for a month ago the timing belt, and all of its benefits was changed in my car. But since I got the car it has been whining somwhere from the timing are. If I step on the gas the whining just get louder? This is really annoying sound but I am so afraid that something is harming the engine. What should I do? I know it´s not an other belt, I´ve checked them out. Could this be wrong timing or could the timing belt be to tight...please ...what should I do...?

...sorry for my bad english..!
