General Site Questions   General Audi Questions   Engine Features   Performance   Engine Maintenance I have a lot of valve noise, especially when I first start the engine. It goes away after long drives but tends to stay during stop and go driving. Should I worry? My engine loses more than a quart of oil every 1000 miles. My dealer says this is normal -- is it? I have loud valve noise, all the time. What's the problem? I have loud valve noise after the car has been idling for a few minutes. What can I do about it? When should I change my timing belt? You will get conflicting advice on this. My advice will be that you should have your timing belt, timing belt tensioner, water pump, timing belt idler, and coolant thermostat replaced every 60,000 miles. Your timing belt will probably last longer than 60,000 miles, odds are good that your water pump will not last much longer than 75,000 miles. If your water pump seizes, your timing belt will break and your engine will be wrecked. The V6 is an interference engine, which means that if the timing belt breaks, the valves will strike the pistons and bend. This is very expensive to fix. Consider yourself warned. Just change the stuff every 60,000 miles. In addition to averting catastrophe, changing the timing belt gives you a good opportunity to inspect the rest of the engine. Is the V6 an interference engine? I've heard that the V6 leaks oil. Is this a big problem? Should I worry?
