. Another problem is that his shop is on a busy street, and it deffinately is harder to hear. Anyway, he told me to leave it and he will check it tomorrow am. He also said he thinks the problem is the serpentine belt he also put in and "Deffinatly NOT the timing belt." I asked why , he said that there is absolutely nothing that can be wrong with the timing belt. I asked him if it could be on too tight ( I had learned that yesterday by reading the site and was quite pleased with my question) and he said that was impossible because there are " numbers" that tell you how tight to make it. It really doesn't sound right to me, after reading some other member's writings. Another thing I asked him, and something I think is pretty crucial, is why the car is taking longer to start-it is turning over much longer than before the belt was put in. His only response was that he didn't know and he'll talk to me tomorrow. I'm hoping to get some good news tomorrow, and hope that the mechanic, who I think is a pretty honest guy ( although I haven't ben going to him for very long) will be upfront with me. I'll write an update tomorrow and hopefully it will be good news. Anyway, thanks again for your ideas- I will have to google "belt interference" and "noisy idler pulley" to find out what that is so I at least would be able to ask him about it if he tells me again nothing is wrong. Have a great night and a good weekend, Irina. PS Sorry again if this is considered too long of a post, like I said, I'm really just learning the ropes of this "chat stuff" and am just a long whinded talker in real life.

Replying to: mcdawgg (Aug 01, 2008 2:51 pm) HOWEVER I can not help but notice that several posts claim timing chains never wear out. Have they managed to create metal that does not wear? I know that the time interval is removed with metal but what about actual use? Many years ago I was in the business of auto repair. In those days we used to figure that every GM vehicle would blow a timing chain between 90,000 and 120,000 miles without fail. There were experiments with timing gears made of nylon or some plastic (which creates a time interval for replacement) or harder metals that some claimed caused noise. Any which way you looked at it, something always wore out and required replacement. The timing belt was an interesting innovation in that it introduced a predictability factor and replacement was factored into the service schedule instead of requiring the opinion of experience to advise on avoiding the use of a vehicle without warning. Those old engines used to overrun the gears on shut down. It was very common for a worn chain and or gears to suddenly allow the chain to slip instead of it breaking. A person might go to the grocery store and return to a vehicle that either would not start or one that was firing just as the valves were opening.
