VERY loud whining noise
Hi all. I had a loud whining noise coming from the cam belt area. I recently,( about 3 months ago), changed the variator, which stopped this noise. However the noise came back. I had run low on oil during this period, so I bought another variator, and have just changed it. However from startup the car is now whining about 10 times louder than before, and it seems to be coming from the cam belt area. Is it possible I have a faulty variator, or could it be something else ??. This whine is at tickover and increases in pitch the higher the rev. I cannot even hear any road noise when driving as this noise is soooo loud. Please help..
