My car started making a ticking noise. When I opened the hood, I thought something might be rubbing. It turns out that after I removed the cap where you add oil, the ticking got significantly louder and very consistent. I added some oil to the engine, and the ticking quieted down. When the ticking happens, it's almost unnoticeable, until you take off the oil cap, and the car seems to be running just fine. However, since my last oil change, I smell faint burning oil occasionally, and it seems like I've been burning a lot more oil lately in general. What causes the ticking, and is it linked to burning oil?
