So I just replaced my timing belt, tensioner, water pump, and idler pulley with the help of this guide. I do have a few questions though:

A few things that I noticed when turning the car back on. Upon first turning on the engine, I noticed a "click-click-click-click" noise coming from the passenger side of the engine. However, after a few minutes, it disappeared, and I have not heard it since. I also noticed that when I revved the engine that the revving noise had a more "crisp" sound to it than before. My guess is that the latter might be from the belt being fresh and new (vs. the crusty and worn out old one), and the former might have been something getting seated correctly. Any thoughts on this?

Despite the initial noises, I've taken the car for a spin, and nothing seems out of the ordinary. No leakage, no smells, no hesitation, explosions, or anything like that. No more clicking noise either. I just want to make sure that everything is okay...
