Hi there I have two issues. Assistance with either would be much appreciated. 1. My Toyota Corolla 92 model is making a loud squealing noise when I am slowing down (or moving down the gears), or when I turn the engine off. When I am in neutral, after about 5-10 seconds, the noise disappears. It sounded like a fan belt issue, however after I had all new fan belts installed it still continues to make the sound. I notice that when I have had the A/C on and then I turn it off, it makes the problems worse. I took it to the mechanic and he was unable to locate the issue. Any suggestions? 2. I have noticed that I have a moderate oil leak. Does anyone know what could cause this? How to fix it? Whether these cars are prone to oil leaks? Thanks very much, I hope you can help!! Matt
