If it's a deeper knocking sound that is probably rod knock.
Clickety-clackety noise would be an indication of slightly collapsed valve tappets, and I'd personally ignore it and drive on. Could be considered normal for a car with that age and miles. If it really bothers you you could try a slightly lower viscosity engine oil at your next oil change, especially now that we're entering colder temps.
If the problem goes away when the car is warm, I'd say it sounds like valve tappets and it's really nothing to worry about. If it were something to worry about, I still wouldn't because your car is worth approximately the gas in the tank, not much more!
